Header Specification
MPLAB^® ICD 2
INTRODUCTION
This document contains information about MPLAB^® ICD 2 headers, which provide
in-circuit debugging capabilities for specific Microchip devices.
A special ICD/ICE device is connected to a header board to be used with MPLAB ICD 2.
This device is mounted on the top of a header and its signals are routed to the
MPLAB ICD 2 connector (Figure 1). On the bottom of the header is a socket that is
used to connect to the target board.

Target Application
Special ICD/ICE versions of selected devices are needed to provide one or more of the
following:
• the built-in debug circuitry that a device may lack
• additional pins for the clock, data and MCLR functions required for ICD
• dedicated program/data memory for ICD
ICD versions are labeled with an ICD suffix (Device-ICD). For some devices, ICE
versions are available (Device-ICE) and may be used with MPLAB ICD 2 as ICD
devices.
