CYW4343X

Single-Chip IEEE b/g/n MAC/ Baseband/Radio with Bluetooth 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 wearables, tablets, and a wide range of other portable devices. The chip includes a GHz WLAN IEEE b/g/n MAC/baseband/radio, Bluetooth 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 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 mechanisms, allowing for an extremely collaborative WLAN and Bluetooth coexistence.
