CYW4343X

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

Baseband/Radio with Bluetooth 4.1,

an FM Receiver, and Wireless Charging

The Cypress CYW4343X is a highly integrated single-chip solution and offers the lowest RBOM in the industry for smartphones

smartphones wearables, 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 out-

put 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 CYW4343X 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 CYW4343X implements the world’s most advanced Enhanced Collaborative Coexistence algorithms and hardware mecha-

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