SAM C21 MCU Overview
A rich set of peripherals, flexibility, and ease-of-use combined with 2.7 V – 5.5 V operating voltage make the Microchip SAM C21 Arm® Cortex®-M0+ based microcontroller series ideal for a wide range of consumer and industrial applications. SAM C21 devices are designed for simple and intuitive migration between SAM C devices with identical peripheral modules, compatible code, and a linear address map.
