Although three sockets are provided, only one device may be used at a time.
• 8- or 14-pin socket (U5) used for 8- or 14-pin devices (8-pin devices are inserted
• 18-pin PIC16 socket (U7)
• 18-pin PIC18 socket (U8)
Eight red LEDs are connected to PORTA and PORTB of U7 and U8, while five of the
eight LEDs are connected to U5. PORTA and PORTB pins are set high to light the
LEDs. These LEDs may be disconnected from PORTA and PORTB by removing
jumpers J21 and J22.
One green LED is provided to determine whether there is power to the PICDEM 4
board (LED on) or not (LED off).
There are three ways to supply power to PICDEM 4:
• A 9V battery can be plugged into J2.
• A 9V, 100 mA unregulated AC or DC supply can be plugged into J1. A power
• A +5V, 100 mA regulated DC supply can be connected to the hooks provided.
MPLAB ICE 2000 users have a regulated +5V power supply available in the logic probe
connector and can easily connect to the hooks on PICDEM 4 (Red probe to +5V and
Black probe to GND).
MPLAB ICD 2 users may use the ICD to power the target board to 5V, up to 200 mA, if
the MPLAB ICD 2 is connected to the PC with a serial cable.
An RS-232 level shifting IC has been provided with all necessary hardware to support
connection of an RS-232 host through the DB9 connector. The port is configured as
DCE, and can be connected to a PC using a straight through cable.
The PIC16/PIC18 RX and TX pins are tied to the RX and TX lines of the LT1280ACN.
Unlike previous demo boards, the RS-232 chip has an ON/OFF pin which is connected
to I/O pin RB3. For RS-232 operation, these jumpers must be configured as follows:
PIC16
• J18/19 - Upper two pins ON
• J20 - OFF (if populated)
PIC18
• J18/19 - Lower two pins ON
in the upper 8 pins of U5)
supply can be purchased through Microchip, Part # AC162039.
Note 1:
2:
There are two jumpers (J3 and J4) associated with the power
supply circuit. These jumpers must be on for all functions,
with the exception of the Supercapacitor Circuit. Refer to
Section A.12 “Supercapacitor” for further details.
The PICDEM 4 kit does not include a power supply.
