Single-Chip 5G WiFi IEEE 802.11ac 2×2 MAC/

Baseband/Radio with Integrated Bluetooth 4.1,

FM Receiver, and Wireless Charging

The Cypress CYW4356 is a complete dual-band (2.4 GHz and 5 GHz) 5G WiFi 2 × 2 MIMO MAC/PHY/Radio System-on-a-Chip. This

Wi-Fi single-chip device provides a high level of integration with dual-stream IEEE 802.11ac MAC/baseband/radio, Bluetooth 4.1, and

FM radio receiver. Additionally, it supports wireless charging. In IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–

MCS9 (up to 256 QAM) in 20 MHz, 40 MHz, and 80 MHz channels for data rates up to 867 Mbps. In addition, all the rates specified

in IEEE 802.11a/b/g/n are supported. Included on-chip are 2.4 GHz and 5 GHz transmit power amplifiers and receive low noise

amplifiers.

For the WLAN section, several alternative host interface options are included: an SDIO v3.0 interface that can operate in 4b or 1b

modes, and a PCIe v3.0 compliant interface running at Gen1 speeds. For the Bluetooth section, host interface options of a high-speed

4-wire UART and USB 2.0 full-speed (12 Mbps) are provided.

The CYW4356 uses advanced design techniques and process technology to reduce active and idle power, and includes an embedded

power management unit that simplifies the system power topology.

In addition, the CYW4356 implements highly sophisticated enhanced collaborative coexistence hardware mechanisms and algorithms

that ensure that WLAN and Bluetooth collaboration is optimized for maximum performance. Coexistence support for external radios

(such as LTE cellular and GPS) is provided via an external interface. As a result, enhanced overall quality for simultaneous voice,

video, and data transmission on a handheld system is achieved.

This data sheet provides details on the functional, operational, and electrical characteristics for the Cypress CYW4356. It is intended

for hardware design, application, and OEM engineers.

CYW4356

2. Power Supplies and Power Management

2.1 Power Supply Topology

One Buck regulator, multiple LDO regulators, and a power management unit (PMU) are integrated into the CYW4356. All regulators

are programmable via the PMU. These blocks simplify power supply design for Bluetooth, WLAN, and FM functions in embedded

designs.

A single VBAT (3.0V to 5.25V DC max.) and VIO supply (1.8V to 3.3V) can be used, with all additional voltages being provided by the

regulators in the CYW4356.

Two control signals, BT_REG_ON and WL_REG_ON, are used to power-up the regulators and take the respective section out of

reset. The CBUCK CLDO and LNLDO power up when any of the reset signals are deasserted. All regulators are powered down only

when both BT_REG_ON and WL_REG_ON are deasserted. The CLDO and LNLDO may be turned off/on based on the dynamic

demands of the digital baseband.

The CYW4356 allows for an extremely low power-consumption mode by completely shutting down the CBUCK, CLDO, and LNLDO

regulators. When in this state, LPLDO1 (which is a low-power linear regulator supplied by the system VIO supply) provides the

CYW4356 with all the voltages it requires, further reducing leakage currents.

2.2 CYW4356 PMU Features

■ VBAT to 1.35Vout (600 mA maximum) Core-Buck (CBUCK) switching regulator

■ VBAT to 3.3Vout (600 mA maximum) LDO3P3

■ VBAT to 3.3Vout (150 mA maximum) LDO3P3_B

■ VBAT to 2.5V out (70 mA maximum) BTLDO2P5

■ 1.35V to 1.2Vout (150 mA maximum) LNLDO

■ 1.35V to 1.2Vout (300 mA maximum) CLDO with bypass mode for deep-sleep

■ Additional internal LDOs (not externally accessible)

CYW4356

2.3 WLAN Power Management

The CYW4356 has been designed with the stringent power consumption requirements of mobile devices in mind. All areas of the chip

design are optimized to minimize power consumption. Silicon processes and cell libraries were chosen to reduce leakage current and

supply voltages. Additionally, the CYW4356 integrated RAM is a high Vt memory with dynamic clock control. The dominant supply

current consumed by the RAM is leakage current only. Additionally, the CYW4356 includes an advanced WLAN power management

unit (PMU) sequencer. The PMU sequencer provides significant power savings by putting the CYW4356 into various power

management states appropriate to the current environment and activities that are being performed. The power management unit

enables and disables internal regulators, switches, and other blocks based on a computation of the required resources and a table

that describes the relationship between resources and the time needed to enable and disable them. Power up sequences are fully

programmable. Configurable, free-running counters (running at 32.768 kHz LPO clock) in the PMU sequencer are used to turn on/

turn off individual regulators and power switches. Clock speeds are dynamically changed (or gated altogether) for the current mode.

Slower clock speeds are used wherever possible.

The CYW4356 WLAN power states are described as follows:

■ Active mode—All WLAN blocks in the CYW4356 are powered up and fully functional with active carrier sensing and frame

transmission and receiving. All required regulators are enabled and put in the most efficient mode based on the load current. Clock

speeds are dynamically adjusted by the PMU sequencer.

■ Deep-sleep mode—Most of the chip including both analog and digital domains and most of the regulators are powered off. All main

clocks (PLL, crystal oscillator, or TCXO) are shut down to reduce active power to the minimum. The 32.768 kHz LPO clock is

available only for the PMU sequencer. This condition is necessary to allow the PMU sequencer to wake up the chip and transition

to Active mode. Logic states in the digital core are saved and preserved into a retention memory in the always-ON domain before

the digital core is powered off. Upon a wake-up event triggered by the PMU timers, an external interrupt or a host resumes through

the SDIO bus and logic states in the digital core are restored to their pre-deep-sleep settings to avoid lengthy HW reinitialization.

In Deep-sleep mode, the primary source of power consumption is leakage current.

■ Power-down mode—The CYW4356 is effectively powered off by shutting down all internal regulators. The chip is brought out of

this mode by external logic reenabling the internal regulators.

2.4 PMU Sequencing

The PMU sequencer is responsible for minimizing system power consumption. It enables and disables various system resources

based on a computation of the required resources and a table that describes the relationship between resources and the time needed

to enable and disable them.

Resource requests may come from several sources: clock requests from cores, the minimum resources defined in the ResourceMin

register, and the resources requested by any active resource request timers. The PMU sequencer maps clock requests into a set of

resources required to produce the requested clocks.

Each resource is in one of four states: enabled, disabled, transition_on, and transition_off and has a timer that contains 0 when the

resource is enabled or disabled and a non-zero value in the transition states. The timer is loaded with the time_on or time_off value

of the resource when the PMU determines that the resource must be enabled or disabled. That timer decrements on each 32.768 kHz

PMU clock. When it reaches 0, the state changes from transition_off to disabled or transition_on to enabled. If the time_on value is

0, the resource can go immediately from disabled to enabled. Similarly, a time_off value of 0 indicates that the resource can go

immediately from enabled to disabled. The terms enable sequence and disable sequence refer to either the immediate transition or

the timer load-decrement sequence.

During each clock cycle, the PMU sequencer performs the following actions:

■ Computes the required resource set based on requests and the resource dependency table.

■ Decrements all timers whose values are non zero. If a timer reaches 0, the PMU clears the ResourcePending bit for the resource

and inverts the ResourceState bit.

■ Compares the request with the current resource status and determines which resources must be enabled or disabled.

■ Initiates a disable sequence for each resource that is enabled, no longer being requested, and has no powered up dependents.

■ Initiates an enable sequence for each resource that is disabled, is being requested, and has all of its dependencies enabled.

CYW4356

2.5 Power-Off Shutdown

The CYW4356 provides a low-power shutdown feature that allows the device to be turned off while the host, and any other devices

in the system, remain operational. When the CYW4356 is not needed in the system, VDDIO_RF and VDDC are shut down while VBAT

and VDDIO remain powered. This allows the CYW4356 to be effectively off while keeping the I/O pins powered so that they do not

draw extra current from any other devices connected to the I/O.

During a low-power shut-down state, provided VDDIO remains applied to the CYW4356, all outputs are tristated, and most inputs

signals are disabled. Input voltages must remain within the limits defined for normal operation. This is done to prevent current paths

or create loading on any digital signals in the system, and enables the CYW4356 to be fully integrated in an embedded device and

take full advantage of the lowest power-savings modes.

When the CYW4356 is powered on from this state, it is the same as a normal power-up and the device does not retain any information

about its state from before it was powered down.

2.6 Power-Up/Power-Down/Reset Circuits

The CYW4356 has two signals (see Table 3) that enable or disable the Bluetooth and WLAN circuits and the internal regulator blocks,

allowing the host to control power consumption. For timing diagrams of these signals and the required power-up sequences, see

Section 21. Power-Up Sequence and Timing.

Table 3. Power-Up/Power-Down/Reset Control Signals

Signal

WL_REG_ON

Description

This signal is used by the PMU (with BT_REG_ON) to power up the WLAN section. It is also OR-gated

with the BT_REG_ON input to control the internal CYW4356 regulators. When this pin is high, the

regulators are enabled and the WLAN section is out of reset. When this pin is low, the WLAN section

is in reset. If BT_REG_ON and WL_REG_ON are both low, the regulators are disabled. This pin has

an internal 200 k pull-down resistor that is enabled by default. It can be disabled through programming.

