What’s new in Atmel’s ARM MCU? picoPower!!

The SAM4L it is the first ARM device to feature Atmel’s picoPower technology, and takes low power to a new level.   There are many different characteristics that make a low power device; foremost it is the active power, the wake-up time and sleep mode power consumption. For the SAM4L, this can go down to 90 µA/MHz in active, down to 700 nA in sleep mode and down to 1.5 µs wake-up. Additionally the Cortex-M4 and Atmel’s fast flash technology allows your application to spend a shorter amount of time in active and spend more time in low power modes. All of this significantly reduces the total power consumption for your application.

picopower explained

Atmel SAM4L MCUs redefine the power benchmark, delivering the lowest power in both active (90uA/MHz) and sleep
modes (1.5uA with full random access memory (RAM) retention and 700nA in backup mode). They are the most efficient
MCUs available today, achieving up to 28 CoreMark™/mA using the IAR Embedded Workbench, version 6.40.
