CYW4354
Single-Chip 5G Wi-Fi IEEE 802.11ac 2×2 MAC/Baseband/Radio
with Integrated Bluetooth 4.1 and FM Receiver
The Cypress CYW4354 is a complete dual–band (2.4 GHz and 5 GHz) 5G Wi–Fi 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. 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, a high-speed inter-chip (HSIC) interface, 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 CYW4354 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 CYW4354 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.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion,
there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides
Cypress ordering part number that matches an existing IoT part number.

CYW4354
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 CYW4354. 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 CYW4354.
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 CYW4354 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
CYW4354 with all the voltages it requires, further reducing leakage currents.

CYW4354
2.3 WLAN Power Management
The CYW4354 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 CYW4354 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 CYW4354 includes an advanced WLAN power management
unit (PMU) sequencer. The PMU sequencer provides significant power savings by putting the CYW4354 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 CYW4354 WLAN power states are described as follows:
■ Active mode— All WLAN blocks in the CYW4354 are powered up and fully functional with active carrier sensing and frame trans-
mission 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, orTCXO) 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 resume through the HSIC
or SDIO bus, 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 CYW4354 is effectively powered off by shutting down all internal regulators. The chip is brought out of
this mode by external logic re-enabling 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.

CYW4354
2.5 Power-Off Shutdown
The CYW4354 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 CYW4354 is not needed in the system, VDDIO_RF and VDDC are shut down while
VDDIO remains powered. This allows the CYW4354 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 CYW4354, 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 CYW4354 to be fully integrated in an embedded device and
take full advantage of the lowest power-savings modes.
When the CYW4354 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 CYW4354 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
Power-Up Sequence and Timing on page 153.
Table 3. Power-Up/Power-Down/Reset Control Signals
Signal
Description
WL_REG_ON
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 CYW4354 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 kΩ 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 CYW4354
regulators. If BT_REG_ON and WL_REG_ON are low, the regulators will be disabled. This pin has an internal
200 kΩ pull-down resistor that is enabled by default. It can be disabled through programming.

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 CYW4354 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 4. Consult the reference schematics for the latest configuration.

A fractional-N synthesizer in the CYW4354 generates the radio frequencies, clocks, and data/packet timing, enabling it to operate
using a wide selection of frequency references.
For SDIO, HSIC, and PCIe WLAN host applications, the recommended default frequency reference is a 37.4 MHz crystal. For PCIe
applications, see Table 4 on page 15 for details on alternatives for the external frequency reference. The signal characteristics for the
crystal oscillator interface are also listed in Table 4.
For SDIO WLAN host applications, the recommended default frequency reference is a 37.4 MHz crystal. 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 Broadcom for further details.

3.2 External Frequency Reference
For operation in SDIO and HSIC modes only, an alternative to a crystal (an external precision frequency reference) can be used. The
recommended 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 5. The internal clock buffer connected to this pin will be turned OFF when the CYW4354 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 CYW4354 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
Table 5.

CYW4354
4. Bluetooth + FM Subsystem Overview
The Cypress CYW4354 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 CYW4354 is the optimal solution for any Bluetooth voice and/or data application that also requires an FM radio receiver. The

4.2 Bluetooth Radio
The CYW4354 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 CYW4354 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: 002-14809 Rev. *J
Page 19 of 165
CYW4354
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 CYW4354 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 CYW4354 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 CYW4354 uses an
internal RF and IF loop filter.
4.2.9 Calibration
The CYW4354 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.
■ SniffSubrating(SSR):Optimizespowerconsumptionforlowduty cycleasymmetricdataflow, whichsubsequentlyextendsbattery 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354
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 CYW4354 may be configured so that dedicated signals are used for power management hand-
shaking between the CYW4354 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.

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 CYW4354 runs on the low-power
oscillator and wakes up after a predefined time period.
■ Alow-powershutdownfeatureallowsthedevicetobeturnedoffwhilethehostandanyotherdevicesinthesystemremainoperational.
When the CYW4354 is not needed in the system, the RF and core supplies are shut down while the I/O remains powered. This
allows the CYW4354 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 CYW4354, 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 CYW4354 to
be fully integrated in an embedded device to take full advantage of the lowest power-saving modes.
Two CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 provides support for wideband speech (WBS) using on-chip SmartAudio technology. The CYW4354 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 CYW4354 uses a proprietary waveform extension algorithm
to provide dramatic improvement in the audio quality. Figure 7 and Figure 8 show audio waveforms with and without Packet Loss
Concealment. Broadcom PLC/BEC algorithms also support wide band speech.

5.5.7 Audio Rate-Matching Algorithms
The CYW4354 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 CYW4354 can support SBC and mSBC encoding and decoding for wideband speech.
5.5.9 Multiple Simultaneous A2DP Audio Stream
The CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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.

