New ARM-Powered Chip Aims for Battery Life Measured in Decades

The number of things getting plugged into the "Internet of Things" has already reached the point of satire. But there's a new, extremely low power technology that's being prepared for market that could put computing power and network access into a whole new class of sensors, wearables, and practically disposable devices. That's because it can run off a battery charge for over over 10 years.

Atmel, the San Jose-based microcontroller maker, today released samples of a new type of ultra-low power, ARM based microcontroller that could radically extend the battery life of small low-power intelligent devices. The new SAM L21 32-bit ARM family of microcontroller (MCUs) consume less than 35 microamps of power per megahertz of processing speed while active, and less than 200 nanoamps of power overall when in deep sleep modeâwith varying states in between.
