CYW43340  
Single-Chip, Dual-Band (2.4 GHz/5 GHz) IEEE 802.11 a/b/g/n  
MAC/Baseband/Radio with Integrated Bluetooth 4.0  
General Description  
The Cypress CYW43340 single–chip quad–radio device provides the highest level of integration for wearables, Internet of Things and  
gateway applications, with integrated dual band (2.4 GHz / 5 GHz) IEEE 802.11 a/b/g and single–stream IEEE 802.11n MAC/  
baseband/radio, and Bluetooth 4.0. The CYW43340 includes integrated power amplifiers and LNAs for the 2.4 GHz and 5 GHz WLAN  
bands, and an integrated 2.4 GHz T/R switch. This greatly reduces the external part count, PCB footprint, and cost of the solution.  
Using advanced design techniques and process technology to reduce active and idle power, the CYW43340 is designed to address  
the needs of mobile devices that require minimal power consumption and compact size. It includes a power management unit which  
simplifies the system power topology and allows for operation directly from a mobile platform battery while maximizing battery life.  
The CYW43340 implements the highly sophisticated Enhanced Collaborative Coexistence algorithms and hardware mechanisms,  
allowing for an extremely collaborative Bluetooth coexistence scheme along with coexistence support for external radios (such as  
cellular and LTE, GPS, WiMAX, and Ultra–Wideband) and a single shared 2.4 GHz antenna for Bluetooth and WLAN. As a result,  
enhanced overall quality for simultaneous voice, video, and data transmission in an IoT or wearable application is achieved.  
For the WLAN section, two host interface options are included: an SDIO v2.0 interface and a High-Speed Inter-Chip (HSIC) interface  
(a USB 2.0 derivative for short-distance on-board connections). An independent, high-speed UART is provided for the Bluetooth host  
interface.  
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.

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 CYW43340. All regulators  
are programmable via the PMU. These blocks simplify power supply design for Bluetooth, and WLAN in embedded designs.  
A single VBAT (2.9–4.8V) and VIO supply (1.8V to 3.3V) can be used, with all additional voltages being provided by the regulators in  
the CYW43340.  
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 CYW43340 allows for an extremely low power-consumption mode by completely shutting down the CBUCK, CLDO, and LNDLO  
regulators. When in this state, LPLDO1 and LPLDO2 (which are low-power linear regulators that are supplied by the system VIO  
supply) provide the CYW43340 with all the voltages it requires, further reducing leakage currents.

CYW43340  
2.2 WLAN Power Management  
The CYW43340 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 CYW43340 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 CYW43340 includes an advanced WLAN power  
management unit (PMU) sequencer. The PMU sequencer provides significant power savings by putting the CYW43340 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 CYW43340 WLAN power states are described as follows:  
Active mode— All WLAN blocks in the CYW43340 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.  
Doze mode—The radio, analog domains, and most of the linear regulators are powered down. The rest of the CYW43340 remains  
powered up in an IDLE state. 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. In Doze mode, the primary power consumed is due to leakage current.  
Deep-sleep mode—Most of the chip including both analog and digital domains and most of the regulators are powered off. 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 re-initialization.  
Power-down mode—The CYW43340 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.  
2.3 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 Resource Min  
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:  
1. Computes the required resource set based on requests and the resource dependency table.  
2. 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.  
3. Compares the request with the current resource status and determines which resources must be enabled or disabled.  
4. Initiates a disable sequence for each resource that is enabled, no longer being requested, and has no powered up dependents.  
5. Initiates an enable sequence for each resource that is disabled, is being requested, and has all of its dependencies enabled.

