The MPLAB® XC32 C/C++ Compiler is a powerful, optimizing compiler that converts your ISO C and C++ programs into high-performance, assembly-language instructions to run bare metal on our 32-bit PIC® microcontrollers and SAM microcontrollers and microprocessors. This compiler offers many command-line options and language extensions that enable full access to the device’s hardware features, including Tightly Coupled Memory (TCM), L1 cache coherence, and best-fit memory allocation.
Whether you're working on Microchip devices with 32-bit Arm®, MIPS® or PIC32A cores, the MPLAB XC32 Compiler empowers you to optimize and fine-tune your code for efficiency and minimize your development time for bare-metal or RTOS embedded applications.
Licenses
MPLAB XC32 C/C++ Compiler v5.00 Released
Upgrade to MPLAB XC32 v5.00 to leverage its significant performance, compatibility and safety improvements:
Modern GNU Compiler Collection (GCC) and Binutils Devices: MPLAB XC32 v5.00 is now based on GCC 13.2.1 and Binutils 2.41 devices that use Arm® and MIPS® cores to enable better code optimization, broader language support and tighter static analysis for safer embedded applications.
Static Analysis: Enhanced warnings catch misused memory, unsafe access patterns and logic errors in the early stages of development.
Improved Compatibility With Arm GNU Toolchain: MPLAB XC32 object files now store attributes in standard ELF sections, which improves interoperability with Arm GNU tools and other toolchains.
Device Support via Packs: Device-specific files, such as headers, linker scripts and startup code, are now delivered through Device Family Packs (DFPs), which reduces installation size by 1.4 GB and enables faster updates without a full compiler reinstall.
