Atmel’s ultra-low-power SAM L family of 32-bit, ARM Cortex-M based microcontrollers (MCU) consume just 35 μA/MHz in active mode and 200 nA in sleep mode. The SAM L21 boasts Flash and SRAM that are large enough to run both the application and wireless stacks, making it well suited for Internet of Things (IoT) applications. Achieving a score of 185 in the EEMBC ULPBench benchmark, the devices consume less than 940 nA with full 40 KB SRAM retention, real-time clock and calendar, and 200 nA in the deepest sleep mode.
The chip’s peripherals support Sleepwalking, a technology that enables them to request a clock when needed to wake up from sleep modes and perform tasks without having to power up the CPU Flash and other support systems.
