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.

AC Number -ICE/-ICD Device Board Assembly Number
AC162061 PIC16F690-ICD 02-01835

Header Setup and Operation

For the PIC16F690 20-pin header, you will need to set the S1 switches shown in the figure to enable peripherals and choose devices as per the table.

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.
