Single-Chip IEEE 802.11 b/g/n MAC/  
Baseband/Radio  
The Cypress CYW43364 is a highly integrated single-chip solution and offers the lowest RBOM in the industry for Internet of Things  
(IoT) and a wide range of other portable devices. The chip includes a 2.4 GHz WLAN IEEE 802.11 b/g/n MAC/baseband/radio. In  
addition, it integrates a power amplifier (PA) that meets the output power requirements of most handheld systems, a low-noise amplifier  
(LNA) for best-in-class receiver sensitivity, and an internal transmit/receive (iTR) RF switch, further reducing the overall solution cost  
and printed circuit board area.  
The WLAN host interface supports gSPI and SDIO v2.0 modes, providing a raw data transfer rate up to 200 Mbps when operating in  
4-bit mode at a 50 MHz bus frequency.  
Using advanced design techniques and process technology to reduce active and idle power, the CYW43364 is designed to address  
the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power management unit  
that simplifies the system power topology while maximizing battery life.  
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 CYW43364. All regulators  
are programmable via the PMU to simplify the power supply.  
A single VBAT (3.0V to 4.8V DC maximum) and VDDIO supply (1.8V to 3.3V) can be used, with all additional voltages being provided  
by the regulators in the CYW43364.  
The WL_REG_ON control signal is used to power up the regulators and take the respective circuit blocks 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 WL_REG_ON  
is deasserted. The CLDO and LNLDO can be turned on and off based on the dynamic demands of the digital baseband.  
The CYW43364 allows for an extremely low power-consumption mode by completely shutting down the CBUCK, CLDO, and LNLDO  
regulators. When in this state, LPLDO1 provides the CYW43364 with all required voltage, further reducing leakage currents.  
Notes:  
VBAT should be connected to the LDO_VDDBAT5V and SR_VDDBAT5V pins of the device.  
VDDIO should be connected to the SYS_VDDIO and WCC_VDDIO pins of the device.  
2.2 CYW43364 PMU Features  
The PMU supports the following:  
VBAT to 1.35Vout (170 mA nominal, 370 mA maximum) Core-Buck (CBUCK) switching regulator  
VBAT to 3.3Vout (250 mA nominal, 450 mA maximum 800 mA peak maximum) LDO3P3  
1.35V to 1.2Vout (100 mA nominal, 150 mA maximum) LNLDO  
1.35V to 1.2Vout (80 mA nominal, 200 mA maximum) CLDO with bypass mode for deep sleep  
Additional internal LDOs (not externally accessible)  
PMU internal timer auto-calibration by the crystal clock for precise wake-up timing from extremely low power-consumption mode.

CYW43364  
2.3 WLAN Power Management  
The CYW43364 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 CYW43364 integrated RAM is a high volatile memory with dynamic clock control. The dominant  
supply current consumed by the RAM is leakage current only. Additionally, the CYW43364 includes an advanced WLAN power  
management unit (PMU) sequencer. The PMU sequencer provides significant power savings by putting the CYW43364 into various  
power management states appropriate to the operating environment and the 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 the 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 CYW43364 WLAN power states are described as follows:  
Active mode: All WLAN blocks in the CYW43364 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 CYW43364 remains  
powered up in an IDLE state. All main clocks (PLL, crystal oscillator) 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 analog and digital domains, and most of the regulators are powered off. Logic states  
in the digital core are saved and preserved to retention memory in the always-on domain before the digital core is powered off. To  
avoid lengthy hardware reinitialization, the logic states in the digital core are restored to their pre-deep-sleep settings when a wake-  
up event is triggered by an external interrupt, a host resume through the SDIO bus, or by the PMU timers.  
Power-down mode: The CYW43364 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 used to minimize system power consumption. It enables and disables various system resources based on a  
computation of required resources and a table that describes the relationship between resources and the time required to enable and  
disable them.  
Resource requests can derive 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 the following four states:  
enabled  
disabled  
transition_on  
transition_off  
The timer value is 0 when the resource is enabled or disabled and nonzero during state transition. 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 transition immediately from disabled to enabled. Similarly, a time_off value of 0 indicates that  
the resource can transition 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 nonzero. 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.

