Ultra-low-power connected platform for wearable products

January 08, 2016 // By Graham Prophet
Atmel’s latest platform for cost-optimised IoT and wearable designs integrates the ultra-low-power Atmel | SMART SAM L21 MCU with a BTLC1000 BLE and software into a small, flexible form factor.

Atmel positions the offering as a complete, ultra-low-power connected platform that features the lowest power ARM Cortex-M0+, the Atmel | SMART SAM L21, and BTLC1000 Bluetooth SMART chipset, for battery-operated applications requiring activity and environment monitoring.

The SAM L21 achieves a ULPBench score of 185, claimed as the highest recorded score for any Cortex-M0+ while running the EEMBC ULPBench, with a power consumption down to 35 µA/MHz in active mode and 200 nA in sleep mode. Atmel’s Bluetooth SMART solution is 25% smaller than the closest competing solution packaged in a 2.2 x 2.1 mm Wafer Level Chipscale Package, enabling designers to build ultra-small industrial designs for next-generation connected IoT and wearable applications.

Atmel’s low-power connected platform is a design-ready unit showcasing the company’s broad portfolio of ultra-low-power smart, secure and connected products, and partner technologies. Embodied in a 30 x 40 mm form factor, the platform integrates the Atmel | SMART ultra-low power MCU, Bluetooth SMART low-energy connectivity, capacitive touch interface, security solution, complete software platform, real-time operating system (RTOS), a BHI160 6-axis SmartHub motion sensor and a BME280 environmental sensor from Bosch Sensortec. The platform can be powered by a simple coin cell with extremely low power consumption, and manufacturers can also build on Atmel’s list of sensor partners.
