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
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.
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 figures below lists the dimensions for the debug headers. Dimensions are design values in inches.
For this device family, header AC162065 will be sold until depleted. Then only header AC244022 will remain as a Performance Pak.
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 (28 Pin) – AC162065
