MPLAB ICD 2 Header Specification 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.

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. 2005 Microchip Technology Inc. DS51292L-page 1 MPLAB ICD 2 HEADERS FOR ICD DEVICES Some devices have no built-in debug circuitry. Therefore, special ICD versions of these devices are required for MPLAB ICD 2 operation. Other devices have built-in debug circuitry and do not require a header to use MPLAB ICD 2. However, some pins and memory must be used to support the ICD function. Therefore, for some of these devices, special ICD versions offering additional pins (and sometimes memory) are available to provide more transparent debugging capabilities. Currently-available headers and their associated ICD devices/supported devices are shown in Table 1.

Move circuitry that makes GP1/RA1 high to another I/O pin during development. See device programming specifications for more information. DS51292L-page 2 2005 Microchip Technology Inc.