BT_REG_ON

This signal is used by the PMU (with WL_REG_ON) to decide whether or not to power down the internal

CYW4356 regulators. If BT_REG_ON and WL_REG_ON are low, the regulators will be disabled. This

pin has an internal 200 k pull-down resistor that is enabled by default. It can be disabled through

programming.

2.7 Wireless Charging

The CYW4356 combo IC is designed for paired operation with the BCM59350 wireless power transfer front-end chip. Working

together, the two chips form a power receiver unit (PRU) that is compliant with the Alliance for Wireless Power specification (A4WP).

High-level functional block diagram for wireless charging is provided in Figure 4. The power transmit unit (PTU) resides in the charging

pad while the power receive unit is integrated into the mobile device. The charging process begins as the mobile device is placed onto

the charging pad. The power is transferred from PTU to PRU through the TX and RX coils by means of magnetic induction. The

Bluetooth control link handles communications, i.e., handshaking, between them. PTU is a BLE client, which gets performance data

from the BLE server (PRU) in order to adapt its power to the mobile's need.

3. Frequency References

An external crystal is used for generating all radio frequencies and normal operation clocking. As an alternative, an external frequency

reference may be used. In addition, a low-power oscillator (LPO) is provided for lower power mode timing.

3.1 Crystal Interface and Clock Generation

The CYW4356 can use an external crystal to provide a frequency reference. The recommended configuration for the crystal oscillator

including all external components is shown in Figure 7. Consult the reference schematics for the latest configuration.

schem atics for details.

A fractional-N synthesizer in the CYW4356 generates the radio frequencies, clocks, and data/packet timing, enabling it to operate

using a wide selection of frequency references.

For SDIO and PCIe WLAN host applications, the recommended default frequency reference is a 37.4 MHz crystal. For PCIe applica-

tions, see Table 4 for details on alternatives for the external frequency reference. The signal characteristics for the crystal oscillator

interface are also listed in Table 4.

Note: Although the fractional-N synthesizer can support alternative reference frequencies, frequencies other than the default require

support to be added in the driver, plus additional extensive system testing. Contact Cypress for further details.

3.2 External Frequency Reference

For operation in SDIO mode only, an alternative to a crystal (an external precision frequency reference) can be used. The recom-

mended default frequency is 52 MHz ±10 ppm, and it must meet the phase noise requirements listed in Table 4.

If used, the external clock should be connected to the WRF_XTAL_IN pin through an external 1000 pF coupling capacitor, as shown

in Figure 8. The internal clock buffer connected to this pin will be turned OFF when the CYW4356 goes into sleep mode. When the

clock buffer turns ON and OFF there will be a small impedance variation. Power must be supplied to the WRF_XTAL_VDD1P5 pin.

3.3 External 32.768 kHz Low-Power Oscillator

The CYW4356 uses a secondary low-frequency clock for Low-Power mode timing. Either the internal low- precision LPO or an external

32.768 kHz precision oscillator is required. The internal LPO frequency range is approximately 33 kHz (± 30%) over process, voltage,

and temperature, which is adequate for some applications. However, one trade-off caused by this wide LPO tolerance is a small current

consumption increase during power save mode that is incurred by the need to wake up earlier to avoid missing beacons.

Whenever possible, the preferred approach is to use a precision external 32.768 kHz clock which meets the requirements listed in

4. Bluetooth + FM Subsystem Overview

The Cypress CYW4356 is a Bluetooth 4.1 + EDR-compliant, baseband processor/2.4 GHz transceiver with an integrated FM/RDS/

RBDS receiver. It features the highest level of integration and eliminates all critical external components, thus minimizing the footprint,

power consumption, and system cost of a Bluetooth plus FM radio solution.

The CYW4356 is the optimal solution for any Bluetooth voice and/or data application that also requires an FM radio receiver. The

Bluetooth subsystem presents a standard Host Controller Interface (HCI) via a high-speed UART and PCM for audio. The FM

4.2 Bluetooth Radio

The CYW4356 has an integrated radio transceiver that has been optimized for use in 2.4 GHz Bluetooth wireless systems. It has been

designed to provide low-power, low-cost, robust communications for applications operating in the globally available 2.4 GHz

unlicensed ISM band. It is fully compliant with the Bluetooth Radio Specification and EDR specification and meets or exceeds the

requirements to provide the highest communication link quality of service.

4.2.1 Transmit

The CYW4356 features a fully integrated zero-IF transmitter. The baseband transmit data is GFSK-modulated in the modem block

and upconverted to the 2.4 GHz ISM band in the transmitter path. The transmitter path consists of signal filtering, I/Q upconversion,

output power amplifier, and RF filtering. The transmitter path also incorporates /4-DQPSK for 2 Mbps and 8-DPSK for 3 Mbps to

support EDR. The transmitter section is compatible to the Bluetooth Low Energy specification. The transmitter PA bias can also be

adjusted to provide Bluetooth class 1 or class 2 operation.

4.2.2 Digital Modulator

The digital modulator performs the data modulation and filtering required for the GFSK, /4-DQPSK, and

8-DPSK signal. The fully digital modulator minimizes any frequency drift or anomalies in the modulation characteristics of the trans-

mitted signal and is much more stable than direct VCO modulation schemes.

4.2.3 Digital Demodulator and Bit Synchronizer

The digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency tracking and bit-

synchronization algorithm.

4.2.4 Power Amplifier

The fully integrated PA supports Class 1 or Class 2 output using a highly linearized, temperature-compensated design. This provides

greater flexibility in front-end matching and filtering. Due to the linear nature of the PAcombined with some integrated filtering, external

filtering is required to meet the Bluetooth and regulatory harmonic and spurious requirements. For integrated mobile handset appli-

cations in which Bluetooth is integrated next to the cellular radio, external filtering can be applied to achieve near thermal noise levels

for spurious and radiated noise emissions. The transmitter features a sophisticated on-chip transmit signal strength indicator (TSSI)

block to keep the absolute output power variation within a tight range across process, voltage, and temperature.

Document Number: 002-15053 Rev. *D

Page 20 of 155

ADVANCE

CYW4356

4.2.5 Receiver

The receiver path uses a low-IF scheme to downconvert the received signal for demodulation in the digital demodulator and bit

synchronizer. The receiver path provides a high degree of linearity, an extended dynamic range, and high-order on-chip channel

filtering to ensure reliable operation in the noisy 2.4 GHz ISM band. The front-end topology with built-in out-of-band attenuation

enables the CYW4356 to be used in most applications with minimal off-chip filtering. For integrated handset operation, in which the

Bluetooth function is integrated close to the cellular transmitter, external filtering is required to eliminate the desensitization of the

receiver by the cellular transmit signal.

4.2.6 Digital Demodulator and Bit Synchronizer

The digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency tracking and bit

synchronization algorithm.

4.2.7 Receiver Signal Strength Indicator

The radio portion of the CYW4356 provides a Receiver Signal Strength Indicator (RSSI) signal to the baseband, so that the controller

can take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determine whether the

transmitter should increase or decrease its output power.

4.2.8 Local Oscillator Generation

Local Oscillator (LO) generation provides fast frequency hopping (1600 hops/second) across the 79 maximum available channels.

The LO generation subblock employs an architecture for high immunity to LO pulling during PA operation. The CYW4356 uses an

internal RF and IF loop filter.

4.2.9 Calibration

The CYW4356 radio transceiver features an automated calibration scheme that is fully self contained in the radio. No user interaction

is required during normal operation or during manufacturing to provide the optimal performance. Calibration optimizes the perfor-

mance of all the major blocks within the radio to within 2% of optimal conditions, including gain and phase characteristics of filters,

matching between key components, and key gain blocks. This takes into account process variation and temperature variation.

Calibration occurs transparently during normal operation during the settling time of the hops and calibrates for temperature variations

as the device cools and heats during normal operation in its environment.

5. Bluetooth Baseband Core

The Bluetooth Baseband Core (BBC) implements all of the time critical functions required for high-performance Bluetooth operation.

The BBC manages the buffering, segmentation, and routing of data for all connections. It also buffers data that passes through it,

handles data flow control, schedules SCO/ACLTX/RX transactions, monitors Bluetooth slot usage, optimally segments and packages

data into baseband packets, manages connection status indicators, and composes and decodes HCI packets. In addition to these

functions, it independently handles HCI event types, and HCI command types.

The following transmit and receive functions are also implemented in the BBC hardware to increase reliability and security of the TX/

RX data before sending over the air:

■ Symbol timing recovery, data deframing, forward error correction (FEC), header error control (HEC), cyclic redundancy check

(CRC), data decryption, and data dewhitening in the receiver.

■ Data framing, FEC generation, HEC generation, CRC generation, key generation, data encryption, and data whitening in the

transmitter.

5.1 Bluetooth 4.1 Features

The BBC supports all Bluetooth 4.1 features, with the following benefits:

■ Dual-mode bluetooth Low Energy (BT and BLE operation)

■ Extended Inquiry Response (EIR): Shortens the time to retrieve the device name, specific profile, and operating mode.

