CYW4343W

Single-Chip 802.11 b/g/n MAC/Baseband/Radio

with Bluetooth 4.1

The Cypress CYW4343W is a highly integrated single-chip solution and offers the lowest RBOM in the industry for wearables, Internet

of Things (IoT) gateways, home automation, 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 and Bluetooth 4.1 support. 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 SDIO v2.0 mode, 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 host interface.Using advanced design

techniques and process technology to reduce active and idle power, the CYW4343W 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 CYW4343W 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.

■ OneDriver™ software architecture for easy migration from

existing embedded WLAN and Bluetooth devices as well as to

future devices.

Features

IEEE 802.11x Key Features

Bluetooth 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 Cypress TurboQAM® data rates (256-

QAM) and 20 MHz channel bandwidth.

■ Bluetooth Class 1 or Class 2 transmitter operation.

■ Integrated iTR switch supports a single 2.4 GHz antenna

shared between WLAN and Bluetooth.

■ Supports extended Synchronous Connections (eSCO), for

enhanced voice quality by allowing for retransmission of

dropped packets.

■ Supports explicit IEEE 802.11n transmit beamforming

■ Tx and Rx Low-density Parity Check (LDPC) support for

improved range and power efficiency.

■ Adaptive Frequency Hopping (AFH) for reducing radio

frequency interference.

■ Supports standard SDIO v2.0 host interface.

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

high-speed UART interface and PCM for audio data.

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

■ IntegratedARM 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.

■ Supports multiple simultaneous Advanced Audio Distribution

Profiles (A2DP) for stereo sound.

■ Automatic frequency detection for standard crystal and TCXO

values.
