SAM L21 Family Data Sheet SAM L21 Introduction Atmel® SMART SAM L21 is a series of ultra-low power microcontrollers using 32-bit Arm® Cortex®-M0+ processor at maximum 48 MHz (2.46 CoreMark®/MHz) and up to 256 KB Flash and 40 KB of SRAM in a 32-pin, 48-pin, and 64-pin packages. The sophisticated power management technologies, such as power domain gating, SleepWalking, ultra-low power peripherals allow very low-power 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 48 MHz • Single-cycle hardware multiplier • Micro Trace Buffer • Memories – 32/64/128/256-KB in-system self-programmable Flash – 1/2/4/8-KB Flash Read-While-Write section – 4/8/16/32-KB SRAM main memory – 2/4/8/8-KB SRAM low-power memory • System – Power-on Reset (POR) and Brown-out Detection (BOD) – Internal and external clock options – External Interrupt Controller (EIC) – 16 extern.