■ Encryption Pause Resume (EPR): Enables the use of Bluetooth technology in a much more secure environment.

■ Sniff Subrating (SSR): Optimizes power consumption for low duty cycle asymmetric data flow, which subsequently extends battery

life.

■ Secure Simple Pairing (SSP): Reduces the number of steps for connecting two devices, with minimal or no user interaction required.

■ Link Supervision Time Out (LSTO): Additional commands added to HCI and Link Management Protocol (LMP) for improved link

time-out supervision.

■ QoS enhancements: Changes to data traffic control, which results in better link performance. Audio, human interface device (HID),

bulk traffic, SCO, and enhanced SCO (eSCO) are improved with the erroneous data (ED) and packet boundary flag (PBF) enhance-

ments.

5.2 Bluetooth Low Energy

The CYW4356 supports the Bluetooth Low Energy operating mode.

5.3 Link Control Layer

The link control layer is part of the Bluetooth link control functions that are implemented in dedicated logic in the link control unit (LCU).

This layer consists of the command controller that takes commands from the software, and other controllers that are activated or

configured by the command controller, to perform the link control tasks. Each task performs a different state in the Bluetooth Link

Controller.

5.4 Test Mode Support

The CYW4356 fully supports Bluetooth Test mode as described in Part I:1 of the Specification of the Bluetooth System Version 3.0.

This includes the transmitter tests, normal and delayed loopback tests, and reduced hopping sequence.

In addition to the standard Bluetooth Test Mode, the CYW4356 also supports enhanced testing features to simplify RF debugging and

qualification and type-approval testing. These features include:

■ Fixed frequency carrier wave (unmodulated) transmission

❐ Simplifies some type-approval measurements (Japan)

❐ Aids in transmitter performance analysis

■ Fixed frequency constant receiver mode

❐ Receiver output directed to I/O pin

❐ Allows for direct BER measurements using standard RF test equipment

❐ Facilitates spurious emissions testing for receive mode

■ Fixed frequency constant transmission

❐ Eight-bit fixed pattern or PRBS-9

❐ Enables modulated signal measurements with standard RF test equipment

5.5 Bluetooth Power Management Unit

The Bluetooth Power Management Unit (PMU) provides power management features that can be invoked by either software through

power management registers or packet handling in the baseband core. The power management functions provided by the CYW4356

are:

■ RF Power Management

■ Host Controller Power Management

■ BBC Power Management

■ FM Power Management

5.5.1 RF Power Management

The BBC generates power-down control signals for the transmit path, receive path, PLL, and power amplifier to the 2.4 GHz trans-

ceiver. The transceiver then processes the power-down functions accordingly.

5.5.2 Host Controller Power Management

When running in UART mode, the CYW4356 may be configured so that dedicated signals are used for power management hand-

shaking between the CYW4356 and the host. The basic power saving functions supported by those hand-shaking signals include the

standard Bluetooth defined power savings modes and standby modes of operation. Table 6 describes the power-control hand-shake

signals used with the UART interface.

CYW4356

5.5.3 BBC Power Management

The following are low-power operations for the BBC:

■ Physical layer packet-handling turns the RF on and off dynamically within transmit/receive packets.

■ Bluetooth-specified low-power connection modes: sniff, hold, and park. While in these modes, the CYW4356 runs on the low-power

oscillator and wakes up after a predefined time period.

■ A low-power shutdown feature allows the device to be turned off while the host and any other devices in the system remain

operational. When the CYW4356 is not needed in the system, the RF and core supplies are shut down while the I/O remains

powered. This allows the CYW4356 to effectively be off while keeping the I/O pins powered so they do not draw extra current from

any other devices connected to the I/O.

During the low-power shut-down state, provided VDDIO remains applied to the CYW4356, all outputs are tristated, and most input

signals are disabled. Input voltages must remain within the limits defined for normal operation. This is done to prevent current

paths or create loading on any digital signals in the system and enables the CYW4356 to be fully integrated in an embedded

device to take full advantage of the lowest power-saving modes.

Two CYW4356 input signals are designed to be high-impedance inputs that do not load the driving signal even if the chip does

not have VDDIO power supplied to it: the frequency reference input (WRF_TCXO_IN) and the 32.768 kHz input (LPO). When the

CYW4356 is powered on from this state, it is the same as a normal power-up, and the device does not contain any information

about its state from the time before it was powered down.

5.5.4 FM Power Management

The CYW4356 FM subsystem can operate independently of, or in tandem with, the Bluetooth RF and BBC subsystems. The FM

subsystem power management scheme operates in conjunction with the Bluetooth RF and BBC subsystems. The FM block does not

have a low power state, it is either on or off.

5.5.5 Wideband Speech

The CYW4356 provides support for wideband speech (WBS) using on-chip SmartAudio technology. The CYW4356 can perform

subband-codec (SBC), as well as mSBC, encoding and decoding of linear 16 bits at 16 kHz (256 Kbps rate) transferred over the PCM

bus.

5.5.6 Packet Loss Concealment

Packet Loss Concealment (PLC) improves apparent audio quality for systems with marginal link performance. Bluetooth messages

are sent in packets. When a packet is lost, it creates a gap in the received audio bit-stream. Packet loss can be mitigated in several

ways:

■ Fill in zeros.

■ Ramp down the output audio signal toward zero (this is the method used in current Bluetooth headsets).

■ Repeat the last frame (or packet) of the received bit-stream and decode it as usual (frame repeat).

These techniques cause distortion and popping in the audio stream. The CYW4356 uses a proprietary waveform extension algorithm

to provide dramatic improvement in the audio quality. Figure 10 and Figure 11 show audio waveforms with and without Packet Loss

Concealment. Cypress PLC/BEC algorithms also support wideband speech.

5.5.7 Audio Rate-Matching Algorithms

The CYW4356 has an enhanced rate-matching algorithm that uses interpolation algorithms to reduce audio stream jitter that may be

present when the rate of audio data coming from the host is not the same as the Bluetooth or FM audio data rates.

5.5.8 Codec Encoding

The CYW4356 can support SBC and mSBC encoding and decoding for wideband speech.

5.5.9 Multiple Simultaneous A2DP Audio Stream

The CYW4356 has the ability to take a single audio stream and output it to multiple Bluetooth devices simultaneously. This allows a

user to share his or her music (or any audio stream) with a friend.

5.5.10 FM Over Bluetooth

FM Over Bluetooth enables the CYW4356 to stream data from FM over Bluetooth without requiring the host to be awake. This can

significantly extend battery life for usage cases where someone is listening to FM radio on a Bluetooth headset.

5.5.11 Burst Buffer Operation

The CYW4356 has a data buffer that can buffer data being sent over the HCI and audio transports, then send the data at an increased

rate. This mode of operation allows the host to sleep for the maximum amount of time, dramatically reducing system current

consumption.

5.6 Adaptive Frequency Hopping

The CYW4356 gathers link quality statistics on a channel by channel basis to facilitate channel assessment and channel map

selection. The link quality is determined using both RF and baseband signal processing to provide a more accurate frequency-hop

map.

5.7 Advanced Bluetooth/WLAN Coexistence

The CYW4356 includes advanced coexistence technologies that are only possible with a Bluetooth/WLAN integrated die solution.

These coexistence technologies are targeted at small form-factor platforms, such as cell phones and media players, including appli-

cations such as VoWLAN + SCO and Video-over-WLAN + High Fidelity BT Stereo.

Support is provided for platforms that share a single antenna between Bluetooth and WLAN. Dual-antenna applications are also

supported. The CYW4356 radio architecture allows for lossless simultaneous Bluetooth and WLAN reception for shared antenna

applications. This is possible only via an integrated solution (shared LNAand joint AGC algorithm). It has superior performance versus

implementations that need to arbitrate between Bluetooth and WLAN reception.

The CYW4356 integrated solution enables MAC-layer signaling (firmware) and a greater degree of sharing via an enhanced coexis-

tence interface. Information is exchanged between the Bluetooth and WLAN cores without host processor involvement.

The CYW4356 also supports Transmit Power Control on the STA together with standard Bluetooth TPC to limit mutual interference

and receiver desensitization. Preemption mechanisms are utilized to prevent AP transmissions from colliding with Bluetooth frames.

Improved channel classification techniques have been implemented in Bluetooth for faster and more accurate detection and elimi-

nation of interferers (including non-WLAN 2.4 GHz interference).

The Bluetooth AFH classification is also enhanced by the WLAN core’s channel information.

5.8 Fast Connection (Interlaced Page and Inquiry Scans)

The CYW4356 supports page scan and inquiry scan modes that significantly reduce the average inquiry response and connection

times. These scanning modes are compatible with the Bluetooth version 2.1 page and inquiry procedures.

6. Microprocessor and Memory Unit for Bluetooth

The Bluetooth microprocessor core is based on the ARM Cortex-M3 32-bit RISC processor with embedded ICE-RT debug and JTAG

interface units. It runs software from the link control (LC) layer, up to the host controller interface (HCI).

