SAM D21E / SAM D21G /SAM D21J Summary

Introduction

The SAM D21 is a series of low-power microcontrollers using the 32-bit ARM

® Cortex®-M0+ processor,

and ranging from 32- to 64-pins with up to 256KB Flash and 32KB of SRAM. The SAM D21 operate at a

maximum frequency of 48MHz and reach 2.46 CoreMark

®/MHz. They are designed for simple and

intuitive migration with identical peripheral modules, hex compatible code, identical linear address map

and pin compatible migration paths between all devices in the product series. All devices include

intelligent and flexible peripherals, Event System for inter-peripheral signaling, and support for capacitive

touch button, slider and wheel user interfaces.
