ATWINC3400 Single Chip IEEE 802.11 b/g/n Network Controller with Integrated Bluetooth 4.0 PRELIMINARY DATASHEET Description The Atmel ATWINC3400 is a single chip IEEE 802.11 b/g/n RF/Baseband/MAC network controller and Bluetooth Low Energy (BLE) 4.0 optimized for low-power mobile applications. The ATWINC3400 supports single stream 1x1 802.11n mode providing up to 72Mbps PHY rate. The ATWINC3400 features fully integrated Power Amplifier, LNA, Switch, and Power Management. ATWINC3400 also features an on-chip microcontroller and integrated Flash memory for system software. Implemented in 65nm CMOS technology, the ATWINC3400 offers very low power consumption while simultaneously providing high performance and minimal bill of materials. The ATWINC3400 utilizes highly optimized 802.11-BLE coexistence protocols. The ATWINC3400 provides multiple peripheral interfaces including UART, SPI, 2 I C, and SDIO. The only external clock sources needed for the ATWINC3400 is a high-speed crystal or oscillator with a wide range of reference clock frequencies supported (14-40MHz) and a 32.768kHz clock for sleep operation. The ATWINC3400 is available in QFN packaging.
