Microchip ATSAMC20J18A-MNT

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

Supported by MPLAB X IDE and MPLAB Harmony.