CYW43340  
2.4 Power-Off Shutdown  
The CYW43340 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 CYW43340 is not needed in the system, VDDIO_RF and VDDC are shut down while  
VDDIO remains powered. This allows the CYW43340 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 CYW43340, 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 CYW43340 to be fully integrated in an embedded device and  
take full advantage of the lowest power-savings modes.  
Two signals on the CYW43340, the frequency reference input (WRF_XTAL_CAB_OP) and the LPO_IN input, are designed to be high-  
impedance inputs that do not load down the driving signal even if the chip does not have VDDIO power applied to it.  
When the CYW43340 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.  
2.5 Power-Up/Power-Down/Reset Circuits  
The CYW43340 has two signals (see Table 2) 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 19.: “Power-Up Sequence and Timing,” on page 87.  
Table 2. 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 CYW43340 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 kpull-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  
CYW43340 regulators. If BT_REG_ON and WL_REG_ON are low, the regulators will be disabled. This pin has  
an internal 200 kpull-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 driven by a temperature-compensated crystal oscillator (TCXO) signal may be used. In addition, a low-power oscillator  
(LPO) is provided for lower power mode timing.  
Note: The crystal and TCXO implementations have different power supplies (WRF_XTAL_VDD1P2 for crystal,  
WRF_TCXO_VDD for TCXO).  
3.1 Crystal Interface and Clock Generation  
The CYW43340 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.

schematics for details.  
A fractional-N synthesizer in the CYW43340 generates the radio frequencies, clocks, and data/packet timing, enabling it to operate  
using a wide selection of frequency references.  
For SDIO and HSIC applications the default frequency reference is a 37.4 MHz crystal or TCXO. The signal characteristics for the  
crystal interface are listed in Table 3 on page 12.  
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 TCXO  
As an alternative to a crystal, an external precision TCXO can be used as the frequency reference, provided that it meets the Phase  
Noise requirements listed in Table 3. When the clock is provided by an external TCXO, there are two possible connection methods,  
as shown in Figure 5 and Figure 6:  
1. If the TCXO is dedicated to driving the CYW43340, it should be connected to the WRF_XTAL_OP 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 CYW43340  
goes into sleep mode. When the clock buffer turns ON and OFF there will be a small impedance variation. If the TCXO is to be  
shared with another device, such as a GPS receiver, and impedance variation is not allowed, a dedicated external clock buffer will  
be needed. Power must be supplied to the WRF_XTAL_VDD1P2 pin.  
2. For 2.4 GHz operation only, an alternative is to DC-couple the TCXO to the WRF_TCXO_CK pin, as shown in Figure 6. Use this  
method when the same TCXO is shared with other devices and a change in the input impedance is not acceptable because it may  
cause a frequency shift that cannot be tolerated by the other device sharing the TCXO. This pin is connected to a clock buffer  
powered from WRF_TCXO_VDD. If the power supply to this buffer is always on (even in sleep mode), the clock buffer is always  
on, thereby ensuring a constant input impedance in all states of the device. The maximum current drawn from WRF_TCXO_VDD  
is approximately 500 µA.

e. The frequency step size is approximately 80 Hz resolution.  
f. The crystal should be capable of handling a 200uW drive level from the CYW43340.  
3.3 Frequency Selection  
Any frequency within the ranges specified for the crystal and TCXO reference may be used. These include not only the standard  
handset reference frequencies of 19.2, 19.44, 19.68, 19.8, 20, 26, 37.4, and 52 MHz, but also other frequencies in this range, with  
approximately 80 Hz resolution. The CYW43340 must have the reference frequency set correctly in order for any of the UART or PCM  
interfaces to function correctly, since all bit timing is derived from the reference frequency.  
Note: The fractional-N synthesizer can support many reference frequencies. However, frequencies other than the default  
require support to be added in the driver plus additional, extensive system testing. Contact Cypress for further details.  
The reference frequency for the CYW43340 may be set in the following ways:  
Set the xtalfreq=xxxxx parameter in the nvram.txt file (used to load the driver) to correctly match the crystal frequency.  
Auto-detect any of the standard handset reference frequencies using an external LPO clock.  
For applications such as handsets and portable smart communication devices, where the reference frequency is one of the standard  
frequencies commonly used, the CYW43340 automatically detects the reference frequency and programs itself to the correct  
reference frequency. In order for auto frequency detection to work correctly, the CYW43340 must have a valid and stable 32.768 kHz  
LPO clock that meets the requirements listed in Table 4 on page 14 and is present during power-on reset.

