ATMEL'den CORTEX M0 Low Power MCU SAM L21 (35 µA/MHz aktif, 200nA uyku)

[muuzoo]

The Atmel® | SMART SAM L21 family of microcontrollers (MCUs) delivers power consumption down to 35 µA/MHz in active mode and 200nA in Sleep mode. In addition to ultra-low-power performance, these new devices feature Full Speed USB host and device, Event System and Sleepwalking, 12-bit analog, AES, capacitive touch sensing, built in opAmps and much more. With the Internet of Things (IoT) market predicted to grow to billion devices by 2020, designers increasingly need lower-power MCUs that will enable these applications—without adding load to utility grids or requiring frequent battery changes. The new ultra-low-power Atmel® | SMART platform is specifically designed to power these applications, expanding battery life from years to decades. The preliminary datasheet is available for download now.

 ARM Cortex-M4 96Mhz MCU ile 102 µA/MHz değerine sahip. Bu MCU'ya göre 3 kat fazla olabilir ancak 48Mhz lik MSP432 Cortex M4F2nin 48 mhz olduğunu göre alırsak iyi bir değer.
