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.