3.4 External 32.768 kHz Low-Power Oscillator  
The CYW43340 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, a trade-off caused by this wide LPO tolerance is a small current  
consumption increase during WLAN power save mode that is incurred by the need to wake up earlier to avoid missing beacons.  
Whenever possible, the preferred approach for WLAN is to use a precision external 32.768 kHz clock that meets the requirements  
listed in Table 4.  
Note: BT operations require the use of an external LPO that meets the requirements listed in Table 4.

CYW43340  
4.2 Bluetooth Radio  
The CYW43340 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 CYW43340 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 transmitted 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.  
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 CYW43340 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 CYW43340 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 CYW43340 uses an  
internal RF and IF loop filter.  
4.2.9 Calibration  
The CYW43340 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/ACL TX/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 4.0 Features  
The BBC supports all Bluetooth 4.0 features, with the following benefits:  
Dual-mode classic Bluetooth and classic Low Energy (BT and BLE) operation.  
Low Energy Physical Layer  
Low Energy Link Layer  
Enhancements to HCI for Low Energy  
Low Energy Direct Test mode  
AES encryption  
Note: The CYW43340 is compatible with the Bluetooth Low Energy operating mode, which provides a dramatic  
reduction in the power consumption of the Bluetooth radio and baseband. The primary application for this mode is to  
provide support for low data rate devices, such as sensors and remote controls.  
5.2 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.

The CYW43340 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 CYW43340 also supports enhanced testing features to simplify RF debugging  
and qualification and type-approval testing. These features include:  
Fixed frequency carrier wave (unmodulated) transmission

5.4 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 CYW43340  
are:  
RF Power Management  
Host Controller Power Management  
BBC Power Management  
5.4.1 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.  
5.4.2 Host Controller Power Management  
When running in UART mode, the CYW43340 may be configured so that dedicated signals are used for power management hand-  
shaking between the CYW43340 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 5 describes the power-control hand-shake signals used with the UART interface.

5.4.3 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 CYW43340 runs on the low-power  
oscillator and wakes up after a predefined time period.  
Alow-powershutdownfeatureallowsthedevicetobeturnedoffwhilethehostandanyotherdevicesinthesystemremainoperational.  
When the CYW43340 is not needed in the system, the RF and core supplies are shut down while the I/O remains powered. This  
allows the CYW43340 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 CYW43340, 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 CYW43340 to be fully integrated in an embedded device to take  
full advantage of the lowest power-saving modes.  
Two CYW43340 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  
CYW43340 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.

CYW43340  
5.4.4 Wideband Speech  
The CYW43340 provides support for wideband speech (WBS) using on-chip Smart Audio technology. The CYW43340 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.  
5.4.5 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 CYW43340 uses a proprietary waveform extension algorithm  
to provide dramatic improvement in the audio quality. Figure 8 and Figure 9 show audio waveforms with and without Packet Loss  
Concealment. Cypress PLC/BEC algorithms also support wideband speech.

5.4.6 Audio Rate-Matching Algorithms  
The CYW43340 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 audio data rates.  
5.4.7 Codec Encoding  
The CYW43340 can support SBC and mSBC encoding and decoding for wideband speech.  
5.4.8 Multiple Simultaneous A2DP Audio Stream  
The CYW43340 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.  
5.4.9 Burst Buffer Operation  
The CYW43340 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.

5.5 Adaptive Frequency Hopping  
The CYW43340 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.  
5.6 Advanced Bluetooth/WLAN Coexistence  
The CYW43340 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 CYW43340 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 CYW43340 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 CYW43340 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.  
5.7 Fast Connection (Interlaced Page and Inquiry Scans)  
The CYW43340 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 652 KB of ROM memory for program storage and boot ROM, 195 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 CYW43340 through the UART transports. The mechanism for downloading via UART is  
identical to the proven interface of the CYW4329 and CYW4330 devices.  
6.1 RAM, ROM, and Patch Memory  
The CYW43340 Bluetooth core has 195 KB of internal RAM which is mapped between general purpose scratch pad memory and  
patch memory and 652 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 CYW43340 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 PCM Interface  
The CYW43340 supports two independent PCM interfaces that share the pins with the I2S interfaces. The PCM Interface on the  
CYW43340 can connect to linear PCM Codec devices in master or slave mode. In master mode, the CYW43340 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 CYW43340. The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI  
commands.  
7.1.1 Slot Mapping  
The CYW43340 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.  
7.1.2 Frame Synchronization  
The CYW43340 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.  
7.1.3 Data Formatting  
The CYW43340 may be configured to generate and accept several different data formats. For conventional narrowband speech mode,  
the CYW43340 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.  
7.1.4 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 CYW43340 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.  
7.1.5 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.

