Power efficient embedded WiFi solution

Atmel is collaborating with H&D Wireless to deliver an IEEE802.11b+g WiFi solution for Atmel's 32bit AVR microcontrollers. In this collaboration, H&D Wireless will provide the SPB104 WiFi extension board which is easily connected to the AVR32 UC3 evaluation kits through the SD card socket. To enable WiFi capabilities of the AVR32 UC3 microcontroller, a customer only needs an ATEXTWIFI evaluation board, an AVR32 EVK1104 or EVK1105 evaluation kit, and to download a free AVR32 Software Framework 1.5 version which includes all WiFi drivers and the full TCP/IP stacks. The AVR32 MCUs utilise picoPower technology and consume reduced energy in active and standby modes. The AVR32 MCUs consume 0.48mW/MHz in active mode, 1.5uA with RTC running and below 100nA in shutdown mode. H&D Wireless' modules offer WiFi capability for the 802.11b+g spectrums with a throughput of 1 to 54Mbit/s. The device offers a 150uW sleep power consumption, 2.4 years of battery life, 220mW RX power and an interface compatible to SDIO and SPI.
