Atmel / Microchip ATWILC3000 Wi-Fi® Modules

Atmel / Microchip ATWILC3000 Wi-Fi® Modules are an IEEE 802.11 b/g/n  RF/Baseband/MAC link controllers and are compliant to BLUETOOTH® 4.0 module optimized for low-power mobile applications. These modules offer single-stream 1x1 IEEE 802.11n mode and provide up to 72Mbps PHY rate. The ATWILC3000 WiFi modules feature very low power consumption and provide high performance. These modules include a chip antenna, a 26MHz crystal, a PMU circuitry, and require a 32.768kHz clock for sleep operation. The ATWILC3000 WiFi modules operate at -40°C to 85°C temperature range and offer 22.43mm x 14.73mm dimensions.