The ARM core is paired with a memory unit that contains 668 KB of ROM memory for program storage and boot ROM, 200 KB of

RAM for data scratchpad and patch RAM code. The internal ROM allows for flexibility during power-on reset to enable the same device

to be used in various configurations. At power-up, the lower-layer protocol stack is executed from the internal ROM memory.

External patches may be applied to the ROM-based firmware to provide flexibility for bug fixes or features additions. These patches

may be downloaded from the host to the CYW4356 through the UART transports. The mechanism for downloading via UART is

identical to the proven interface of the CYW4330 device.

6.1 RAM, ROM, and Patch Memory

The CYW4356 Bluetooth core has 200 KB of internal RAM which is mapped between general purpose scratch pad memory and patch

memory and 668 KB of ROM used for the lower-layer protocol stack, test mode software, and boot ROM. The patch memory capability

enables the addition of code changes for purposes of feature additions and bug fixes to the ROM memory.

6.2 Reset

The CYW4356 has an integrated power-on reset circuit that resets all circuits to a known power-on state. The BT power-on reset

(POR) circuit is out of reset after BT_REG_ON goes High. If BT_REG_ON is low, then the POR circuit is held in reset.

7. Bluetooth Peripheral Transport Unit

7.1 SPI Interface

The CYW4356 supports a slave SPI HCI transport with an input clock range of up to 16 MHz. Higher clock rates can be possible. The

physical interface between the SPI master and the CYW4356 consists of the four SPI signals (SPI_CSB, SPI_CLK, SPI_SI, and

SPI_SO) and one interrupt signal (SPI_INT). The SPI signals are muxed onto the UART signals, see Table 7. The CYW4356 can be

configured to accept active-low or active-high polarity on the SPI_CSB chip select signal. It can also be configured to drive an active-

low or active-high SPI_INT interrupt signal. Bit ordering on the SPI_SI and SPI_SO data lines can be configured as either little-endian

or big-endian. Additionally, proprietary sleep mode and half-duplex handshaking is implemented between the SPI master and the

CYW4356. The SPI_INT is required to negotiate the start of a transaction. The SPI interface does not require flow control in the middle

of a payload. The FIFO is large enough to handle the largest packet size. Only the SPI master can stop the flow of bytes on the data

lines, since it controls SPI_CSB and SPI_CLK. Flow control should be implemented in the higher layer protocols.

7.2 SPI/UART Transport Detection

The BT_HOST_WAKE (BT_GPIO1) pin is also used for BT transport detection. The transport detection occurs during the power-up

sequence. It selects either UART or SPI transport operation based on the following pin state:

■ If theBT_HOST_WAKE(BT_GPIO1)pin ispulledlowbyanexternalpull-downduring power-up, itselectstheSPItransportinterface.

■ If the BT_HOST_WAKE (BT_GPIO1) pin is not pulled low externally during power-up, then the default internal pull-up is detected

as a high and it selects the UART transport interface.

When the A4WP feature is not used and USB is selected as the Bluetooth interface to the host, an external pull-up (outside the chip)

10 KΩ resistor to BT_VDDIO is required. The pull-up is not necessary but is recommended when the Bluetooth/host interface is UART

instead of USB.

7.3 PCM Interface

The CYW4356 supports two independent PCM interfaces that share the pins with the I²S interfaces. The PCM Interface on the

CYW4356 can connect to linear PCM codec devices in master or slave mode. In master mode, the CYW4356 generates the PCM_CLK

and PCM_SYNC signals, and in slave mode, these signals are provided by another master on the PCM interface and are inputs to

the CYW4356.

The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI commands.

7.3.1 Slot Mapping

The CYW4356 supports up to three simultaneous full-duplex SCO or eSCO channels through the PCM interface. These three

channels are time-multiplexed onto the single PCM interface by using a time-slotting scheme where the 8 kHz or 16 kHz audio sample

interval is divided into as many as 16 slots. The number of slots is dependent on the selected interface rate of 128 kHz, 512 kHz, or

1024 kHz. The corresponding number of slots for these interface rate is 1, 2, 4, 8, and 16, respectively. Transmit and receive PCM

data from an SCO channel is always mapped to the same slot. The PCM data output driver tristates its output on unused slots to allow

other devices to share the same PCM interface signals. The data output driver tristates its output after the falling edge of the PCM

clock during the last bit of the slot.

7.3.2 Frame Synchronization

The CYW4356 supports both short- and long-frame synchronization in both master and slave modes. In short-frame synchronization

mode, the frame synchronization signal is an active-high pulse at the audio frame rate that is a single-bit period in width and is

synchronized to the rising edge of the bit clock. The PCM slave looks for a high on the falling edge of the bit clock and expects the

first bit of the first slot to start at the next rising edge of the clock. In long-frame synchronization mode, the frame synchronization

signal is again an active-high pulse at the audio frame rate; however, the duration is three bit periods and the pulse starts coincident

with the first bit of the first slot.

CYW4356

7.3.3 Data Formatting

The CYW4356 may be configured to generate and accept several different data formats. For conventional narrowband speech mode,

the CYW4356 uses 13 of the 16 bits in each PCM frame. The location and order of these 13 bits can be configured to support various

data formats on the PCM interface. The remaining three bits are ignored on the input and may be filled with 0s, 1s, a sign bit, or a

programmed value on the output. The default format is 13-bit 2’s complement data, left justified, and clocked MSB first.

7.3.4 Wideband Speech Support

When the host encodes Wideband Speech (WBS) packets in transparent mode, the encoded packets are transferred over the PCM

bus for an eSCO voice connection. In this mode, the PCM bus is typically configured in master mode for a 4 kHz sync rate with 16-

bit samples, resulting in a 64 Kbps bit rate. The CYW4356 also supports slave transparent mode using a proprietary rate-matching

scheme. In SBC-code mode, linear 16-bit data at 16 kHz (256 Kbps rate) is transferred over the PCM bus.

7.3.5 Multiplexed Bluetooth and FM Over PCM

In this mode of operation, the CYW4356 multiplexes both FM and Bluetooth audio PCM channels over the same interface, reducing

the number of required I/Os. This mode of operation is initiated through an HCI command from the host. The format of the data stream

consists of three channels: a Bluetooth channel followed by two FM channels (audio left and right). In this mode of operation, the bus

data rate only supports 48 kHz operation per channel with 16 bits sent for each channel. This is done to allow the low data rate

Bluetooth data to coexist in the same interface as the higher speed I²S data. To accomplish this, the Bluetooth data is repeated six

times for 8 kHz data and three times for 16 kHz data. An initial sync pulse on the PCM_SYNC line is used to indicate the beginning

of the frame.

To support multiple Bluetooth audio streams within the Bluetooth channel, both 16 kHz and 8 kHz streams can be multiplexed. This

mode of operation is only supported when the Bluetooth host is the master. Figure 12 shows the operation of the multiplexed transport

with three simultaneous SCO connections. To accommodate additional SCO channels, the transport clock speed is increased. To

change between modes of operation, the transport must be halted and restarted in the new configuration.

7.3.6 Burst PCM Mode

In this mode of operation, the PCM bus runs at a significantly higher rate of operation to allow the host to duty cycle its operation and

save current. In this mode of operation, the PCM bus can operate at a rate of up to 24 MHz. This mode of operation is initiated with

an HCI command from the host.

7.4 USB Interface

7.4.1 Features

The following USB interface features are supported:

■ USB Protocol, Revision 2.0, full-speed (12 Mbps) compliant including the hub

■ Optional hub compound device with up to three device cores internal to device

■ Bus or self-power, dynamic configuration for the hub

■ Global and selective suspend and resume with remote wakeup

■ Bluetooth HCI

■ HID, DFU, UHE (proprietary method to emulate an HID device at system bootup)

■ Integrated detach resistor

7.4.2 Operation

When the A4WP feature is not used and USB is selected as the Bluetooth interface to the host, an external pull-up (outside the chip)

10 KΩ resistor to BT_VDDIO is required. The pull-up is not necessary but is recommended when the Bluetooth/host interface is UART

instead of USB.

The CYW4356 can be configured to boot up as either a single USB peripheral or a USB hub with several USB peripherals attached.

As a single peripheral, the host detects a single USB Bluetooth device. In hub mode, the host detects a hub with one to three of the

ports already connected to USB devices (see Figure 19).

Figure 19. USB Compounded Device Configuration

Host

Bluetooth

Depending on the desired hub mode configuration, the CYW4356 can boot up showing the three ports connected to logical USB

devices internal to the CYW4356: a generic Bluetooth device, a mouse, and a keyboard. In this mode, the mouse and keyboard are

emulated devices, since they connect to real HID devices via a Bluetooth link. The Bluetooth link to these HID devices is hidden from

the USB host. To the host, the mouse and/or keyboard appear to be directly connected to the USB port. This Cypress proprietary

architecture is called USB HID Emulation (UHE).

The USB device, configuration, and string descriptors are fully programmable, allowing manufacturers to customize the descriptors,

including vendor and product IDs, the CYW4356 uses to identify itself on the USB port. To make custom USB descriptor information

available at boot time, stored it in external NVRAM.

