The Cypress CYW4343W is a highly integrated single-chip solution and offers the lowest RBOM in the industry for wearables, Internetof 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 outputpower 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 modeat 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 mobiledevices that require minimal power consumption and compact size. It includes a power management unit that simplifies the systempower 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.
