SMART ARM-based Microcontroller
SAM L21E / SAM L21G / SAM L21J
DATASHEET PRELIMINARY
Introduction
Atmel® | SMART SAM L21 is a series of Ultra low-power microcontrollers
using the 32-bit ARM® Cortex®-M0+ processor at max. 48MHz (2.46
CoreMark®/MHz) and up to 256KB Flash and 44KB of SRAM in a 32-64 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.
