MPLAB®ICD 2 In-Circuit Debugger/Programmer

In-Circuit Debugging Basics

Traditionally,embedded systems engineers use in-circuitemulators (ICE) to develop and debug their designs andthen programmers to transfer the code to the devices. Thein-circuit debugging logic,when implemented,is part of theactual microcontroller silicon and provides a low-costalternative to a more expensive ICE. In-circuit debuggingoffers these benefits:·Low cost

·Minimum of extra hardware

·Expensive sockets or adapters are not needed

·Debugging and programming a production line board ispossible

However,it has the following trade-offs:

·Use of some target system resources such as I/Opins,program memory,data memory,and stackspace. As a result,some portions of an embeddedapplication may not be debugged.

·Triggering and breakpointing are limited to the built-incapabilities of the in-circuit debugging logic.

·The target chip must be running with a clock and asupply voltage. Often an emulator probe can run

without external hardware.

Features

·USB (Full Speed 2 Mbits/s) and RS-232 interface tohost PC·Real-time execution

·MPLAB IDE compatible (free copy included)·Built-in over voltage/short circuit monitor·Firmware upgradeable from PC/web download·Totally enclosed

·Supports low voltage to 2.0 volts (2.0 to 6.0 range)·Diagnostic LED's (Power,Busy,Error)·Read/Write program and data memory ofmicrocontroller·Erase of program memory space with verification·Freeze-peripherals at breakpoint

All-in-one Debugger/ProgrammerSolution for Flash Products

The MPLAB ICD 2 (In-Circuit Debugger 2) allows

debugging and programming of PIC®and dsPIC®Flash

microcontrollers using the powerful graphical user interfaceof the MPLAB Integrated Development Environment (IDE),included with each kit. The MPLAB ICD 2 is connected tothe design engineer's PC using USB or RS-232 interfaceand can be connected to the target via an ICD connector.The connector uses two device I/O pins that are sharedbetween in-circuit debugging and In-Circuit SerialProgramming .

ProductsSupported

The MPLABICD2 currently supports most PIC and dsPICFlash microcontrollers. Flash PICmicro MCU’s notsupported are PIC16F72/73/74/76/77/83/84A.

The MPLAB ICD 2 firmware is continually being updated toadd support for new devices. A review of the README filelocated in MPLABIDE is recommended for the most currentlist of supported parts. As new device firmware becomesavailable,free downloads are available .

Host System Requirements

·PC-compatible system with a Intel Pentium®class orhigher processor,or equivalent·A minimum of 32 MB RAM

·A minimum of 40 MB available hard drive space·CD-ROM drive (for use with the accompanying CD)·Available USB or RS-232 port

·Microsoft®Windows®98,Windows NT®4.0,Windows 2000 or Windows XP. USB support may belimited by the Windows operating system,particularlyWindows 98/NT.