CYW4354
5.7 Advanced Bluetooth/WLAN Coexistence
The CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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
CYW4354. 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 the BT_HOST_WAKE (BT_GPIO1) pin is pulled low by an external pull-down during power-up, it selects the SPI transport interface.
■ 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.
7.3 PCM Interface
The CYW4354 supports two independent PCM interfaces that share the pins with the I2S interfaces. The PCM Interface on the
CYW4354 can connect to linear PCM Codec devices in master or slave mode. In master mode, the CYW4354 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 CYW4354.
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 CYW4354 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 CYW4354 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.

Page 29 of 165
CYW4354
7.3.3 Data Formatting
The CYW4354 may be configured to generate and accept several different data formats. For conventional narrowband speech mode,
the CYW4354 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 CYW4354 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 CYW4354 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 9 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 wake-up
■ Bluetooth HCI
■ HID, DFU, UHE (proprietary method to emulate an HID device at system bootup)
■ Integrated detach resistor
7.4.2 Operation
The CYW4354 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 16).
Figure 16. USB Compounded Device Configuration
Host
USB Compounded Device

USB Device 3
Bluetooth
Depending on the desired hub mode configuration, the CYW4354 can boot up showing the three ports connected to logical USB
devices internal to the CYW4354: 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 Broadcom 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 CYW4354 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
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.
Interface 1
Interface 2
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.

CYW4354
7.4.3 USB Hub and UHE Support
The CYW4354 supports the USB hub and device model (USB, Revision 2.0, full-speed compliant). Optional mouse and keyboard
devices utilize Broadcom’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 CYW4354 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 CYW4354 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 16 on page 37)
supports up to three downstream ports. This configuration can also be programmed to a single USB device core. The device automat-
ically 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.
7.4.4 USB Full-Speed Timing

CYW4354
7.5 UART Interface
The CYW4354 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 4.1 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 CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 Ttr and Tr because 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, tHC and tLC
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 0.35Tr, any clock that meets the requirements can be used.
d. Because the delay (tdtr) and the maximum transmitter speed (defined by Ttr) are related, a fast transmitter driven by a slow clock edge can
result in tdtr not exceeding tRC which means thtr becomes zero or negative. Therefore, the transmitter has to guarantee that thtr is greater than
or equal to zero, so long as the clock rise-time tRC is not more than tRCmax, where tRCmax is not less than 0.15Ttr.
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.
Note: The time periods specified in Figure 19 and Figure 20 are defined by the transmitter speed. The receiver specifications must
match transmitter performance.

CYW4354
8. FM Receiver Subsystem
8.1 FM Radio
The CYW4354 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 CYW4354 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 CYW4354 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 CYW4354 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 Wide Band 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
CYW4354 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 CYW4354 supports a number of FM search and tune functions that allows the host to implement many convenient user functions,
which are accessed through the Broadcom 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.
■ AlternateFrequencyJump:AllowstheFMreceivertoautomaticallyjumptoanalternateFMchannelthatcarriesthesameinformation,
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.

CYW4354
8.8 Audio Features
A number of features are implemented in the CYW4354 to provide the best possible audio experience for the user.
■ Mono/Stereo Blend or Switch: The CYW4354 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 21, 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. Broadcom static suppression
typically gives a static-free user experience to within 3 dB of ultimate sensitivity.
Figure 21. Example Blend/Switch Usage
❐ 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 22, the switch point is programmed to switch to mono to maintain a 40 dB SNR.
Document Number: 002-14809 Rev. *J
Page 45 of 165
CYW4354
Figure 22. 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 23.
Figure 23. Example Soft Mute Characteristic
Document Number: 002-14809 Rev. *J
Page 46 of 165
CYW4354
■ 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 CYW4354 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 CYW4354 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 CYW4354 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 pre-emphasis

9. WLAN Global Functions
9.1 WLAN CPU and Memory Subsystem
The CYW4354 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 Broadcom 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 CYW4354 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 on page 97.

CYW4354
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, or LTE, to manage wireless medium sharing for optimal performance.
Figure 24 and Figure 25 on page 49 show the LTE coexistence interface (including UART) for each CYW4354 package type. See
Table 27 on page 97 for further details on multiplexed signals, such as the GPIO pins.

CYW4354
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 on page 97. Provided
primarily for debugging during development, this UART enables the CYW4354 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 CYW4354 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 Broadcom to assist customers by using proprietary debug and charac-
terization 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 on page 97 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 on page 97 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.
9.8 SFLASH Interface
For use only when the HSIC interface mode is selected, an interface to external SFLASH is available.
The four SFLASH control signals —SFLASH_CS#, SFLASH_CLK, SFLASH_MI, and SFLASH_MO are multiplexed on the SDIO
interface (see Table 27 on page 97 for additional details).