CYW43340  
7.2 UART Interface  
The CYW43340 uses a UART for Bluetooth. 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.  
The 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 DMA or the CPU. The UART supports the Bluetooth 4.0 UART HCI specification: 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 CYW43340 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 CYW43340 UARTs  
operate correctly with the host UART as long as the combined baud rate error of the two devices is within ±2% (see Table 12).

7.3 I S Interface  
The CYW43340 supports an independent I2S digital audio port for high-fidelity Bluetooth audio. The I2S interface supports both master  
and slave modes. The I2S signals are:  
I2S clock: I2S SCK  
I2S Word Select: I2S WS  
I2S Data Out: I2S SDO  
I2S Data In: I2S SDI  
I2S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S SDO 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, per the  
I2S specification. The MSB of each data word is transmitted one bit clock cycle after the I2S WS transition, synchronous with the falling  
edge of bit clock. Left-channel data is transmitted when I2S WS is low, and right-channel data is transmitted when I2S WS is high.  
Data bits sent by the CYW43340 are synchronized with the falling edge of I2S_SCK and should be sampled by the receiver on the  
rising edge of I2S_SSCK.  
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.

Note:  
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.  
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.  
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.  
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.  
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.  
The data setup and hold time must not be less than the specified receiver setup and hold time.  
The time periods specified in Figure 17 and Figure 18 on page 33 are defined by the transmitter speed. The receiver specifications  
must match transmitter performance.

8. WLAN Global Functions  
8.1 WLAN CPU and Memory Subsystem  
The CYW43340 includes an integrated ARM Cortex-M3™ processor with internal RAM and ROM. The ARM Cortex-M3 processor is  
a low-power processor that features low gate count, low interrupt latency, and low-cost debug. It is intended for deeply embedded  
applications that require fast interrupt response features. The processor implements the ARM architecture v7-M with support for  
Thumb®-2 instruction set. ARM Cortex-M3 delivers 30% more performance gain over ARM7TDMI®.  
At 0.19 µW/MHz, the Cortex-M3 is the most power efficient general purpose microprocessor available, outperforming 8- and 16-bit  
devices on MIPS/µW. It supports integrated sleep modes.  
ARM Cortex-M3 uses multiple technologies to reduce cost through improved memory utilization, reduced pin overhead, and reduced  
silicon area. ARM Cortex-M3 supports independent buses for code and data access (ICode/DCode and system buses). ARM Cortex-  
M3 supports extensive debug features including real time trace of program execution.  
On-chip memory for the CPU includes 512 KB SRAM and 640 KB ROM.  
8.2 One-Time Programmable Memory  
Various hardware configuration parameters may be stored in an internal 3072-bit 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.  
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.  
8.3 GPIO Interface  
On the WLBGA package, there are 8 GPIO pins available on the WLAN section of the CYW43340 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.  
8.4 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, WiMAX, LTE, or UWB, to manage wireless medium sharing for optimum performance. The coexistence signals in Figure 19  
and Table 15 can be enabled by software on the indicated GPIO pins.

8.5 UART Interface  
One UART interface can be enabled by software as an alternate function on pins WL_GPIO4 and WL_GPIO_5. Provided primarily  
for debugging during development, this UART enables the CYW43340 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.  
8.6 JTAG Interface  
The CYW43340 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.

9.2 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 23 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

10.1.1 MAC Description  
The CYW43340 WLAN MAC is designed to support high-throughput operation with low-power consumption. It does so without  
compromising 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  
synchronization. The architecture diagram of the MAC is shown in Figure 24 on page 40.  
The following sections provide an overview of the important modules in the MAC.

