This is the lowest power consuming 32bit ARM Processor in the world based on ARM Cortex-M0+ for wearables (can be with basic touch) and for the sensor networks in the Internet of Things, can run up to more than a decade on a battery. The new Ultra low power Atmel | SMART SAM L21 based on the ARM Cortex-M0+ Core uses less than a third of the power consumption of competitive solutions and can run in active mode down to 35uA/MHz and retain 32kB of Flash and run a real time clock at 900nA. In this demo the SAM L21 is powered from the heat of a hand through a Peltier Element, this is enough energy to modulate a music file and transmit it with AM modulation at 1MHz to the nearby radio receiver. This demo shows that the SAM L21 is truly unique in supporting ultra-low power consumption in active mode without having to limit Flash or SRAM size, it is perfect for IoT and other battery powered applications where large embedded memories are needed.