10. WLAN Host Interfaces
10.1 SDIO v3.0
All three package options of the CYW4354 WLAN section provide support for SDIO version 3.0, including the new UHS-I modes:
■ DS: Default speed (DS) up to 25 MHz, including 1- and 4-bit modes (3.3V signaling).

■ DDR50: DDR up to 50 MHz (1.8V signaling).
Note: The CYW4354 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 on page 96 WLAN GPIO Functions and Strapping Options.
The following three functions are supported:
■ Function 0 Standard SDIO function (max. BlockSize/ByteCount = 32B)

10.2 HSIC Interface
As an alternative to SDIO, an HSIC host interface can be enabled using the strapping option pins strap_host_ifc_[3:1]. HSIC is a
simplified derivative of the USB2.0 interface designed to replace a standard USB PHY and cable for short distances (up to 10 cm) on
board point-to-point connections. Using two signals, a bidirectional data strobe (STROBE) and a bidirectional DDR data signal (DATA),
it provides high-speed serial 480 Mbps data transfers that are 100% host driver compatible with traditional USB 2.0 cable-connected
topologies.
Figure 28 shows the blocks in the HSIC device core.
Key features of HSIC include:
■ High-speed 480 Mbps data rate
■ Source-synchronous serial interface using 1.2V LVCMOS signal levels
■ No power consumed except when a data transfer is in progress
■ Maximum trace length of 10 cm.
■ No Plug-n-Play support, no hot attach/removal

10.3 PCI Express Interface
The PCI Express (PCIe™) core on the CYW4354 is a high-performance serial I/O interconnect that is protocol compliant and electri-
cally 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 29. 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
CYW4354 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.

10.3.1 Transaction Layer Interface
The PCIe core employs a packet-based protocol to transfer data between the host and CYW4354 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.
10.3.2 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.
10.3.3 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 CYW4354 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.
10.3.4 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.
10.3.5 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.
Document Number: 002-14809 Rev. *J
Page 54 of 165
CYW4354
10.3.6 8B/10B Encoder/Decoder
The PCIe core on the CYW4354 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.
10.3.7 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.
10.3.8 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.
10.3.9 Configuration Space
The PCIe function in the CYW4354 implements the configuration space as defined in the PCI Express Base Specification v3.0.

11.1 IEEE 802.11ac Draft MAC
The CYW4354 WLAN MAC is designed to support high-throughput operation with low-power consumption. It does so without compro-
mising the Bluetooth coexistence policies, thereby enabling optimal performance over both networks. In addition, several power saving
modes have been implemented that allow the MAC to consume very little power while maintaining network-wide timing synchroni-
zation. The architecture diagram of the MAC is shown in Figure 30.
The following sections provide an overview of the important modules in the MAC.

11.1.1 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.
11.1.2 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.

CYW4354
11.1.3 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.
11.1.4 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.
11.1.5 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.
11.1.6 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.
11.1.7 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.
11.1.8 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.

12. WLAN Radio Subsystem
The CYW4354 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 32 on page 62. Core 1, is identical to Core 0 without the Bluetooth
blocks. The integrated on-chip baluns (not shown) convert the fully differential transmit and receive paths to single-ended signal pins.
12.1 Receiver Path
The CYW4354 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 CYW4354 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 kꢀ resistor or less.
Note: Refer to the reference board schematics for more information.

a. Keeper column: N = pad has no keeper. Y = pad has a keeper. Keeper is always active except in Power-down state. If there is no keeper, and it is an input and there is Nopull, then the
pad should be driven to prevent leakage due to floating pad (SDIO_CLK, for example).
b. In the Power-down state (xx_REG_ON=0): High-Z; NoPull => the pad is disabled because power is not supplied.
c. Depending on whether the PCM interface is enabled and the configuration of PCM is in master or slave mode, it can be either input or output.
d. Depending on whether the I2S interface is enabled and the configuration of I2S is in master or slave mode, it can be either input or output.
e. For WLBGA this GPIO has NoPull in this state. For WLCSP this GPIO has a PU in this state.

21. Power-Up Sequence and Timing
21.1 Sequencing of Reset and Regulator Control Signals
The CYW4354 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 46, Figure 47 on page 154, and Figure 48 and Figure 49 on page 155). 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 CYW4354 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 CYW4354 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 CYW4354 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, TA = 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 maintained through active thermal monitoring and driver-based techniques that may include
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 PSIJT (JT) yields a better estimation of actual junction temperature (TJ) than using
the junction-to-case thermal resistance parameter ThetaJC (θJC). The reason for this is that θJC is 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. JT takes into account the power dissipated through the top, bottom, and sides of the
package. The equation for calculating the device junction temperature is:
T = T + P x
J
T
JT
Where:
■ TJ = Junction temperature at steady-state condition (°C)
■ TT = Package case top center temperature at steady-state condition (°C)
■ P = Device power dissipation (Watts)
■ JT = Package thermal characteristics; no airflow (°C/W)
