Introduction

PIC32CM devices are a family of 32-bit microcontrollers (MCUs) from Microchip Technology, based on the Arm® Cortex®-M0+ and M23 cores. These devices offer higher performance, more memory, and advanced peripherals compared to traditional 8-bit microcontrollers, such as the AVR® family. This document provides a comprehensive comparison of various features across the AVR and PIC32CM device families, helping users decide whether a PIC32CM device family can serve as an alternative solution to AVR. If users choose a PIC32CM MCU, this document helps ease the migration process by associating concepts between AVR and PIC32CM. Users can then refer to the Migration Guide from AVR and PIC16/18F to PIC32CM Development Tools Ecosystem for a comprehensive comparison of the tools. These documents also provide links to other PIC32CM “Getting Started” documents for additional reference.
