SAMC20/21 Arm® Cortex®-M0+ MCUs

SAMC20/21 Arm® Cortex®-M0+ MCUs

A rich set of peripherals, migration flexibility, and ease-of-use make the Microchip SAMC20 Arm Cortex-M0+ based microcontroller series ideal for a wide range of consumer, industrial, and other applications. SAMC20 and C21 devices are designed for migration between all SAM C devices to help with the design process.

These devices include identical peripheral modules, hex-compatible code, and a linear address map to the SAM C family. The SAM C20 family allows the user to migrate in the range of 10-20 ADC channels, 32 KB to 256 KB Flash, and 32- to 64-pin packages. Additional options in the SAMC21 include a 16-bit SDADC as well as CAN and SERCOM communication.
