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.
Features
• Processor
– ARM Cortex-M0+ CPU running at up to 48MHz
• Single-cycle hardware multiplier
• Micro Trace Buffer
• Memories

– 1/2/4/8KB Flash Read-While-Write section
– 4/8/16/32KB SRAM Main Memory
– 2/4/8/8KB SRAM Low power Memory
• System
– Power-on reset (POR) and brown-out detection (BOD)
– Internal and external clock options
– External Interrupt Controller (EIC)
– 16 external interrupts
– One non-maskable interrupt
– Two-pin Serial Wire Debug (SWD) programming, test and
debugging interface
• Low Power
– Idle, Standby, Backup, and Off sleep modes
– SleepWalking peripherals