CYW43364  
2.5 Power-Off Shutdown  
The CYW43364 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 CYW43364 is not needed in the system, VDDIO_RF and VDDC are shut down while  
VDDIO remains powered. This allows the CYW43364 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 shutdown state, provided VDDIO remains applied to the CYW43364, 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 CYW43364 to be fully integrated in an embedded device and  
to take full advantage of the lowest power-savings modes.  
When the CYW43364 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 CYW43364 has two signals (see Table 2) that enable or disable the 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 14.:  
“Power-Up Sequence and Timing,” on page 62.  
Table 2. Power-Up/Power-Down/Reset Control Signals  
Signal  
Description  
This signal is used by the PMU to power-up the WLAN section. 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. 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. No software settings are required to  
differentiate between the two. In addition, a low-power oscillator (LPO) is provided for lower power mode timing.  
3.1 Crystal Interface and Clock Generation  
The CYW43364 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 5. Consult the reference schematics for the latest configuration.

WLRF_XTAL_XON  
R
12 – 27 pF  
Note: Resistor value determined by crystal  
drive level. See reference schematics for  
details.  
The CYW43364 uses a fractional-N synthesizer to generate the radio frequencies, clocks, and data/packet timing so that it can operate  
using numerous frequency references. The frequency reference can be an external source such as a TCXO or a crystal interfaced  
directly to the CYW43364.  
The default frequency reference setting is a 37.4 MHz crystal or TCXO. The signal requirements and characteristics for the crystal  
interface are shown in Table 3 on page 12.  
Note: Although the fractional-N synthesizer can support many 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 on page 12.  
If the TCXO is dedicated to driving the CYW43364, it should be connected to the WLRF_XTAL_XOP pin through an external capacitor  
with value ranges from 200 pF to 1000 pF as shown in Figure 6.

3.3 External 32.768 kHz Low-Power Oscillator  
The CYW43364 uses a secondary low-frequency sleep 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 that meets the requirements listed in Table  
4 on page 13.  
Note: The CYW43364 will auto-detect the LPO clock. If it senses a clock on the EXT_SLEEP_CLK pin, it will use that clock. If it  
doesn't sense a clock, it will use its own internal LPO.  
To use the internal LPO: Tie EXT_SLEEP_CLK to ground. Do not leave this pin floating.  
To use an external LPO: Connect the external 32.768 kHz clock to EXT_SLEEP_CLK.

4. WLAN System Interfaces  
4.1 SDIO v2.0  
The CYW43364 WLAN section supports SDIO version 2.0. for both 1-bit (25 Mbps) and 4-bit modes (100 Mbps), as well as high speed  
4-bit mode (50 MHz clocks—200 Mbps). It has the ability to map the interrupt signal on a GPIO pin. This out-of-band interrupt signal  
notifies the host when the WLAN device wants to turn on the SDIO interface. The ability to force control of the gated clocks from within  
the WLAN chip is also provided.  
SDIO mode is enabled using the strapping option pins. See Table 11 on page 41 for details.  
Three functions are supported:  
Function 0 standard SDIO function. The maximum block size is 32 bytes.  
Function 1 backplane function to access the internal System-on-a-Chip (SoC) address space. The maximum block size is 64 bytes.  
Function 2 WLAN function for efficient WLAN packet transfer through DMA. The maximum block size is 512 bytes.

Write  
The host puts the first bit of the data onto the bus half a clock-cycle before the first active edge following the CS going low. The following  
bits are clocked out on the falling edge of the gSPI clock. The device samples the data on the active edge.  
Write/Read  
The host reads on the rising edge of the clock requiring data from the device to be made available before the first rising-clock edge  
of the data. The last clock edge of the fixed delay word can be used to represent the first bit of the following data word. This allows  
data to be ready for the first clock edge without relying on asynchronous delays.  
Read  
The read command always follows a separate write to set up the WLAN device for a read. This command differs from the write/read  
command in the following respects: a) chip selects go high between the command/address and the data, and b) the time interval  
between the command/address is not fixed.

Status  
The gSPI interface supports status notification to the host after a read/write transaction. This status notification provides information  
about packet errors, protocol errors, available packets in the RX queue, etc. The status information helps reduce the number of  
interrupts to the host. The status-reporting feature can be switched off using a register bit, without any timing overhead. The gSPI bus  
timing for read/write transactions with and without status notification are as shown in Figure 13 below and Figure 14 on page 20. See

4.2.2 gSPI Host-Device Handshake  
To initiate communication through the gSPI after power-up, the host needs to bring up the WLAN chip by writing to the wake-up WLAN  
register bit. Writing a 1 to this bit will start up the necessary crystals and PLLs so that the CYW43364 is ready for data transfer. The  
device can signal an interrupt to the host indicating that the device is awake and ready. This procedure also needs to be followed for  
waking up the device in sleep mode. The device can interrupt the host using the WLAN IRQ line whenever it has any information to  
pass to the host. On getting an interrupt, the host needs to read the interrupt and/or status register to determine the cause of the  
interrupt and then take necessary actions.

