Compiler Requirements for MPLAB® X IDE

Last modified by Microchip on 2025/05/02 07:11

The MPASM™ assembler toolchain is a 32-bit application and is no longer installed with MPLAB^® X IDE starting with v5.40. This means no toolchain will be available by default when MPLAB X IDE is installed for the first time. Here is a list of supported compilers and assemblers from which to choose.

Supported Compilers and Assemblers

Compiler	Toolchain	64-bit Only Version
MPLAB XC8	XC8	2.05 and later
PIC^® Assembler¹	XC8	2.05 and later
MPLAB XC16	XC16	1.50 and later
MPLAB XC-DSC	XC-DSC	3.00 and later
MPLAB XC32/XC32++	XC32	2.40 and later
Arm^® GNU	Arm GNU	5.3.1 and later
AVR^® GNU	AVR GNU	3.4.3 and later
AVR Assembler²	AVRASM2	2.2.6 and later