Despite the mode of operation (single peripheral or hub), the Bluetooth device is configured to include the following interfaces:

Interface 0

Interface 1

Interface 2

Contains a Control endpoint (Endpoint 0x00) for HCI commands, a Bulk In Endpoint (Endpoint 0x82) for

receiving ACL data, a Bulk Out Endpoint (Endpoint 0x02) for transmitting ACL data, and an Interrupt

Endpoint (Endpoint 0x81) for HCI events.

Contains Isochronous In and Out endpoints (Endpoints 0x83 and 0x03) for SCO traffic. Several alternate

Interface 1 settings are available for reserving the proper bandwidth of isochronous data (depending on

the application).

Contains Bulk In and Bulk Out endpoints (Endpoints 0x84 and 0x04) used for proprietary testing and

debugging purposes. These endpoints can be ignored during normal operation.

CYW4356

7.4.3 USB Hub and UHE Support

The CYW4356 supports the USB hub and device model (USB, Revision 2.0, full-speed compliant). Optional mouse and keyboard

devices utilize Cypress’s proprietary USB HID Emulation (UHE) architecture, which allows these devices appear as standalone HID

devices even though connected through a Bluetooth link.

The presence of UHE devices requires the hub to be enabled. The CYW4356 cannot appear as a single keyboard or a single mouse

device without the hub. Once either mouse or keyboard UHE device is enabled, the hub must also be enabled.

When the hub is enabled, the CYW4356 handles all standard USB functions for the following devices:

■ HID keyboard

■ HID mouse

■ Bluetooth

All hub and device descriptors are firmware-programmable. This USB compound device configuration (see Figure 19) supports up to

three downstream ports. This configuration can also be programmed to a single USB device core. The device automatically detects

activity on the USB interface when connected. Therefore, no special configuration is needed to select HCI as the transport.

The hub’s downstream port definition is as follows:

■ Port 1 USB lite device core (for HID applications)

■ Port 2 USB lite device core (for HID applications)

■ Port 3 USB full device core (for Bluetooth applications)

When operating in hub mode, all three internal devices do not have to be enabled. Each internal USB device can be optionally enabled.

The configuration record in NVRAM determines which devices are present.

CYW4356

7.5 UART Interface

The CYW4356 shares a single UART for Bluetooth and FM. The UART is a standard 4-wire interface (RX, TX, RTS, and CTS) with

adjustable baud rates from 9600 bps to 4.0 Mbps. The interface features an automatic baud rate detection capability that returns a

baud rate selection. Alternatively, the baud rate may be selected through a vendor-specific UART HCI command.

UART has a 1040-byte receive FIFO and a 1040-byte transmit FIFO to support EDR. Access to the FIFOs is conducted through the

AHB interface through either DMAor the CPU. The UART supports the Bluetooth 4.1 UART HCI specification: H4, a custom Extended

H4, and H5. The default baud rate is 115.2 Kbaud.

The UART supports the 3-wire H5 UART transport, as described in the Bluetooth specification (“Three-wire UART Transport Layer”).

Compared to H4, the H5 UART transport reduces the number of signal lines required by eliminating the CTS and RTS signals.

The CYW4356 UART can perform XON/XOFF flow control and includes hardware support for the Serial Line Input Protocol (SLIP).

It can also perform wake-on activity. For example, activity on the RX or CTS inputs can wake the chip from a sleep state.

Normally, the UART baud rate is set by a configuration record downloaded after device reset, or by automatic baud rate detection,

and the host does not need to adjust the baud rate. Support for changing the baud rate during normal HCI UART operation is included

through a vendor-specific command that allows the host to adjust the contents of the baud rate registers. The CYW4356 UARTs

operate correctly with the host UART as long as the combined baud rate error of the two devices is within ±2%.

7.6 I S Interface

The CYW4356 supports two independent I²S digital audio ports: one for Bluetooth audio, and one for high-fidelity FM audio. The I²S

interface for FM audio supports both master and slave modes. The I²S signals are:

■ I²S clock: BT_I2S_CLK

■ I²S Word Select: BT_I2S_WS

■ I²S Data Out: BT_I2S_DO

■ I²S Data In: BT_I2S_DI

BT_I2S_CLK and BT_I2S_WS become outputs in master mode and inputs in slave mode, whereas BT_I2S_DO always stays as an

output. The channel word length is 16 bits, and the data is justified so that the MSB of the left-channel data is aligned with the MSB

of the I²S bus, in accord with the I²S specification. The MSB of each data word is transmitted one bit clock cycle after the BT_I2S_WS

transition, synchronous with the falling edge of the bit clock. Left-channel data is transmitted when IBT_I2S_WS is low, and right-

channel data is transmitted when BT_I2S_WS is high. Data bits sent by the CYW4356 are synchronized with the falling edge of

BT_I2S_CLK and should be sampled by the receiver on the rising edge of BT_I2S_CLK.

The clock rate in master mode is either of the following:

48 kHz x 32 bits per frame = 1.536 MHz

48 kHz x 50 bits per frame = 2.400 MHz

The master clock is generated from the input reference clock using a N/M clock divider.

In the slave mode, any clock rate is supported to a maximum of 3.072 MHz.

a. The system clock period T must be greater than T_trand T_rbecause both the transmitter and receiver have to be able to handle the data transfer

rate.

b. At all data rates in master mode, the transmitter or receiver generates a clock signal with a fixed mark/space ratio. For this reason, t_HCand t_LC

are specified with respect to T.

c. In slave mode, the transmitter and receiver need a clock signal with minimum HIGH and LOW periods so that they can detect the signal. So

long as the minimum periods are greater than 0.35T_r, any clock that meets the requirements can be used.

d. Because the delay (t_dtr) and the maximum transmitter speed (defined by T_tr) are related, a fast transmitter driven by a slow clock edge can

result in t_dtrnot exceeding t_RCwhich means t_htrbecomes zero or negative. Therefore, the transmitter has to guarantee that t_htris greater than

or equal to zero, so long as the clock rise-time t_RCis not more than t_RCmax, where t_RCmaxis not less than 0.15T_tr.

e. To allow data to be clocked out on a falling edge, the delay is specified with respect to the rising edge of the clock signal and T, always giving

the receiver sufficient setup time.

f. The data setup and hold time must not be less than the specified receiver setup and hold time.

CYW4356

8. FM Receiver Subsystem

8.1 FM Radio

The CYW4356 includes a completely integrated FM radio receiver with RDS/RBDS covering all FM bands from 65 MHz to 108 MHz.

The receiver is controlled through commands on the HCI. FM received audio is available as stereo or in digital form through I²S or

PCM. The FM radio operates from the external clock reference.

8.2 Digital FM Audio Interfaces

The FM audio can be transmitted via the shared PCM and I²S pins, and the sampling rate is programmable. The CYW4356 supports

a three-wire PCM or I²S audio interface in either master or slave configuration. The master or slave configuration is selected using

vendor specific commands over the HCI interface. In addition, multiple sampling rates are supported, derived from either the FM or

Bluetooth clocks. In master mode, the clock rate is either of the following:

■ 48 kHz × 32 bits per frame = 1.536 MHz

■ 48 kHz × 50 bits per frame = 2.400 MHz

In slave mode, any clock rate is supported up to a maximum of 3.072 MHz.

8.3 FM Over Bluetooth

The CYW4356 can output received FM audio onto Bluetooth using one of following three links: eSCO, WBS, and A2DP. In all of the

above modes, once the link has been set up, the host processor can enter sleep mode while the CYW4356 continues to stream FM

audio to the remote Bluetooth device, allowing the system current consumption to be minimized.

8.4 eSCO

In this use case, the stereo FM audio is downsampled to 8 kHz and a mono or stereo stream is then sent through the Bluetooth eSCO

link to a remote Bluetooth device, typically a headset. Two Bluetooth voice connections must be used to transport stereo.

8.5 Wideband Speech Link

In this case, the stereo FM audio is downsampled to 16 kHz and a mono or stereo stream is then sent through the Bluetooth wideband

speech link to a remote Bluetooth device, typically a headset. Two Bluetooth voice connections must be used to transport stereo.

8.6 A2DP

In this case, the stereo FM audio is encoded by the on-chip SBC encoder and transported as an A2DP link to a remote Bluetooth

device. Sampling rates of 48 kHz, 44.1 kHz, and 32 kHz joint stereo are supported. An A2DP “lite” stack is implemented in the

CYW4356 to support this use case, which eliminates the need to route the SBC-encoded audio back to the host to create the A2DP

packets.

8.7 Autotune and Search Algorithms

The CYW4356 supports a number of FM search and tune functions that allows the host to implement many convenient user functions,

which are accessed through the Cypress FM stack.

■ Tune to Play: Allows the FM receiver to be programmed to a specific frequency.

■ Search for SNR > Threshold: Checks the power level of the available channel and the estimated SNR of the channel to help achieve

precise control of the expected sound quality for the selected FM channel. Specifically, the host can adjust its SNR requirements

to retrieve a signal with a specific sound quality, or adjust this to return the weakest channels.

■ Alternate Frequency Jump: Allows the FM receiver to automatically jump to an alternate FM channel that carries the same infor-

mation, but has a better SNR. For example, when traveling, a user may pass through a region where a number of channels carry

the same station. When the user passes from one area to the next, the FM receiver can automatically switch to another channel

with a stronger signal to spare the user from having to manually change the channel to continue listening to the same station.

