AC244035, AC244036

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
AC244035 PIC16F1939-ICE 02-02105
AC244036 PIC16LF1939-ICE

Header Setup and Operation

For this header, you will need to set up the jumpers below.

Jumper Setting Function
J2 Open Disable weak ICE/MCLR pull-up resistor.
Short Enable weak ICE/MCLR pull-up resistor.
This option keeps the target program running even after the tool
has been disconnected from the header, i.e., the pin will not
float high.
J3 Open Disable power LED indicator. This option saves power.
Short Enable power LED indicator.
J4 Open Use only target capacitance for VCAP (on RA0 pin).
Short Use both on-board and target capacitance for VCAP (on RA0 pin).
J5 Open Use only target capacitance for VCAP (on RA5 pin).
Short Use both on-board and target capacitance for VCAP (on RA5 pin).
J6 Open Use only target capacitance for VCAP (on RA6 pin).
Short Use both on-board and target capacitance for VCAP (on RA6 pin).

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 accompanying figure 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.
