    SAM L21 Family Data Sheet
    Introduction
    В® В® В® Atmel | SMART SAM L21 is a series of Ultra low-power microcontrollers using the 32-bit ARM Cortex В®
    M0+ processor at max. 48MHz (2.46 CoreMark /MHz) and up to 256KB Flash and 40KB of SRAM in a
    32, 48, and 64 pin package. The sophisticated power management technologies, such as power domain
    gating, SleepWalking, Ultra low-power peripherals and more, allow for very low current consumptions.
    The highly configurable peripherals include a touch controller supporting capacitive interfaces with
    proximity sensing. Features Processor
