MPLAB® PICkit™ 4 User’s Guide DS50002751B-pMicrochip Technology Inc. The PICkit 4 supports advanced interfaces like 4-wire JTAG and Serial Wire Debug with streaming Data Gateway. Watch headings for an "edit" link when available. Change the name (also URL address, possibly the category) of the page. MPLAB PICkit 4 In-Circuit Debugger Part Number: PG164140 Summary: Fast programming, increased functionality, at the same price as its predecessor, the PICkit™ 3. However, when debugging these devices the header must be used.AVR is expected soon! View/set parent page (used for creating breadcrumbs and structured layout). The header board is not used or needed for programming. This special MCU has extra pins for PICkit 3 communication and therefore allows the use of all pins on the part for the application. Some 8-, 14-, and 18-pin devices use small header boards with a special MCU for debugging. For older software for programming with the PICkit 3, please visit Microchip's archives. The connector uses two device I/O pins and the reset line to implement in-circuit debugging and In-Circuit Serial Programming™. 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 a Microchip debug (RJ-11) connector (compatible with MPLAB ICD 2, MPLAB ICD 3, and MPLAB REAL ICE).

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). It should be used for development purposes only. The PICkit 3 in-circuit debugger/programmer is not a production programmer.

The PICkit 3 can also reprogram any PIC ® microcontroller with a simple push of a button. Expensive sockets or adapters are also not required.

In-circuit debugging offers benefits including low cost and a minimum of additional hardware needed for debug. 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.
