ATSAMC21J18A-AUT Microchip 32bit MCU

ATSAMC21J18A-AUT Overview

The Microchip SAM C series of 5V Cortex M0+devices is designed for industrial and commercial applications in noisyenvironments. These products feature robust communications peripheralsincluding the SERCOM module and CAN-FD, along with advanced motor controlperipherals, and the Peripheral Touch Control (PTC) for developing robust userinterfaces.

Supported by MPLAB X IDE and MPLAB Harmony.
