Header Identification

The AC number is used for ordering the Processor Extension Pak, which contains the debug header. However, this number is not on the header, as the board may be used for multiple headers by inserting different -ICE/-ICD devices. To identify these headers, use the following information.

Header Setup and Operation - AC162062

For this header, there are no jumpers/switches. MPLAB^® X IDE will use its selected device to choose the correct device to emulate.

Test points are available on this header to check the following: Vdd, Vddcore and ground.

	CAUTION
	Header Damage. This header cannot be plugged directly into the PICDEM™ HPC Explorer Board! Device damage will result.

The PICDEM™ HPC Explorer Board is 5V, whereas the ICD device on the header is 3.6V max. Therefore, modification to the demo board is necessary before the header can be used.

1. Switch S3 should be set to ICE.
2. Jumper J2 must be connected as shown in the figure to modify the operating voltage. See demo board documentation for more information.

Header Setup and Operation – AC162079, AC162087, AC162091

For these headers, there are no jumpers/switches. MPLAB^® X IDE will use its selected device to choose the correct device to emulate.

Test points are available on this header to check the following: Vdd, Vddcore and ground.

Header Limitations

Sometimes a header device (-ICE/-ICD) has operational issues or errata. To determine if a device on a header has limitations, see your hardware tool documentation.

Header Dimensions

The figure below lists the dimensions for the debug header. Dimensions are design values in inches.

If the length and/or width of the debug header is too large a footprint for the target board, consider using stand-offs, transition sockets or other extenders in the header connection socket to raise the header above the target.
