The Cypress CYW43340 single–chip quad–radio device provides the highest level of integration for a mobile or handheld wireless system, with integrated dual band (2.4 GHz / 5 GHz) IEEE 802.11 a/b/g and single–stream IEEE 802.11n MAC/baseband/radio, Bluetooth 4.0, and FM radio receiver. The CYW43340 includes integrated power amplifiers and LNAs for the 2.4 GHz and 5 GHz WLAN bands, and an integrated 2.4 GHz T/R switch. This greatly reduces the external part count, PCB footprint, and cost of the solution. Using advanced design techniques and process technology to reduce active and idle power, the CYW43340 is designed to address the needs of mobile devices that require minimal power consumption and compact size. It includes a power management unit which simplifies the system power topology and allows for operation directly from a mobile platform battery while maximizing battery life. The CYW43340 implements the highly sophisticated Enhanced Collaborative Coexistence algorithms and hardware mechanisms, allowing for an extremely collaborative Bluetooth coexistence scheme along with coexistence support for external radios (such as cellular and LTE, GPS, WiMAX, and Ultra–Wideband) and a single shared 2.4 GHz antenna for Bluetooth and WLAN. As a result, enhanced overall quality for simultaneous voice, video, and data transmission on a handheld system is achieved. For the WLAN section, two host interface options are included: an SDIO v2.0 interface (including gSPI) and a High-Speed Inter-Chip (HSIC) interface (a USB 2.0 derivative for short-distance on-board connections). An independent, high-speed UART is provided for the Bluetooth host interface
