XC32

XC32 is a C and C++ compiler toolchain for Microchip Technology's PIC32 family of 32-bit microcontrollers. It is the 32-bit member of Microchip's XC compiler line, alongside XC8 and XC16, and is built around the GNU Compiler Collection with Microchip-specific optimizations and code-generation enhancements. The toolchain targets a range of PIC32 devices, including PIC32MX and PIC32MZ families, and supports standard C and C++, along with processor-specific intrinsics and inline assembly. It integrates with Microchip development environments and can be used as a standalone cross-compiler.

As a GCC-based embedded toolchain, XC32 provides features common to embedded compilers: support for building bare-metal firmware, linker scripts and startup code, interrupt handling, and access to device headers and libraries supplied by Microchip. It offers various optimization levels and debugging support through compatible debuggers, and it works with Microchip runtime libraries and middleware designed for PIC32 devices.

XC32 is distributed by Microchip as part of its compiler suite and is available with a licensing model that includes free evaluation and commercial licenses for professional development. It is regularly updated to add device support, performance improvements, and compatibility with new PIC32 devices and the MPLAB X ecosystem.

In the Microchip toolchain ecosystem, XC32 complements the XC8 and XC16 compilers and is designed to work with MPLAB X IDE, MPLAB Code Configurator, and related software to support a broad range of PIC32-based projects.
