Video: Andreas Eieland talks Atmel | SMART SAM L21


Low power just got a whole heck of a lot lower.


During CES 2015, ARMdevices.net had the chance to catch up with Andreas Eieland, Atmel Senior Product Marketing Manager, to discuss the recently-revealed Atmel | SMART SAM L21.

The SAM L21 not only boasts the performance of an ARM Cortex-M0+ core, it also consumes just one-third the power of comparable products in the market today. The Atmel | SMART MCU delivers ultra-low power running down to 35µA/MHz in active mode, consuming less than 900nA with full 32kB RAM retention. With rapid wake-up times, Event System, Sleepwalking and the innovative picoPower peripherals, the SAM L21 family is ideal for handheld and battery-operated devices for a variety of Internet of Things (IoT) applications.

In Eieland’s video below, 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 latest ARM Cortex-M0+ MCU is truly unique in supporting ultra-low power consumption in active mode without having to limit Flash or SRAM size.

(And, let us apologize ahead of time for the Rick Astley tune that’ll surely be stuck in your head. You’ll see what we mean around the 2:30 mark.)
