What is PICkit 3 Programmer?
PICkit 3 programmer/debugger 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 PICkit 3 programmer/debugger is not intended to be used as a production programmer.

PICkit 3 Programmer Circuitry and Connector Pinouts
PICkit 3 Programmer Recommend Component Settings:

Supplied by target
|Disabled (device dependent)
|Table Read Protect Disabled
VDD > BOD VDD min
|AVDD and AVSS
|Must be connected
Proper channel selected, if
|VDD voltage levels meet
PICkit 3 Programmer Target Circuit Design Precautions:
- Do not use greater than 100 µF capacitance on VDD: dependingon the overall load, it will prevent the target from powering quicklywhen PICkit 3 is the source of power.
• Do not use capacitors on MCLR: they will prevent fast transitions of VPP.
• Do not use pull-ups on PGC/PGD: they will divide the voltage levels since these lines have 4.7 kΩ pull-down resistors in PICkit 3.
• Do not use multiplexing on PGC/PGD: they are dedicated for communications to PICkit 3.
• Do not use capacitors on PGC/PGD: they will prevent fast transitions on data and clock lines during programming and debug communications.
• Do not use diodes on PGC/PGD: they will prevent bidirectional communication between PICkit 3 and the target PIC®MCU.
• Do not exceed recommended cable lengths: refer to the Hardware Specification section of the PICkit 3 online help or user’s guide for acceptable cable lengths.
