PICDEM-3 Low-Cost PIC16CXXX Demonstration Board
PICDEM-14A Low-Cost PIC14C000 Demonstration Board
The PICDEM-3 is a simple demonstration board that supports the PIC16C923 and PIC16C924
in the PLCC package. It will also support future 44-pin PLCC microcontrollers that have an
LCD Module. All the necessary hardware and software is included to run the basic dem-
onstration programs. The user can program the sample microcontrollers, provided with
the PICDEM-3 board, on a PRO MATE II programmer or PICSTART Plus with an adapter
socket, and easily test firmware. The PICMASTER emulator may also be used with the
PICDEM-3 board to test firmware. Additional prototype area has been provided for adding hard-
ware. Some of the features include an RS-232 interface, push-button switches, a potentiometer
for simulated analog input, a thermistor and separate headers for connection to an external LCD
module and a keypad. Also provided on the PICDEM-3 board is an LCD panel, with 4 commons
and 12 segments, that is capable of displaying time, temperature and day of the week. The PIC-
DEM-3 provides an additional RS-232 interface and Windows 3.1 software for showing the
de-multiplexed LCD signals on a PC. A simple serial interface allows the user to construct a hard-
ware de-multiplexer for the LCD signals.
The PICDEM-14A demo board is a general purpose platform which is provided to help evaluate
the PIC14C000 mixed signal microcontroller. The board runs a PIC14C000 measuring the volt-
age of a potentiometer and the on-chip temperature sensor. The voltages are then calibrated to
the internal bandgap voltage reference. The voltage and temperature data are then transmitted
to the RS-232 port. This data can be displayed using a terminal emulation program, such as Win-
dows Terminal. This demo board also includes peripherals that allow users to display data on an
LCD panel, read from and write to a serial EEPROM, and prototype custom circuitry to interface
to the microcontroller.