CYW43364  
4.2.3 Boot-Up Sequence  
After power-up, the gSPI host needs to wait 50 ms for the device to be out of reset. For this, the host needs to poll with a read command  
to F0 address 0x14. Address 0x14 contains a predefined bit pattern. As soon as the host gets a response back with the correct register  
content, it implies that the device has powered up and is out of reset. After that, the host needs to set the wake-up WLAN bit (F0 reg  
0x00 bit 7). Wake-up WLAN turns the PLL on; however, the PLL doesn't lock until the host programs the PLL registers to set the crystal  
frequency.  
For the first time after power-up, the host needs to wait for the availability of the low-power clock inside the device. Once it is available,  
the host needs to write to a PMU register to set the crystal frequency. This will turn on the PLL. After the PLL is locked, the chipActive  
interrupt is issued to the host. This indicates device awake/ready status. See Table 7 for information on gSPI registers.

Document Number: 002-14781 Rev. *C  
Page 24 of 68  
PRELIMINARY  
CYW43364  
PSM  
The programmable state machine (PSM) is a microcoded engine that 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 scratch-pad  
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 collocated 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, an instruction literal,  
or a program stack. For ALU operations, the operands are obtained from shared memory, scratch-pad memory, IHRs, or instruction  
literals, and the results are written into the shared memory, scratch-pad memory, 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 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, as  
well as the MIC computation and verification. The accelerators implement the following cipher algorithms: legacy WEP, WPA TKIP,  
and WPA2 AES-CCMP.  
Based on the frame type and association information, the PSM determines 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 transmit engine (TXE) to encrypt and  
compute the MIC on transmit frames and the receive engine (RXE) to decrypt and verify the MIC on receive frames. WAPI is also  
supported.  
TXE  
The transmit engine (TXE) constitutes the transmit data path of the MAC. It coordinates the DMA engines to store the transmit frames  
in the TXFIFO. It interfaces with WEP module to encrypt frames and transfers the frames across the MAC-PHY interface at the  
appropriate time determined by the channel access mechanisms.  
The data received from the DMA engines are stored in transmit FIFOs. The MAC supports multiple logical queues to support traffic  
streams that have different QoS priority requirements. The PSM uses the channel access information from the IFS module to schedule  
a queue from which the next frame is transmitted. Once the frame is scheduled, the TXE hardware transmits the frame based on a  
precise timing trigger received from the IFS module.  
The TXE module also contains the hardware that allows the rapid assembly of MPDUs into anA-MPDU for transmission. The hardware  
module aggregates the encrypted MPDUs by adding appropriate headers and pad delimiters as needed.  
RXE  
The receive engine (RXE) constitutes the receive data path of the MAC. It interfaces with the DMAengine to drain the received frames  
from the RX FIFO. It transfers bytes across the MAC-PHY interface and interfaces with the WEP module to decrypt frames. The  
decrypted data is stored in the RX FIFO.  
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  
back-off 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 back-off engines (for each access category) monitor channel activity, in each slot duration, to determine whether to continue or  
pause the back-off counters. When the back-off counters reach 0, the TXE gets notified so that it may commence frame transmission.  
In the event of multiple back-off counters decrementing to 0 at the same time, the hardware resolves the conflict based on policies  
provided by the PSM.

CYW43364  
The IFS module also incorporates hardware that allows the MAC to enter a low-power state when operating under the IEEE power-  
saving 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.  
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 a programming  
interface, which can be controlled either by the host or the PSM to configure and control the PHY.  
5.2 PHY Description

The PHY is capable of fully calibrating the RF front-end to extract the highest performance. On power-up, the PHY performs a full  
calibration suite to correct for IQ mismatch and local oscillator leakage. The PHY also performs periodic calibration to compensate  
for any temperature related drift, thus maintaining high-performance over time. A closed-loop transmit control algorithm maintains the  
output power at its required level and can control TX power on a per-packet basis.

6. WLAN Radio Subsystem  
The CYW43364 includes an integrated WLAN RF transceiver that has been optimized for use in 2.4 GHz Wireless LAN systems. It  
is designed to provide low power, low cost, and robust communications for applications operating in the globally available 2.4 GHz  
unlicensed ISM band. The transmit and receive sections include all on-chip filtering, mixing, and gain control functions. Improvements  
to the radio design include shared TX/RX baseband filters and high immunity to supply noise.

