PICKIT 3 PROGRAMMER/DEBUGGER DEFINED
The PICkit 3 programmer/debugger (see Figure 1-1) is a simple, low-cost in-circuit
debugger that is controlled by a PC running MPLAB IDE (v8.20 or greater) software on
a Windows ? platform. The PICkit 3 programmer/debugger is an integral part of the
development engineer ’s toolsuite. The application usage can vary from software
development to hardware integration.
The PICkit 3 programmer/debugger is a debugger system used for hardware and
software development of Microchip PIC ? microcontrollers (MCUs) and dsPIC ? Digital
Signal Controllers (DSCs) that are based on In-Circuit Serial Programming? (ICSP?)
and Enhanced In-Circuit Serial Programming 2-wire serial interfaces. In addition to
debugger functions, the PICkit 3 programmer/debugger system also may be used as a
development programmer.
The debugger system executes code like an actual device because it uses a device
with built-in emulation circuitry, instead of a special debugger chip, for emulation. All
available features of a given device are accessible interactively, and can be set and
modified by the MPLAB IDE interface.
The PICkit 3 debugger was developed for emulating embedded processors with debug
facilities. The PICkit 3 features include:

The PICkit 3 is intended for development programming. For production
programming, please consider the MPLAB PM3 device programmer or
other third party programmers designed for a production environment.
