Microchips 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

* Production and post-production products can be re-flashed with firmware updates


The PICkit 3 Debug Express includes

* PICkit 3 Debugger/Programmer

* 44-pin demo board with a PIC18F45k20 microcontroller

* All hookup cables

* and a CDROM that includes the following:

.. PICkit 3 Users Guide

.. A series of 12 Lessons on assembly programming that cover I/O, A/D converters, timers, interrupts, and data tables (All source code files are provided)

.. A Debugging Tutorial on using the PICkit 3 as a debugger with the MPLAB IDE

.. A FREE CCS compiler for the PIC18F45k20. (2kWord Program Limit).

.. HI-TECH PICC LITE C Compiler.

.. Microchips MPLAB IDE software for a complete code development environment


The MPLAB PICkit 3 allows debugging and programming of PICŪ and dsPICŪ Flash microcontrollers at a most affordable price point using the powerful graphical user interface of the MPLAB 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.

* Freeze-peripherals at breakpoint


Header 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.
