CYW43438

Single-Chip IEEE 802.11ac b/g/n MAC/Baseband/

Radio with Integrated Bluetooth 4.1 and FM Receiver

The Cypress CYW43438 is a highly integrated single-chip solution and offers the lowest RBOM in the industry for smartphones,

tablets, 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,

Bluetooth 4.1 support, and an FM receiver. 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. An independent, high-speed UART is provided for the Bluetooth/FM host interface.

Using advanced design techniques and process technology to reduce active and idle power, the CYW43438 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 and allows for operation directly from a rechargeable mobile platform battery while

maximizing battery life.

The CYW43438 implements the world’s most advanced Enhanced Collaborative Coexistence algorithms and hardware

mechanisms, allowing for an extremely collaborative WLAN and Bluetooth coexistence.

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.

Features

IEEE 802.11x Key Features

Bluetooth and FM Key Features

■ Single-band 2.4 GHz IEEE 802.11b/g/n.

■ Complies with Bluetooth Core Specification Version 4.1 with

provisions for supporting future specifications.

■ Support for 2.4 GHz Broadcom TurboQAM^®data rates (256-

■ Bluetooth Class 1 or Class 2 transmitter operation.

QAM) and 20 MHz channel bandwidth.

■ Supports extended Synchronous Connections (eSCO), for

enhanced voice quality by allowing for retransmission of

dropped packets.

■ Integrated iTR switch supports a single 2.4 GHz antenna

shared between WLAN and Bluetooth.

■ Supports explicit IEEE 802.11n transmit beamforming.

■ Adaptive Frequency Hopping (AFH) for reducing radio fre-

■ Interface support — Host Controller Interface (HCI) using a

■ Supports standard SDIO v2.0 and gSPI host interfaces.

■ Supports Space-Time Block Coding (STBC) in the receiver.

high-speed UART interface and PCM for audio data.

■ FM receiver unit supports HCI for communication.

■ Integrated ARM Cortex-M3 processor and on-chip memory

for complete WLAN subsystem functionality, minimizing the

need to wake up the applications processor for standard

WLAN functions. This allows for further minimization of

power consumption, while maintaining the ability to field-

upgrade with future features. On-chip memory includes 512

KB SRAM and 640 KB ROM.

■ Low-power consumption improves battery life of handheld

devices.

■ FM receiver: 65 MHz to 108 MHz FM bands; supports the

European Radio Data Systems (RDS) and the North Ameri-

can Radio Broadcast Data System (RBDS) standards.

■ Supports multiple simultaneous Advanced Audio Distribution

Profiles (A2DP) for stereo sound.

■ OneDriver^™software architecture for easy migration from

existing embedded WLAN and Bluetooth devices as well as

to future devices.

■ Automatic frequency detection for standard crystal and

TCXO values.
