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

For the PIC16F639 20-pin header, you will need to connect the jumper J3 as specified below.

N/A1-2Run/program as production device
In-circuit debuggers,
next-generation in-circuit emulators
2-3Run/program as debug device

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

Figure: Dimensions – AC162066 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.
