SmartConnect WINC3400
Wireless Network Controller

   The Atmel® SmartConnect ATWINC3400 is a single-chip IEEE 802.11 b/g/n RF/Baseband/MAC network controller and Bluetooth® 4.0 Low Energy (BLE) compliant module optimized for low-power mobile applications. It supports single stream 1x1 802.11n mode, providing up to 72 Mbps throughput. The ATWINC3400 device features a fully integrated power amplifier, LNA, switch and power management, as well as an on-chip microcontroller (MCU) and integrated Flash memory for system software. Implemented in 65nm CMOS technology, it offers very low power consumption while simultaneously providing high performance and a minimal bill of materials.
