Overview
The ATSAML21G16B-AUT is an ultra-low power ARM Cortex-M0+ based microcontroller from Microchip's SAM L series. It features 128KB of Flash and 24KB of SRAM, operating at speeds up to 48MHz while maintaining industry-leading power consumption metrics.
Why Choose This Part
This MCU stands out for its sophisticated power management system, including multiple power domains and a low-power peripheral system (SleepWalking). It achieves current consumption as low as 35 uA/MHz in active mode and less than 900 nA in RAM retention standby mode.
Applications
Battery-Powered Wearables
Ideal for fitness trackers and smart watches where extending battery life between charges is a critical design requirement.
Environmental Sensing
Suitable for remote IoT sensor nodes that must run for years on a single coin-cell battery or energy harvesting source.
Smart Utility Meters
Provides the necessary processing power for metrology and communication while minimizing the standby current draw.
Getting Started
Engineers can begin development using the SAM L21 Xplained Pro evaluation kit (ATSAML21-XPRO). Software development is supported by Atmel Studio 7 and the Atmel Start web-based configuration tool for rapid peripheral initialization.
