Optional Debug Headers

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
Both 28-pin and 44-pin device headers have jumpers related to the enabling or dis-
abling of the on-chip 2.5 volt voltage regulator. Please see the section entitled “On-Chip
Voltage Regulator” in the dsPIC33F Family Reference Manual (DS70165) for more
details.
Test points are available on this header to check the following:
Header Limitations
Sometimes a header device (-ICE/-ICD) has operational issues or errata. To determine
whether a device on a header has limitations, see your hardware tool documentation.
Header Dimensions
The following figures list the dimensions for the debug headers. 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.