CYW4356

8.8 Audio Features

A number of features are implemented in the CYW4356 to provide the best possible audio experience for the user.

■ Mono/Stereo Blend or Switch: The CYW4356 provides automatic control of the stereo or mono settings based on the FM signal

carrier-to-noise ratio (C/N). This feature is used to maintain the best possible audio SNR based on the FM channel condition. Two

modes of operation are supported:

❐ Blend: In this mode, fine control of stereo separation is used to achieve optimal audio quality over a wide range of input C/N.

The amount of separation is fully programmable. In Figure 24, the separation is programmed to maintain a minimum 50 dB SNR

across the blend range.

❐ Extended blend: In this mode, stereo separation is maximized across a wide range of input CNR. Cypress static suppression

typically gives a static-free user experience to within 3 dB of ultimate sensitivity.

Figure 24. Example Blend/Switch Usage

Document Number: 002-15053 Rev. *D

Page 43 of 155

ADVANCE

CYW4356

❐ Switch: In this mode, the audio switches from full stereo to full mono at a predetermined level to maintain optimal audio quality.

The stereo-to-mono switch point and the mono-to-stereo switch points are fully programmable to provide the desired amount of

audio SNR. In Figure 25, the switch point is programmed to switch to mono to maintain a 40 dB SNR.

Figure 25. Example Blend/Switch Separation

■ Soft Mute: Improves the user experience by dynamically muting the output audio proportionate to the FM signal C/N. This prevents

the user from being assaulted with a blast of static. The mute characteristic is fully programmable to accommodate fine tuning of

the output signal level. An example mute characteristic is shown in Figure 26.

Figure 26. Example Soft Mute Characteristic

Document Number: 002-15053 Rev. *D

Page 44 of 155

ADVANCE

CYW4356

■ High Cut: A programmable high-cut filter is provided to reduce the amount of high-frequency noise caused by static in the output

audio signal. Like the soft mute circuit, it is fully programmable to allow for any amount of high cut based on the FM signal C/N.

■ Audio Pause Detect: The FM receiver monitors the magnitude of the audio signal and notifies the host through an interrupt when

the magnitude of the signal has fallen below the threshold set for a programmable period. This feature can be used to provide

alternate frequency jumps during periods of silence to minimize disturbances to the listener. Filtering techniques are used within

the audio pause detection block to provide more robust presence-to-silence detection and silence-to-presence detection.

■ Automatic Antenna Tuning: The CYW4356 has an on-chip automatic antenna tuning network. When used with a single off-chip

inductor, the on-chip circuitry automatically chooses an optimal on-chip matching component to obtain the highest signal strength

for the desired frequency. The high-Q nature of this matching network simultaneously provides out-of-band blocking protection as

well as a reduction of radiated spurious emissions from the FM antenna. It is designed to accommodate a wide range of external

wire antennas.

8.9 RDS/RBDS

The CYW4356 integrates a RDS/RBDS modem and codec, the decoder includes programmable filtering and buffering functions, and

the encoder includes the option to encode messages to PS or RT frame format with programmable scrolling in PS mode. The RDS/

RBDS data can be read out in receive mode or delivered in transmit mode through either the HCI interface.

In addition, the RDS/RBDS functionality supports the following:

Receive

■ Block decoding, error correction and synchronization

■ Flywheel synchronization feature, allowing the host to set parameters for acquisition, maintenance, and loss of sync. (It is possible

to set up the CYW4356 such that synch is achieved when a minimum of two good blocks (error free) are decoded in sequence.

The number of good blocks required for sync is programmable.)

■ Storage capability up to 126 blocks of RDS data

■ Full or partial block B match detect and interrupt to host

■ Audio pause detection with programmable parameters

■ Program Identification (PI) code detection and interrupt to host

■ Automatic frequency jump

■ Block E filtering

■ Soft mute

■ Signal dependent mono/stereo blend

■ Programmable preemphasis

9. WLAN Global Functions

9.1 WLAN CPU and Memory Subsystem

The CYW4356 WLAN section includes an integrated ARM Cortex-R4 32-bit processor with internal RAM and ROM. The ARM Cortex-

R4 is a low-power processor that features low gate count, low interrupt latency, and low-cost debug capabilities. It is intended for

deeply embedded applications that require fast interrupt response features. Delivering a performance gain of more than 30% over

the ARM7TDMI processor, the ARM Cortex-R4 processor implements the ARM v7-R architecture with support for the Thumb-2

instruction set.

At 0.19 µW/MHz, the Cortex-R4 is the most power efficient general-purpose microprocessor available, outperforming 8- and 16-bit

devices on MIPS/µW.

Using multiple technologies to reduce cost, the ARM Cortex-R4 offers improved memory utilization, reduced pin overhead, and

reduced silicon area. It supports independent buses for Code and Data access (ICode/DCode and System buses), integrated sleep

modes, and extensive debug features including real time trace of program execution.

On-chip memory for the CPU includes 768 KB SRAM and 640 KB ROM.

9.2 One-Time Programmable Memory

Various hardware configuration parameters may be stored in an internal One-Time Programmable (OTP) memory, which is read by

the system software after device reset. In addition, customer-specific parameters, including the system vendor ID and the MAC

address can be stored, depending on the specific board design. Up to 484 bytes of user-accessible OTP are available.

The initial state of all bits in an unprogrammed OTP device is 0. After any bit is programmed to a 1, it cannot be reprogrammed to 0.

The entire OTP array can be programmed in a single write cycle using a utility provided with the Cypress WLAN manufacturing test

tools. Alternatively, multiple write cycles can be used to selectively program specific bytes, but only bits which are still in the 0 state

can be altered during each programming cycle.

Prior to OTP programming, all values should be verified using the appropriate editable nvram.txt file, which is provided with the

reference board design package.

9.3 GPIO Interface

The CYW4356 has 11 general-purpose I/O (GPIO) pins in the WLAN section that can be used to connect to various external devices.

Upon power-up and reset, these pins become tristated. Subsequently, they can be programmed to be either input or output pins via

the GPIO control register. In addition, the GPIO pins can be assigned to various other functions, see Table 27.

9.4 External Coexistence Interface

An external handshake interface is available to enable signaling between the device and an external co-located wireless device, such

as GPS, LTE, or UWB, to manage wireless medium sharing for optimal performance.

Figure 27 and Figure 28 show the LTE coexistence interface (including UART) for each CYW4356 package type. See Table 27 for

CYW4356

9.5 UART Interface

One 2-wire UART interface can be enabled by software as an alternate function on GPIO pins. Refer to Table 27. Provided primarily

for debugging during development, this UART enables the CYW4356 to operate as RS-232 data termination equipment (DTE) for

exchanging and managing data with other serial devices. It is compatible with the industry standard 16550 UART, and provides a FIFO

size of 64 × 8 in each direction.

9.6 JTAG Interface

The CYW4356 supports the IEEE 1149.1 JTAG boundary scan standard for performing device package and PCB assembly testing

during manufacturing. In addition, the JTAG interface allows Cypress to assist customers by using proprietary debug and character-

ization test tools during board bring-up. Therefore, it is highly recommended to provide access to the JTAG pins by means of test

points or a header on all PCB designs.

Refer to Table 27 for JTAG pin assignments.

9.7 SPROM Interface

Various hardware configuration parameters may be stored in an external SPROM instead of the OTP. The SPROM is read by system

software after device reset. In addition, depending on the board design, customer-specific parameters may be stored in SPROM.

The four SPROM control signals —SPROM_CS, SPROM_CLK, SPROM_MI, and SPROM_MO are multiplexed on the SDIO interface

(see Table 27 for additional details). By default, the SPROM interface supports 2 Kbit serial SPROMs, and it can also support 4 Kbit

and 16 Kbit serial SPROMs by using the appropriate strapping option.

Note: The CYW4356 is backward compatible with SDIO v2.0 host interfaces.

The SDIO interface also has the ability to map the interrupt signal on to a GPIO pin for applications requiring an interrupt different

from the one provided by the SDIO interface. The ability to force control of the gated clocks from within the device is also provided.

SDIO mode is enabled by strapping options. Refer to Table 24 WLAN GPIO Functions and Strapping Options.

The following three functions are supported:

CYW4356

10.2 PCI Express Interface

The PCI Express (PCIe) core on the CYW4356 is a high-performance serial I/O interconnect that is protocol compliant and electrically

compatible with the PCI Express Base Specification v3.0 running at Gen1 speeds. This core contains all the necessary blocks,

including logical and electrical functional subblocks to perform PCIe functionality and maintain high-speed links, using existing PCI

system configuration software implementations without modification.

Organization of the PCIe core is in logical layers: Transaction Layer, Data Link Layer, and Physical Layer, as shown in Figure 31. A

configuration or link management block is provided for enumerating the PCIe configuration space and supporting generation and

reception of System Management Messages by communicating with PCIe layers.