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.  
Document Number: 002-14943 Rev. *L  
Page 40 of 96  
PRELIMINARY  
CYW43340  
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 DMA engine 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. WLAN Radio Subsystem  
The CYW43340 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.  
11.1 Receiver Path  
The CYW43340 has a wide dynamic range, direct conversion receiver. It 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. Control signals are available that can support the use of  
optional external low noise amplifiers (LNA), which can increase the receive sensitivity by several dB.  
11.2 Transmit Path  
Baseband data is modulated and upconverted to the 2.4 GHz ISM or 5-GHz U-NII bands, respectively. The CYW43340 includes an  
on-chip regulator which regulates VBAT down to 3.3V for the CYW43340 on-chip linear Power Amplifiers. Closed-loop output power  
control is provided by means of internal a-band and g-band power detectors.  
11.3 Calibration  
The CYW43340 features dynamic and automatic on-chip calibration to continually compensate for temperature and process variations  
across components. This enables the CYW43340 to be used in high-volume applications, because calibration routines are not  
required during manufacturing testing. 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 test time and cost during large volume  
production.

12.2.1 WLAN GPIO Signals and Strapping Options  
The pins listed in Table 18 on page 53 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 kresistor or less.  
Note: Refer to the reference board schematics for more information.

1. Keeper column: N=pad has no keeper. Y=pad has a keeper. Keeper is always active except in Power-down state.  
2. 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 (e.g., SDIO_CLK).  
3. In the Power-down state (xx_REG_ON=0): High-Z; NoPull => the pad is disabled because power is not supplied.  
4. Depending on whether the PCM interface is enabled and the configuration of PCM is in master or slave mode, it can be either output or input.

5. Depending on whether the I S interface is enabled and the configuration of I S is in master or slave mode, it can be either output or input.  
6. GPIO_6 is input-only during the Low-Power and Deep-Sleep modes.  
7. GPIO_0 through GPIO_5 and GPIO_12 can be configured to operate as inputs or outputs in Deep-Sleep mode before entering the mode.  
8. The GPIO pull states for the Active and Low-Power states are hardware defaults. They can all be subsequently programmed as pull-ups or pull-downs.

15. WLAN RF Specifications  
15.1 Introduction  
The CYW43340 includes an integrated dual-band direct conversion radio that supports either the 2.4 GHz band or the 5 GHz band.  
The CYW43340 does not provide simultaneous 2.4 GHz and 5 GHz operation. This section describes the RF characteristics of the  
2.4 GHz and 5 GHz portions of the radio.  
Values in this data sheet are design goals and are subject to change based on the results of device characterization.  
Unless otherwise stated, limit values apply for the conditions specified inTable 22: “Environmental Ratings,” on page 57 and  
Table 24: “Recommended Operating Conditions and DC Characteristics,” on page 58. Typical values apply for the following condi-  
tions:  
VBAT = 3.6V

CYW43340  
19. Power-Up Sequence and Timing  
19.1 Sequencing of Reset and Regulator Control Signals  
The CYW43340 has three 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 33, Figure 34 on page 88, and Figure 35 and Figure 36 on page 89). The  
timing values indicated are minimum required values; longer delays are also acceptable.  
The WL_REG_ON and BT_REG_ON signals are ORed in the CYW43340. The diagrams show both signals going high at the same  
time (as would be the case if both REG signals were controlled by a single host GPIO). If two independent host GPIOs are used  
(one for WL_REG_ON and one for BT_REG_ON), then only one of the two signals needs to be high to enable the CYW43340  
regulators.  
The CYW43340 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 (see Table 24: “Recommended Operating Conditions and DC Characteristics,”  
on page 58). Wait at least 150 ms after VDDC and VDDIO are available before initiating SDIO accesses.  
VBAT should not rise faster than 40 µs. 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.  
19.1.1 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 CYW43340 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 CYW43340 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 msec 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.

continuous dissipation.  
20.2 Junction Temperature Estimation and PSI Versus THETA  
JT  
JC  
Package thermal characterization parameter PSI–JT (JT) yields a better estimation of actual junction temperature (TJ) versus using  
the junction-to-case thermal resistance parameter Theta–JC (JC). The reason for this is that JC assumes that all the power is  
dissipated through the top surface of the package case. In actual applications, some of the power is dissipated through the bottom  
and sides of the package. JT takes into account 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)
