Atmel and Redpine Signals Collaborate to Provide Ultra-Low-Power 802.11n Wi-Fi Capability for AVR and ARM-based Microcontrollers

Community of 100K+ designers for Atmel AVR and ARM-based microcontrollers can now easily implement wireless connectivity with Redpine Signals’ 802.11n solutions for industrial and residential applications

San Jose, CA, September 27, 2011—If you’re not used to thinking of “Wi-Fi” and “low power” in the same sentence, think again.

Atmel Corporation and Redpine Signals today announced that system engineers can easily implement 802.11n Wi-Fi to all Atmel AVR and ARM-based microcontrollers (MCUs) using Redpine Signals’ Connect-io-n and n-Link modules. System engineers for Atmel AVR XMEGA and AVR UC3 MCU families and Atmel SAM3 and SAM9 ARM-based MCU families can now integrate Wi-Fi capability for a variety of embedded systems in building automation, metering, digital audio and medical applications.

Venkat Mattela, Redpine Signals CEO, explained to Low-Power Design that today’s announcement leverages the ultra-low power 802.11n module for the embedded market (Connect-io-n) that Redpine introduced back in 2005, now matched with one of Atmel’s lowest power MCUs.

Atmel customers can add 802.11a/b/g/n Wi-Fi connectivity using two easy-to-use solutions from Redpine Signals, which are optimized for Atmel MCUs. The fully-certified Connect-io-n Wi-Fi modules with integrated TCP/IP stack are ideal for Atmel AVR XMEGA and AVR UC3 MCUs, and Atmel SAM3 ARM-based MCUs, while the low-cost n-Link chipset with host-managed TCP/IP stack are ideal for Atmel SAM9 ARM-based MCUs. Redpine’s Connect-io-n and n-Link solutions connect to Atmel MCUs  through UART, SPI and SDIO interfaces and offer up to 65Mbps of physical bit rate  and up to 45 Mbps of data throughput on SDIO interface. System designers can purchase Wi-Fi kits from Redpine Signals, designed to work with Atmel Xplained boards and evaluation kits (EV). The Wi-Fi kit includes optimized drivers and code examples free of charge and customers can also download Linux drivers to use with the Atmel SAM9 ARM-based MCUs.

“Redpine has pioneered low-power 802.11n Wi-Fi technology for over 10 years and established itself as a preferred provider of Wi-Fi connectivity for emerging industrial, medical, residential and smart energy markets,” said Mattela. “By offering 11n Wi-Fi connectivity for the leading Atmel AVR and ARM-based microcontrollers, including the AVR XMEGA, AVR UC3 and SAM3 and SAM9 ARM-based families, we believe it is a ‘win-win’ for both companies. Our mature, proven module design and manufacturing expertise, combined with our optimal silicon architecture, has enabled us to provide 802.11n single-stream solutions at a lower cost than legacy 802.11b and 802.11b/g solutions.”

 “Wi-Fi connectivity is fast making its way into embedded applications,” said Øyvind Strøm, sr. director of wireless marketing, Atmel Corporation. “Our customers are looking for low-power Wi-Fi connectivity for their embedded applications to complement the emerging 802.11n infrastructure network. This is an ideal time to add Wi-Fi capability to our MCU families, and we are excited to collaborate with Redpine Signals to bring more Wi-Fi connectivity to market.”

Pricing and Availability
To begin evaluation, customers may purchase an Atmel evaluation kit, such as the Xplained kit, and a Wi-Fi kit from Redpine Signals. The Atmel Xplained and EV kits are available from Atmel and its distribution partners with a suggested retail price starting at $29. The Redpine Signals Wi-Fi kits are available from Redpine Signals with a suggested retail price starting at $79.