Each layer is partitioned into dedicated transmit and receive units that allow point-to-point communication between the host and

CYW4356 device. The transmit side processes outbound packets whereas the receive side processes inbound packets. Packets are

formed and generated in the Transaction and Data Link Layer for transmission onto the high-speed links and onto the receiving device.

A header is added at the beginning to indicate the packet type and any other optional fields.

10.2.1 Transaction Layer Interface

The PCIe core employs a packet-based protocol to transfer data between the host and CYW4356 device, delivering new levels of

performance and features. The upper layer of the PCIe is the Transaction Layer. The Transaction layer is primarily responsible for

assembly and disassembly of Transaction Layer Packets (TLPs). TLP structure contains header, data payload, and End-to-End CRC

(ECRC) fields, which are used to communicate transactions, such as read and write requests and other events.

A pipelined full split-transaction protocol is implemented in this layer to maximize efficient communication between devices with credit-

based flow control of TLP, which eliminates wasted link bandwidth due to retries.

10.2.2 Data Link Layer

The data link layer serves as an intermediate stage between the transaction layer and the physical layer. Its primary responsibility is

to provide reliable, efficient mechanism for the exchange of TLPs between two directly connected components on the link. Services

provided by the data link layer include data exchange, initialization, error detection and correction, and retry services.

Data Link Layer Packets (DLLPs) are generated and consumed by the data link layer. DLLPs are the mechanism used to transfer link

management information between data link layers of the two directly connected components on the link, including TLP acknowl-

edgement, power management, and flow control.

Page 51 of 155

ADVANCE

CYW4356

10.2.3 Physical Layer

The physical layer of the PCIe provides a handshake mechanism between the data link layer and the high-speed signaling used for

Link data interchange. This layer is divided into the logical and electrical functional subblocks. Both subblocks have dedicated transmit

and receive units that allow for point-to-point communication between the host and CYW4356 device. The transmit section prepares

outgoing information passed from the data link layer for transmission, and the receiver section identifies and prepares received

information before passing it to the data link layer. This process involves link initialization, configuration, scrambler, and data

conversion into a specific format.

10.2.4 Logical Subblock

The logical sub block primary functions are to prepare outgoing data from the data link layer for transmission and identify received

data before passing it to the data link layer.

10.2.5 Scrambler/Descrambler

This PCIe PHY component generates pseudo-random sequence for scrambling of data bytes and the idle sequence. On the transmit

side, scrambling is applied to characters prior to the 8b/10b encoding. On the receive side, descrambling is applied to characters after

8b/10b decoding. Scrambling may be disabled in polling and recovery for testing and debugging purposes.

10.2.6 8B/10B Encoder/Decoder

The PCIe core on the CYW4356 uses an 8b/10b encoder/decoder scheme to provide DC balancing, synchronizing clock and data

recovery, and error detection. The transmission code is specified in the ANSI X3.230-1994, clause 11 and in IEEE 802.3z, 36.2.4.

Using this scheme, 8-bit data characters are treated as 3 bits and 5 bits mapped onto a 4-bit code group and a 6-bit code group,

respectively. The control bit in conjunction with the data character is used to identify when to encode one of the twelve Special Symbols

included in the 8b/10b transmission code. These code groups are concatenated to form a 10-bit symbol, which is then transmitted

serially. Special Symbols are used for link management, frame TLPs, and DLLPs, allowing these packets to be quickly identified and

easily distinguished.

10.2.7 Elastic FIFO

An elastic FIFO is implemented in the receiver side to compensate for the differences between the transmit clock domain and the

receive clock domain, with worse case clock frequency specified at 600 ppm tolerance. As a result, the transmit and receive clocks

can shift one clock every 1666 clocks. In addition, the FIFO adaptively adjusts the elastic level based on the relative frequency

difference of the write and read clock. This technique reduces the elastic FIFO size and the average receiver latency by half.

10.2.8 Electrical Subblock

The high-speed signals utilize the Common Mode Logic (CML) signaling interface with on-chip termination and de-emphasis for best-

in-class signal integrity. A de-emphasis technique is employed to reduce the effects of Intersymbol Interference (ISI) due to the

interconnect by optimizing voltage and timing margins for worst case channel loss. This results in a maximally open “eye” at the

detection point, thereby allowing the receiver to receive data with acceptable Bit-Error Rate (BER).

To further minimize ISI, multiple bits of the same polarity that are output in succession are de-emphasized. Subsequent same bits are

reduced by a factor of 3.5 dB in power. This amount is specified by PCIe to allow for maximum interoperability while minimizing the

complexity of controlling the de-emphasis values. The high-speed interface requires AC coupling on the transmit side to eliminate the

DC common mode voltage from the receiver. The range of AC capacitance allowed is 75 nF to 200 nF.

10.2.9 Configuration Space

The PCIe function in the CYW4356 implements the configuration space as defined in the PCI Express Base Specification v3.0.

zation. The architecture diagram of the MAC is shown in Figure 32.

CYW4356

PSM

The programmable state machine (PSM) is a micro-coded engine, which provides most of the low-level control to the hardware, to

implement the IEEE 802.11 specification. It is a microcontroller that is highly optimized for flow control operations, which are predom-

inant in implementations of communication protocols. The instruction set and fundamental operations are simple and general, which

allows algorithms to be optimized until very late in the design process. It also allows for changes to the algorithms to track evolving

IEEE 802.11 specifications.

The PSM fetches instructions from the microcode memory. It uses the shared memory to obtain operands for instructions, as a data

store, and to exchange data between both the host and the MAC data pipeline (via the SHM bus). The PSM also uses a scratchpad

memory (similar to a register bank) to store frequently accessed and temporary variables.

The PSM exercises fine-grained control over the hardware engines, by programming internal hardware registers (IHR). These IHRs

are co-located with the hardware functions they control, and are accessed by the PSM via the IHR bus.

The PSM fetches instructions from the microcode memory using an address determined by the program counter, instruction literal,

or a program stack. For ALU operations the operands are obtained from shared memory, scratchpad, IHRs, or instruction literals, and

the results are written into the shared memory, scratchpad, or IHRs.

There are two basic branch instructions: conditional branches and ALU based branches. To better support the many decision points

in the IEEE 802.11 algorithms, branches can depend on either a readily available signals from the hardware modules (branch condition

signals are available to the PSM without polling the IHRs), or on the results of ALU operations.

WEP

The wired equivalent privacy (WEP) engine encapsulates all the hardware accelerators to perform the encryption and decryption, and

MIC computation and verification. The accelerators implement the following cipher algorithms: legacy WEP, WPA TKIP, WPA2 AES-

CCMP.

The PSM determines, based on the frame type and association information, the appropriate cipher algorithm to be used. It supplies

the keys to the hardware engines from an on-chip key table. The WEP interfaces with the TXE to encrypt and compute the MIC on

transmit frames, and the RXE to decrypt and verify the MIC on receive frames.

TXE

The transmit engine (TXE) constitutes the transmit data path of the MAC. It coordinates the DMA engines to store the transmit frames

in the TXFIFO. It interfaces with WEP module to encrypt frames, and transfers the frames across the MAC-PHY interface at the

appropriate time determined by the channel access mechanisms.

The data received from the DMA engines are stored in transmit FIFOs. The MAC supports multiple logical queues to support traffic

streams that have different QoS priority requirements. The PSM uses the channel access information from the IFS module to schedule

a queue from which the next frame is transmitted. Once the frame is scheduled, the TXE hardware transmits the frame based on a

precise timing trigger received from the IFS module.

The TXE module also contains the hardware that allows the rapid assembly of MPDUs into anA-MPDU for transmission. The hardware

module aggregates the encrypted MPDUs by adding appropriate headers and pad delimiters as needed.

RXE

The receive engine (RXE) constitutes the receive data path of the MAC. It interfaces with the DMAengine to drain the received frames

from the RXFIFO. It transfers bytes across the MAC-PHY interface and interfaces with the WEP module to decrypt frames. The

decrypted data is stored in the RXFIFO.

The RXE module contains programmable filters that are programmed by the PSM to accept or filter frames based on several criteria

such as receiver address, BSSID, and certain frame types.

The RXE module also contains the hardware required to detect A-MPDUs, parse the headers of the containers, and disaggregate

them into component MPDUS.

IFS

The IFS module contains the timers required to determine interframe space timing including RIFS timing. It also contains multiple

backoff engines required to support prioritized access to the medium as specified by WMM.

The interframe spacing timers are triggered by the cessation of channel activity on the medium, as indicated by the PHY. These timers

provide precise timing to the TXE to begin frame transmission. The TXE uses this information to send response frames or perform

transmit frame-bursting (RIFS or SIFS separated, as within a TXOP).

The backoff engines (for each access category) monitor channel activity, in each slot duration, to determine whether to continue or

pause the backoff counters. When the backoff counters reach 0, the TXE gets notified, so that it may commence frame transmission.

In the event of multiple backoff counters decrementing to 0 at the same time, the hardware resolves the conflict based on policies

provided by the PSM.

