Microchip Technology 32-Bit SAM C Microcontrollers

Microchip Technology 32-Bit SAM C Microcontrollers are optimized for industrial automation, appliances, and other 5V applications using the 32-bit Arm® Cortex®-M0+ processor. The SAM C MCUs range from 32- to 64-pins with up to 256KB Flash and 32KB of SRAM. These devices operate at a maximum frequency of 48MHz and reach 2.46 CoreMark®/MHz. The SAM C 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, Microchip Event System for inter-peripheral signaling, and support for capacitive touch buttons, sliders, and wheel user interfaces. Microchip Technology SAM C MCUs are pin-compatible to the SAM D and SAM C family of general-purpose microcontrollers.
