Atmel adds integrated MCU/Wi-Fi module for edge node IoT applications
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.
The device features;
- Turnkey system with integrated software that includes TLS 1.0 and a TCP/IP stack WPA2 Personal and Enterprise security;
- FCC-certified 2.4GHz IEEE 802.11 b/g/n Wi-Fi WINC1500;
- Atmel | SMART ARM Cortex M0+-based SAM D21; 256KB Flash; 32KB SRAM;
- Serial Peripheral Interface (SPI);
- Over-the-air updates;
- ATECC108A CryptoAuthentication engine with ultra-secure hardware-based key storage for secure connectivity.
To accelerate design development, Atmel will have a SAM W25 integrated module on an Xplained starter kit platform which will be available in December 2014.
Atmel and IAR Systems have extended their relationship to include over 1,400 new example projects in IAR Systems’ development tools to support Atmel’s entire portfolio of MCUs and MPUs. Designers using Atmel AVR and Atmel | SMART MCUs and MPUs can now use IAR Embedded Workbench, the C/C++ compiler and debugger toolchain, with new example projects. With all the information available to a developer at the start of a project, including over 1,400 new examples from the Atmel Software Framework (ASF) for reference designs across a broad range of applications and Atmel’s Xplained Pro family of evaluation boards, this significantly increases developers’ productivity.
ASF is a large library of free source code for Atmel | SMART ARM and AVR devices. ASF minimises much of the low-level configuration and design required for projects to get off the ground, by providing hardware abstraction with consistent APIs, as well as high-value middleware components designed for evaluation, prototyping, design, and production phases.
