Microchip PIC32CM JH Series – 5V Cortex®-M0+ Microcontrollers

Reliable performance for automotive, industrial, and other noise-prone environments

The Microchip PIC32CM JH series of 5V Arm® Cortex®-M0+ microcontrollers delivers reliable performance in noisy environments, making it ideal for automotive, industrial, and safety-critical applications.

With built-in functional safety features such as mBIST, secure boot support, and compatibility with external security ICs, the PIC32CM JH series ensures system integrity and protection. A rich set of peripherals including CAN-FD, advanced touch control with Driven Shield Plus, high-speed ADCs, and multiple communication interfaces enables versatile design options.

Supported by the MPLAB® X IDE and Harmony framework, these MCUs offer developers a robust, efficient, and secure platform for next-generation embedded solutions.
