Development Boards
PICDEM-1 Low-Cost PIC16/17 Demonstration Board
PICDEM-2 Low-Cost PIC16CXXX Demonstration Board
Development boards give a quick start on a circuit that demonstrates the capabilities of a partic-
ular device. The device program can then be modified for your own evaluation of the device func-
tionality and operation.
The PICDEM-1 is a simple board which demonstrates the capabilities of several of Microchip’s
microcontrollers. The microcontrollers supported are: PIC16C5X (PIC16C54 to PIC16C58A),
PIC16C61, PIC16C62X, PIC16C71, PIC16C710, PIC16C711, PIC16C8X, PIC17C42A,
PIC17C43 and PIC17C44. All necessary hardware and software is included to run basic demo
programs. The users can program the sample microcontrollers provided with the PICDEM-1
board, on a PRO MATE II or PICSTART-Plus programmer, and easily test firmware. The
user can also connect the PICDEM-1 board to the PICMASTER emulator and download the
firmware to the emulator for testing. Additional prototype area is available to build additional hard-
ware. Some of the features include an RS-232 interface, a potentiometer for simulated analog
input, push-button switches and eight LEDs connected to PORTB.
The PICDEM-2 is a simple demonstration board that supports the PIC16C62, PIC16C63,
PIC16C64, PIC16C65, PIC16C72, PIC16C73 and PIC16C74 microcontrollers. All the neces-
sary hardware and software is included to run the basic demonstration programs. The
user can program the sample microcontrollers provided with the PICDEM-2 board, on a
PRO MATE II programmer or PICSTART-Plus, and easily test firmware. The PICMASTER
emulator may also be used with the PICDEM-2 board to test firmware. Additional prototype area
has been provided for additional hardware. Some of the features include a RS-232 interface,
push-button switches, a potentiometer for simulated analog input, a Serial EEPROM to demon-
strate usage of the I
pad.
