IAR Embedded Workbench vs MPLAB X IDE

IAR Embedded Workbench is an embedded development toolchain with an IDE, optimizing compiler, linker, assembler, and debugger. It supports over 20 architectures, including Arm, RISC-V, 8051, MSP430, AVR, and several Renesas families. The C-SPY debugger provides real-time trace, code coverage, function profiling, and RTOS awareness. IAR C-STAT offers static analysis; IAR C-RUN detects runtime errors and is available for Arm and RX. The toolchain works with VS Code and Eclipse, supports CMake builds, and can integrate with CI/CD pipelines. Supported debug probes include I-jet, I-jet Trace, J-Link, PE Micro, and ST-LINK. Built-in plugins provide RTOS awareness for systems including PX5 RTOS and Zephyr RTOS. The IDE runs natively on Linux and Windows. A 14-day evaluation is available for non-commercial use, but excludes runtime library source code, C-STAT, and MISRA C support and includes limited technical support. Paid subscription pricing is available by request; the subscription combines named-user licenses and build capacity for automated builds and CI/CD.

MPLAB X IDE is a free desktop environment for discovering, configuring, developing, debugging, and qualifying embedded designs for most Microchip microcontrollers and digital signal controllers. It runs on Windows, Linux, and macOS, supporting 64-bit Intel or AMD computers and Arm-based Apple silicon. During debugging, I/O View can display and manipulate target registers. A single action can build a project, connect to a hardware tool, program the target, and begin debugging or execution. Data Visualizer displays real-time streaming data, and MPLAB Integrated Programming Environment supports production-level programming. The IDE supports open-source AVR and SAM MCU GCC and can work with MPLAB XC compilers. Projects and tools such as Code Configurator and Data Visualizer are also supported in Microsoft Visual Studio Code. Source control configuration options and a plug-in manager, including support for NetBeans plugins, extend the environment. The listed 6.35 release supports Windows, Linux, and macOS. Version 6.20 was the last release supporting PICkit 3, MPLAB ICD 3, and MPLAB REAL ICE. Supported targets include PIC, dsPIC, AVR, SAM, PIC32, and other Microchip MCU, DSC, and MPU families.
