These make it easy to integrate Wi-Fi capability for a variety of embedded systems in building automation, metering, digital audio and medical applications.

Atmel Corporation and Redpine Signals have announced that 802.11n Wi-Fi can be implemented for all Atmel AVR and ARM-based microcontrollers (MCUs) using Redpine Signals’ Connect-io-n and n-Link modules, designed to make it easy to integrate Wi-Fi capability for a variety of embedded systems in building automation, metering, digital audio and medical applications.

Atmel customers can add 802.11a/b/g/n Wi-Fi connectivity using two solutions from Redpine Signals that are optimized for Atmel MCUs. The fully-certified Redpine Connect-io-n Wi-Fi modules with integrated TCP/IP stack are well-suited for Atmel AVR XMEGA, AVR UC3 MCUs, and SAM3 ARM-based MCUs, while the high-performance n-Link modules 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 45Mbps of data throughput on SDIO interfaces.