6.1 Receive Path  
The CYW43364 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.  
6.2 Transmit Path  
Baseband data is modulated and upconverted to the 2.4 GHz ISM band. A linear on-chip power amplifier is included, which is capable  
of delivering high output powers while meeting IEEE 802.11b/g/n specifications without the need for an external PA. This PAis supplied  
by an internal LDO that is directly supplied by VBAT, thereby eliminating the need for a separate PALDO. Closed-loop output power  
control is integrated.  
6.3 Calibration  
The CYW43364 features dynamic on-chip calibration, eliminating process variation across components. This enables the CYW43364  
to be used in high-volume applications because calibration routines are not required during manufacturing testing. These calibration  
routines are performed periodically during normal radio operation. Automatic calibration examples include baseband filter calibration  
for optimum transmit and receive performance and LOFT calibration for leakage reduction. In addition, I/Q calibration, R calibration,  
and VCO calibration are performed on-chip.

7. CPU and Global Functions  
7.1 WLAN CPU and Memory Subsystem  
The CYW43364 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 debugging. It is intended for deeply embedded  
applications that require fast interrupt response features. The processor implements the ARM architecture v7-M with support for the  
Thumb-2 instruction set. ARM Cortex-M3 provides a 30% 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 tracing of program execution.  
On-chip memory for the CPU includes 512 KB SRAM and 640 KB ROM.  
7.2 One-Time Programmable Memory  
Various hardware configuration parameters may be stored in an internal 4096-bit One-Time Programmable (OTP) memory, which is  
read by system software after a 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 memory programming, all values should be verified using the appropriate editable nvram.txt file, which is provided with  
the reference board design package. Documentation on the OTP development process is available on the Cypress customer support  
portal (http://community.cypress.com/).  
7.3 GPIO Interface  
Five general-purpose I/O (GPIO) pins are available on the CYW43364 that can be used to connect to various external devices.  
GPIOs are tristated by default. Subsequently, they can be programmed to be either input or output pins via the GPIO control register.  
They can also be programmed to have internal pull-up or pull-down resistors.  
GPIO_0 is normally used as a WL_HOST_WAKE signal.  
The CYW43364 supports 2-wire, 3-wire, and 4-wire coexistence configurations using GPIO_1 through GPIO_4. The signal functions  
of GPIO_1 through GPIO_4 are programmable to support the three coexistence configurations.

7.4 External Coexistence Interface  
The CYW43364 supports 2-wire, 3-wire, and 4-wire coexistence interfaces to enable signaling between the device and an external  
colocated wireless device in order to manage wireless medium sharing for optimal performance. The external colocated device can  
be any of the following ICs: GPS, WiMAX, LTE, or UWB. An LTE IC is used in this section for illustration.

7.5 JTAG Interface  
The CYW43364 supports the IEEE 1149.1 JTAG boundary scan standard over SDIO 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 characterization 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.  
7.6 UART Interface  
One UART interface can be enabled by software as an alternate function on the JTAG pins. UART_RX is available on the JTAG_TDI  
pin, and UART_TX is available on the JTAG_TDO pin.  
The UART is primarily for debugging during development. By adding an external RS-232 transceiver, this UART enables the  
CYW43364 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 it provides a FIFO size of 64 × 8 in each direction.

8.5 WLAN GPIO Signals and Strapping Options  
The pins listed in Table 11 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 ground using  
a 10 kresistor or less.  
Note: Refer to the reference board schematics for more information.

14. Power-Up Sequence and Timing  
14.1 Sequencing of Reset and Regulator Control Signals  
The CYW43364 WL_REG_ON signal allows the host to control power consumption by enabling or disabling the 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 27 and Figure 28). The timing values indicated are minimum required values; longer delays  
are also acceptable.  
Note:  
The CYW43364 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 17 on page 45). Wait at least 150 ms after VDDC and VDDIO are  
available before initiating SDIO accesses.  
VBAT and VDDIO 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.

dissipation.  
b. Absolute junction temperature limits maintained through active thermal monitoring and dynamic TX duty cycle limiting.  
15.1.1 Junction Temperature Estimation and PSI Versus Thetajc  
Package thermal characterization parameter PSI-JT () yields a better estimation of actual junction temperature (T ) versus using  
JT  
J
the junction-to-case thermal resistance parameter Theta-J (JC). The reason for this is JC assumes that all the power is dissipated  
C
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. takes into account power dissipated through the top, bottom, and sides of the package. The equation for calculating  
JT  
the device junction temperature is as follows:  
TJ = TT + P JT  
Where:  
T = junction temperature at steady-state condition, °C  
J
T = package case top center temperature at steady-state condition, °C  
T
P = device power dissipation, Watts
