SMART ARM-Based Microcontrollers
SAM C21E / SAM C21G / SAM C21J
DATASHEET PRELIMINARY
Introduction
The Atmel® | SMART™ SAM C21 is a series of microcontrollers optimized for
industrial automation, appliances and other 5V applications using the 32-bit
ARM® Cortex®-M0+ processor, ranging from 32- to 64-pins with up to 256KB
Flash and 32KB of SRAM and operate at a maximum frequency of 48MHz
and reach 2.46 CoreMark®/MHz. The SAM C21 devices 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, Atmel Event System for inter-peripheral
signaling, and support for capacitive touch button, slider and wheel user
interfaces.
SAM C21 devices are pin compatible to the SAM D family of general
purpose microcontrollers.
