- PICkit™ 3 In-Circuit Debugger is Microchip's lowest cost hardware debugger/programmer. Like the MPLAB® REAL ICE™ In-Circuit Emulator and MPLAB ICD 3, it can program and debug Microchip PIC® microcontrollers and dsPIC® digital signal controllers. Also it works seamlessly with the MPLAB X IDE.
- The PICkit 3 connects to a PC using a full-speed USB 2.0 interface and connects to the target using the same interface found on all Microchip Debugger/Programmers, an In Circuit Serial Programming (ICSP) interface.
- The PICkit 3 In-Circuit-Debugger/Programmer is NOT a production programmer. It should be used for development purposes only.
- Microchip’s PICkit™ 3 In-Circuit Debugger/Programmer uses in-circuit debugging logic incorporated into each chip with Flash memory to provide a low-cost hardware debugger and programmer. In-circuit debugging offers these benefits:
- Low cost
- Minimum of additional hardware needed for debug
- Expensive sockets or adapters are not required
- The PICkit 3 can now also reprogram any PIC microcontroller with a simple push of a button: Find out more about Programmer-To-Go function.
- The PICkit 3 In-Circuit Debugger/Programmer is NOT a production programmer. It should be used for development purposes only.
- The PICkit 3 is not recommended for new designs and no new device support will be added to it as of June 1, 2019. For new designs, please see the MPLAB PICKit 4.
- The MPLAB PICkit 3 allows debugging and programming of PIC® and dsPIC® Flash microcontrollers at a most affordable price point using the powerful graphical user interface of the MPLAB X Integrated Development Environment (IDE). The MPLAB PICkit 3 is connected to the design engineer's PC using a full speed USB interface and can be connected to the target via an Microchip debug (RJ-11) connector (compatible with MPLAB ICD 2, MPLAB ICD 3 and MPLAB REAL ICE). The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™.
- If you need older software for programming with your PICkit 3, please visit Micrichip archives.
- The MPLAB PICkit 3 supports Microchip entire portfolio of PIC and dsPIC products. Because product support of MPLAB PICkit 4, MPLAB Snap and MPLAB ICD 4 is not complete yet, MPLAB PICkit 3 may be the primary tool to support your MCU. Please consult the product support matrix available in the MPLAB X IDE help file for debugger support information.
- Some 8-, 14- and 18-pin devices use small header boards with a special MCU for debugging. This special MCU has extra pins for PICkit 3 communication and therefore allows the use of all pins on the part for the application. The header board is not used or needed for programming. However, when debugging these devices the header must be used. See the "Header Specification" document.
