Low power just got lower with the Atmel | SMART SAM L21

Well, low power just got lower. The Atmel team is excited to announce that it has reached a new low-power standard for its ARM Cortex-M0+ based MCUs with power consumption down to 40 µA/MHz in active mode and 200nA in sleep mode. In addition to ultra-low power, the new platform features full-speed USB host and device, Event System and Sleepwalking,12-bit analog, AES, capacitive touch sensing and much more.

With billions of devices predicted for the Internet of Things (IoT) market by 2020, there is a need for lower power MCUs that will power these applications without adding load to utility grids or requiring frequent battery changes. Atmel’s latest Atmel | SMART platform is designed specifically for these applications, expanding battery life from years to decades.

Consuming just one-third the power of comparable products in the market today, the new low-power SAM L21 family is the first on the new platform expanding the Atmel | SMART 32-bit ARM-based products using Atmel’s proprietary picoPower technology.

While running the EEMBC CoreMark benchmark, Atmel’s SAM L21 family delivers ultra-low power running down to 40µA/MHz in active mode, consuming less than 900nA with full 32kB RAM retention and real-time clock and calendar, and 200nA in the deepest sleep mode. With rapid wake-up times, Event System, Sleepwalking and the innovative picoPower peripherals, the SAM L21 ultra-low power family is ideal for handheld and battery-operated devices in a variety of markets including IoT, consumer, industrial and portable medical applications.

Architectural innovations in the new platform enables low-power peripherals including timers, serial communications and capacitive touch sensing to remain powered and running while the rest of the system is in a lower power mode, further reducing power consumption for many always-on applications.

The Atmel SAM L21 family has amazingly low current consumption ratings for both the active and sleep mode operation which will be a great benefit in targeting the growing battery-powered device market,” said Markus Levy, president and co-founder, EEMBC. “With billions of devices to be brought to market during the era of the Internet of Things, designers can utilize Atmel’s ultra-low power SAM L family to ensure an increased life in these battery-powered devices. To instantiate this power data from Atmel, I’m looking forward to seeing the results from this new platform running our newly established ULPBench, aimed at the ultra-low power microcontroller industry.”

“Atmel is committed to providing the industry’s lowest power technologies for the rapidly growing IoT market and beyond for battery-powered devices,” expained Reza Kazerounian, Atmel SVP and GM, MCU business unit. “Developers for IoT edge nodes are no longer just interested in expanding the life of a battery to one year, but are looking for technologies that will increase the life of a battery to a decade or longer. Doing just that, the new 32-bit MCU platform in the Atmel | SMART family integrating our proprietary picoPower technologies are the perfect MCUs for IoT edge nodes.”

Engineering samples of the SAM L21, along with development tools and datasheet will be available in February 2015. Meanwhile, the SAM L21 can be found all this week in Hall A5, Booth 542 at Electronica.
