AC162088, AC162094

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
AC162088 PIC24FJ64GA004-ICE 02-01979
AC162094 02-01982

Header Setup and Operation

Both 28-pin and 44-pin device headers have jumpers related to the enabling or disabling 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.

Jumper Function
1-2 Disable voltage regulator
2-3 Enable voltage regulator
No connection DISVREG controlled by target

Test points are available on this header to check the following:

Test Point Color Signal Test Point Color Signal
TP1 Black Ground TP5 White DISVREG
TP2 Red Vdd TP6 White PGC
TP3 Black AVss TP7 White PGD
TP4 Red AVdd TP8 Yellow ICRST

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.
