ATWILC1000B-MU-T

ATWILC1000A is a single chip IEEE 802.11 b/g/n Radio/Baseband/MAC link controller optimized for low-power mobile applications. ATWILC1000A supports single stream 1x1 802.11n mode providing up to 72Mbps PHY rate. The ATWILC1000A features fully integrated Power Amplifier, LNA, Switch, and Power Management. Implemented in 65nm CMOS technology, the ATWILC1000A offers very low power consumption while simultaneously providing high performance and minimal bill of materials. The ATWILC1000A supports two and three Bluetooth coexistence protocols. The ATWILC1000A provides multiple peripheral interfaces including UART, SPI, I²C, and SDIO. The only external clock source needed for the ATWILC1000A is a high-speed crystal or oscillator with a wide range of reference clock frequencies supported (12-40MHz). The ATWILC1000A is available in both QFN and Wafer Level Chip Scale Package (WLCSP) packaging.
