The Atmel ATWILC3000 is a single chip IEEE 802.11 b/g/n RF/Baseband/MAC link controller which supports Bluetooth 4.0. The module features fully integrated Power Amplifier, LNA, Switch and Power Management circuitry. It has been designed for very low power consumption and for integration in to mobile devices and thus requires a minimal bill of materials. The module supports single stream 1x1 802.11n mode and provide up to 72 Mbps throughput. It utilizes highly optimized 802.11-Bluetooth coexistence protocols and provides multiple peripheral interfaces including UART, SPI, I2C, and SDIO. The only external clock sources needed for the ATWILC3000 is a high-speed crystal or oscillator with a wide range of reference clock frequencies supported (14-40 MHz) and a 32.768 kHz clock for sleep operation. The ATWILC3000 is available in both QFN and Wafer Level Chip Scale Package (WLCSP) packaging.
