Ultra-low power IoT platform targets secure Cloud access

May 06, 2015 // By Paul Buckley
MXCHIP, a Chinese IoT start-up, is jointly developing an ultra-low power Internet of Things (IoT) platform with Atmel that offers secure Wi-Fi access to the cloud, enabling designers to quickly bring their IoT devices to market.

The joint platform will combine Atmel's ultra-low power Atmel | SMART SAM G ARM Cortex-M4-based MCUs and its SmartConnect WILC1000 Wi-Fi solution with MXCHIP's MiCO IoT operating system (OS), servicing a full range of smart device developers for IoT applications.

With the rapid growth of the IoT market, smart, connected devices will require secure access to the cloud on what will likely be billions of battery-operated devices. The new platform combines Atmel's proven ultra-low power SAM G series of MCUs, designed for wearables and sensor hub management, and Atmel's secure ultra-low power SmartConnect WILC1000 Wi-Fi solution with MXCHIP's leading MiCO IoT OS for next-generation IoT applications. The integrated platform gives IoT designers the confidence that their battery-operated devices will have longer battery life and their data will be securely transferred to the cloud.

Atmel's WILC1000 is an IEEE 802.11b/g/n IoT link controller using the company's ultra-low power Wi-Fi transceiver with a fully integrated power amplifier. The solution claims to deliver the industry's best communication range of up to +20.5 dBm output, ideal for connected home devices. Integrated in packages as small as a 3.2 mm x 3.2 mm WLCSP, the Atmel WILC1000 link controller leverages in this platform Atmel's SAM G MCU, an ideal solution for low-power IoT applications and optimized for lower power consumption, incorporating large SRAM, high performance and operating efficiency with floating-point unit in an industry-leading 2.84 mm x 2.84 mm package. When combined with secure Wi-Fi technology, the joint IoT platform connects directly to each other or to a local area network (LAN), enabling remote system monitoring or control. For increased security, the platform comes with an optional Atmel ATECC508A - the industry's first crypto device to integrate ECDH key agreement, making it easy to add confidentiality to digital systems including IoT nodes used in home automation, industrial networking, accessory and consumable authentication, medical, mobile and other applications.
