Summary
This low-cost demo board is the ideal complement to the
MPLAB® ICD 2 In Circuit Debugger to evaluate the
performance of Microchip high-end 8-bit microcontrollers of
the PIC18F series.
The board features a PIC18F8722
microcontroller, which is the superset of the entire 64- and
80-pin PIC18FXXXX general purpose family. A daughter board
(mezzanine) is also part of the kit and allows different
processors sharing the same pin out to be mounted and tested
on the Explorer board.
The same connector allows MPLAB ICE
4000 (and via an extension MPLAB ICE 2000) real-time
in-circuit emulators to be attached to the board.
Features
- PIC18F8722, 128K Flash, 80-pin TQFP microcontroller
- Full pin break-out for easy wire wrap/prototyping,
- Daughter board and MPLAB ICE2000/4000 connector (with
switch to disable on board processor)
- 10 MHz crystal oscillator (to be used with internal PLL
to provide 40 MHz operation)
- Convenient connection for MPLAB ICD 2 (In-Circuit
Debugger) for in-circuit programming and debugging
- Power supply connector and programmable voltage
regulator, capable of operation from 2.0 to 5.5V (requires
any standard 9-12V power supply, also available separately)
- Potentiometer (connected to 10-bit A/D, analog input
channel)
- Temperature sensor demo included (illustrates
Microchip’s award winning TC74 device)
- 8 LEDs (connected to PORTD with jumper disable)
- RS-232 port (9 pin D type connector, UART1)
- Reset button
- Bootloader button
- PICtail ™ daughter board connector, to allow connection
to standard expansion boards
- Serial bootloader ready (see AN851)
- 32 kHz crystal for Real Time Clock
