 MPLAB® X Integrated Development Environment (IDE) is an expandable, highly configurable software program that incorporates powerful tools to help you discover, configure, develop, debug and qualify embedded designs for most of Microchip’s microcontrollers, microprocessors and digital signal controllers.
|
| When combined with our free and award-winning MPLAB X Integrated Development Environment (IDE), the fully graphical frontend provides:
Editing errors and breakpoints that match corresponding lines in the source code
Single stepping through C and C++ (C++ only available in MPLAB XC32++ compilers) source code to inspect variables and structures at critical points
Data structures with defined data types, including floating point, display in watch windows
|
| MPLAB Code Configurator supports 8-bit, 16-bit and 32-bit PIC® microcontrollers. MCC is incorporated into both the downloadable MPLAB X Integrated Development Environment (IDE) and the cloud-based MPLAB Xpress IDE.
|
| MPLAB® Harmony is a modular framework that provides interoperable firmware libraries for application development on 32-bit microcontrollers and microprocessors.
|
| MPLAB® Extensions for Microsoft® Visual Studio Code® (VS Code®) is a collection of VS Code extensions that combines the power of the MPLAB development ecosystem with the versatility of VS Code. Whether you are a new or existing client, MPLAB Extensions for VS Code provides you with a seamless, flexible and efficient development environment with comprehensive support for designs based on our devices.

| Atmel-ICE is a powerful development tool for debugging and programming ARM® Cortex®-M based SAM and AVR microcontrollers with on-chip debug capability.
|
| Power Debugger is a powerful development tool for debugging and programming AVR and ARM® Cortex®-M based SAM microcontrollers. In addition the Power Debugger features two independent current sensing channels and includes a CDC virtual COM port interface as well as Data Gateway Interface channels for streaming application data to the host computer from a SPI, USART, TWI or GPIO source.
|
| The MPLAB® ICD 4 In-Circuit Debugger/Programmer is Microchip’s fastest, cost-effective debugging and programming tool for PIC® Microcontrollers (MCUs), Microprocessors (MPUs) and dsPIC® Digital Signal Controllers (DSCs).
|
| J-32 Debug Probe is a JTAG/ICSP Debugger that supports all of Microchip's 32-bit MCU and MPU products.
|
| The MPLAB® Snap In-Circuit Debugger/Programmer allows affordable, fast and easy debugging and programming of PIC®, dsPIC® and AVR flash MCUs and MPUs, using the powerful graphical user interface of MPLAB X Integrated Development Environment (IDE). The MPLAB Snap can be connected to a design engineer's computer using a High-Speed USB 2.0 interface and can be connected to the target via an 8-pin Single In-Line (SIL) connector. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™ (ICSP™). It has all the speed and features entry-level users need to quickly debug their prototype.