The IFS module also incorporates hardware that allows the MAC to enter a low-power state when operating under the IEEE power

save mode. In this mode, the MAC is in a suspended state with its clock turned off. A sleep timer, whose count value is initialized by

the PSM, runs on a slow clock and determines the duration over which the MAC remains in this suspended state. Once the timer

expires the MAC is restored to its functional state. The PSM updates the TSF timer based on the sleep duration ensuring that the TSF

is synchronized to the network.

The IFS module also contains the PTA hardware that assists the PSM in Bluetooth coexistence functions.

TSF

The timing synchronization function (TSF) module maintains the TSF timer of the MAC. It also maintains the target beacon trans-

mission time (TBTT). The TSF timer hardware, under the control of the PSM, is capable of adopting timestamps received from beacon

and probe response frames in order to maintain synchronization with the network.

The TSF module also generates trigger signals for events that are specified as offsets from the TSF timer, such as uplink and downlink

transmission times used in PSMP.

NAV

The network allocation vector (NAV) timer module is responsible for maintaining the NAV information conveyed through the duration

field of MAC frames. This ensures that the MAC complies with the protection mechanisms specified in the standard.

The hardware, under the control of the PSM, maintains the NAV timer and updates the timer appropriately based on received frames.

This timing information is provided to the IFS module, which uses it as a virtual carrier-sense indication.

MAC-PHY Interface

The MAC-PHY interface consists of a data path interface to exchange RX/TX data from/to the PHY. In addition, there is an

programming interface, which can be controlled either by the host or the PSM to configure and control the PHY.

11.2 IEEE 802.11ac Draft PHY

The CYW4356 WLAN Digital PHY is designed to comply with IEEE 802.11ac Draft and IEEE 802.11a/b/g/n dual-stream specifications

to provide wireless LAN connectivity supporting data rates from 1 Mbps to 866.7 Mbps for low-power, high-performance handheld

applications.

The PHY has been designed to work in the presence of interference, radio nonlinearity, and various other impairments. It incorporates

optimized implementations of the filters, FFT and Viterbi decoder algorithms. Efficient algorithms have been designed to achieve

maximum throughput and reliability, including algorithms for carrier sense/rejection, frequency/phase/timing acquisition and tracking,

channel estimation and tracking. The PHY receiver also contains a robust IEEE 802.11b demodulator. The PHY carrier sense has

been tuned to provide high throughput for IEEE 802.11g/11b hybrid networks with Bluetooth coexistence. It has also been designed

for sharing an antenna between WL and BT to support simultaneous RX-RX.

The key PHY features include:

■ Programmable data rates from MCS0–15 in 20 MHz, 40 MHz, and 80 MHz channels, as specified in IEEE 802.11ac Draft

■ Supports Optional Short GI and Green Field modes in TX and RX

■ TX and RX LDPC for improved range and power efficiency

■ Beamforming support

■ All scrambling, encoding, forward error correction, and modulation in the transmit direction and inverse operations in the receive

direction.

■ Supports IEEE 802.11h/k for worldwide operation

■ Advanced algorithms for low power, enhanced sensitivity, range, and reliability

12. WLAN Radio Subsystem

The CYW4356 includes an integrated dual-band WLAN RF transceiver that has been optimized for use in 2.4 GHz and 5 GHz Wireless

LAN systems. It has been designed to provide low-power, low-cost, and robust communications for applications operating in the

globally available 2.4 GHz unlicensed ISM or 5 GHz U-NII bands. The transmit and receive sections include all on-chip filtering, mixing,

and gain control functions.

Sixteen RF control signals are available (eight per core) to drive external RF switches and support optional external power amplifiers

and low-noise amplifiers for each band. See the reference board schematics for further details.

A block diagram of the radio subsystem (core 0) is shown in Figure 34. Core 1, is identical to Core 0 without the Bluetooth blocks.

Note that integrated on-chip baluns (not shown) convert the fully differential transmit and receive paths to single-ended signal pins.

12.1 Receiver Path

The CYW4356 has a wide dynamic range, direct conversion receiver that employs high order on-chip channel filtering to ensure

reliable operation in the noisy 2.4 GHz ISM band or the entire 5 GHz U-NII band. An on-chip low noise amplifier (LNA) in the 2.4 GHz

path in core 0 is shared between the Bluetooth and WLAN receivers, whereas the 5 GHz receive path and the core 1 2.4 GHz receive

path have dedicated on-chip LNAs. Control signals are available that can support the use of external LNAs for each band, which can

increase the receive sensitivity by several dB.

12.2 Transmit Path

Baseband data is modulated and upconverted to the 2.4 GHz ISM or 5 GHz U-NII bands, respectively. Linear on-chip power amplifiers

are included, which are capable of delivering high output power while meeting IEEE 802.11ac and IEEE 802.11a/b/g/n specifications,

and without the need for external PAs. When using the internal PAs, closed-loop output power control is completely integrated.

12.3 Calibration

The CYW4356 features dynamic and automatic on-chip calibration to continually compensate for temperature and process variations

across components. These calibration routines are performed periodically in the course of normal radio operation. Examples of some

of the automatic calibration algorithms are baseband filter calibration for optimum transmit and receive performance, and LOFT

calibration for carrier leakage reduction. In addition, I/Q Calibration, R Calibration, and VCO Calibration are performed on-chip. No

per-board calibration is required in manufacturing test, which helps to minimize the test time and cost in large volume production.

13.4 WLAN/BT GPIO Signals and Strapping Options

The pins listed in Table 24 and Table 25 are sampled at power-on reset (POR) to determine the various operating modes. Sampling

occurs a few milliseconds after an internal POR or deassertion of the external POR. After the POR, each pin assumes the GPIO or

alternative function specified in the signal descriptions table. Each strapping option pin has an internal pull-up (PU) or pull-down (PD)

resistor that determines the default mode. To change the mode, connect an external PU resistor to VDDIO or a PD resistor to GND,

using a 10 kΩ resistor or less.

Note: Refer to the reference board schematics for more information.

CYW4356

21. Power-Up Sequence and Timing

21.1 Sequencing of Reset and Regulator Control Signals

The CYW4356 has two signals that allow the host to control power consumption by enabling or disabling the Bluetooth, WLAN, and

internal regulator blocks. These signals are described below. Additionally, diagrams are provided to indicate proper sequencing of the

signals for various operational states (see Figure 47, Figure 48, and Figure 49 and Figure 50). The timing values indicated are

minimum required values; longer delays are also acceptable.

21.1.1 Description of Control Signals

■ WL_REG_ON: Used by the PMU to power up the WLAN section. It is also OR-gated with the BT_REG_ON input to control the

internal CYW4356 regulators. When this pin is high, the regulators are enabled and the WLAN section is out of reset. When this

pin is low the WLAN section is in reset. If both the BT_REG_ON and WL_REG_ON pins are low, the regulators are disabled.

■ BT_REG_ON: Used by the PMU (OR-gated with WL_REG_ON) to power up the internal CYW4356 regulators. If both the

BT_REG_ON and WL_REG_ON pins are low, the regulators are disabled. When this pin is low and WL_REG_ON is high, the BT

section is in reset.

Note:

■ For both the WL_REG_ON and BT_REG_ON pins, there should be at least a 10 ms time delay between consecutive toggles (where

both signals have been driven low). This is to allow time for the CBUCK regulator to discharge. If this delay is not followed, then

there may be a VDDIO in-rush current on the order of 36 mA during the next PMU cold start.

■ The reset requirements for the Bluetooth core are also applicable for the FM core. In other words, if FM is to be used, then the

Bluetooth core must be enabled.

■ The CYW4356 has an internal power-on reset (POR) circuit. The device will be held in reset for a maximum of 110 ms after VDDC

and VDDIO have both passed the POR threshold. Wait at least 150 ms after VDDC and VDDIO are available before initiating SDIO

accesses.

■ VBAT should not rise 10%–90% faster than 40 microseconds. VBAT should be up before or at the same time as VDDIO. VDDIO

should NOT be present first or be held high before VBAT is high.

22. Package Information

22.1 Package Thermal Characteristics

The information in Table 63 and Table 64 is based on the following conditions:

■ No heat sink, T_A= 70°C. This is an estimate, based on a 4-layer PCB that conforms to EIA/JESD51–7

(101.6 mm × 101.6 mm × 1.6 mm) and P = 1.53W continuous dissipation.

■ Absolute junction temperature limits are maintainedthrough active thermal monitoring and driver-based techniques that mayinclude

duty-cycle limiting or turning off one of the TX chains, or both.

22.2 Junction Temperature Estimation and PSI Versus Theta

JT

JC

The package thermal characterization parameter PSI_JT(_JT) yields a better estimation of actual junction temperature (T_J) than using

the junction-to-case thermal resistance parameter Theta_JC(_JC). The reason for this is that _JCis based on the assumption that all

the power is dissipated through the top surface of the package case. In actual applications, however, some of the power is dissipated

through the bottom and sides of the package. _JTtakes into account the power dissipated through the top, bottom, and sides of the

package. The equation for calculating the device junction temperature is:

T_J= T_T+ P x _JT

Where:

■ T_J= Junction temperature at steady-state condition (°C)

■ T_T= Package case top center temperature at steady-state condition (°C)

■ P = Device power dissipation (Watts)

■ _JT= Package thermal characteristics; no airflow (°C/W)
