Atmel adds integrated MCU/Wi-Fi module for edge node IoT applications

November 17, 2014 // By Graham Prophet
In the Atmel | SMART portfolio of SmartConnect low-power, secure Wi-Fi solutions, this FCC-certified module offers a complete standalone edge node solution delivering that promises design flexibility and security for IoT developers

Positioned as the first fully integrated FCC-certified Wi-Fi module with a standalone MCU and hardware security from a single source, the SmartConnect SAM W25 module includes Atmel's recently announced 2.4 GHz IEEE 802.11b/g/n Wi-Fi WINC1500, along with an Atmel | SMART SAM D21 ARM Cortex M0+-based MCU and Atmel’s ATECC108A optimised CryptoAuthentication engine with ultra-secure hardware-based key storage for secure connectivity.

There is a need, Atmel says flexible, for cost-optimised modules that provide a complete end-point solution from a single vendor. The fully integrated SAM W25 delivers a secure 'plug and play’ solution integrating wireless technologies with the design flexibility required for Internet of Things (IoT) designers.

Devices in edge nodes IoT applications will be powered by an embedded processing unit such as an MCU, and connected through a secure wireless signal. As more embedded developers start designing IoT applications for smart, secure connected devices, the need for solutions that integrate both an MCU, hardware security and pre-certified wireless connectivity solution into one box will become a critical piece of the IoT puzzle so designers won’t need wireless or encryption expertise to create an IoT solution. Atmel’s FCC-, Telec-, IC- and CE-certified SAM W25 is a standalone solution that gives designers a fully integrated platform with a low-power MCU, hardware security and FCC-certified wireless connectivity from a single source. The small packaged module is cost optimised to lower the overall bill of materials for battery-operated applications ranging from remotes to home automation devices and beyond.
