PIC18F87K22 Plug-in Module for PICDEM™ PIC18 Explorer Board
Overview
The PIC18F87K22 Plug-in Module (PIM) is an accessory to the PICDEM™ PIC18
Explorer Board that allows users to easily experiment with the PIC18F87K22 family of
microcontrollers. PIC18F87K22 is the superset member of the family and this PIM can
be used to evaluate and develop with the PIC18F87K22 products. The PIM takes the
place of the on-board PIC18F8722 device, and changes the output of the voltage regu-
lator on the board to the proper voltage level for these parts. This enables users to
quickly evaluate the new PIC18FK Flash devices without having to buy a completely
new demo board.
Getting Started with the PIM
1. Make sure the on-board PIC18F87K22 is programmed to allow the MCLR Reset
2. Verify that the PICDEM PIC18 Explorer Board is not powered.
3. Set switch, S4, to the “ICE” position. This will hold the on-board PIC18F8722 in
4. Line up the PIM so its 3-pin female header aligns with the 3-pin riser on the
5. Apply power to the demo board. Be sure that V
Changes to PICDEM PIC18 Explorer Board Configuration
The difference of available I/O pins between the PICDEM PIC18 Explorer Board’s
PIC18F8722 device and the PIM’s PIC18F87K22 device causes some changes in the
operation of the PICDEM PIC18 Explorer Board.
1. Most I/O lines connected to the PICDEM PIC18 Explorer Board’s PICtail connector,
2. Port I/O pin, RF0, will be left unconnected because this pin does not exist on the
3. The PIC18F87K22 can operate between 1.8V and 5V. The supplied voltage can be
Bootloader Firmware
This PIM comes preprogrammed with firmware from the “High-Speed Serial
Bootloader for PIC16 and PIC18 Devices” (AN1310), which can be used to reprogram
the device without requiring a dedicated PIC
installation package and AN1310 application note documentation may be downloaded
from the Microchip web site.
Demonstration Firmware
Additionally, the PIM is programmed with firmware demonstrating basic features on the
PIC18 Explorer Board. The source for the PIC18F87K22 PIM demo code may be
downloaded from the Microchip web site.

purpose I/O, the on-board PIC18F8722 may interfere with PIM usage, even when
the board is switched to ICE mode.

used (5V for PIC18F87K22). If it is not correct, disconnect power and check that
the 3-pin female header is aligned properly with the demo board’s 3-pin riser.
