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.
|AC Number||-ICE/-ICD Device||Board Assembly Number|
Header Setup and Operation - AC162053
For this headers, there are no jumpers/switches. The device with the most program memory is always selected.
If PIC16F627A or PIC16F628A devices are selected for development in MPLAB X IDE, the warning “Invalid target device ID” may be received in the build window. Ignore this warning. The reason for the warning is that the PIC16F648A-ICD device supports PIC16F648A, PIC16F627A and PIC16F628A, but only reports the device ID for the PIC16F648A.
Header Setup and Operation – AC162054
This header supports one device (PIC16F716) so there are no jumpers or switches.
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.
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.Figure: Dimensions – AC162053, AC162054
