Atmel Corp. is collaborating with H&D Wireless to deliver an IEEE802.11b+g Wi-Fi solution for Atmel's 32bit AVR microcontrollers. This collaboration calls for H&D Wireless to provide the SPB104 Wi-Fi extension board which is easily connected to the AVR32 UC3 evaluation kits through the SD card socket. The result is what the companies claims is the most power-efficient Wi-Fi solution, with an overall power consumption 5x lower than any other similar solution on the market.

"Many customers are demanding embedded Wi-Fi solutions in their 32bit MCU applications," said Haakon Skar, product marketing director for AVR32 at Atmel Corp. "To address these needs, Atmel has partnered with H&D Wireless to enable Wi-Fi capability in Atmel's 32bit AVR MCUs. To enable Wi-Fi capabilities of the AVR32 UC3 MCU, 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 Wi-Fi drivers and the full TCP/IP stacks. "

Atmel's picoPower technology meets the toughest requirements in modern MCUs. By combining ten years of low-power research and development into picoPower technology for AVR MCUs, AVR32 MCUs can achieve the industry's lowest power consumption with 0.48mW/MHz in active mode, 1.5?A with RTC running and below 100nA in shutdown mode.

"As a wireless solutions leader, we are thrilled to provide a Wi-Fi solution to a leading MCU provider," said P�r Bergsten, CEO of H&D Wireless. "We have developed a best-in-class Wi-Fi solution with a focus on low power consumption and a small form factor. The solution we are announcing will enable a faster time-to-market for Atmel's customers."

H&D Wireless' modules offer Wi-Fi capability for the 802.11b+g spectrums with a throughput of 1-54Mbit/s. The device offers a 150?W sleep power consumption, 2.4 years of battery life, 220mW RX power and an interface compatible to SDIO and SPI. In addition, the RF power output is 7-8dB higher than the average on the market at +17.5dBm.
