PIC and EEPROM Programmer




Project Summary

In this project we are building a JDM programmer that can handle PIC12, PIC16 and PIC18 family microcontrollers and some popular 24C family EEPROMs.

The programmer also provides ICSP feature that allows In-Circuit Serial Programming. So if you desire, you will not have to carry your MCU each time when you reprogram it. The circuit is connected to the PC via serial port and no external power supply is needed. On the other hand, if you want to use it with a laptop that do not provide RS232 connection, using the circuit with a USB to RS232 converter may not give a proper result

programmer

As you see the circuitry contains a few components listed below.

T1, T2 : BC337 Transistor
D1, D4, D5, D6 : 1N4148 Diode
D3 : 6V2 Zener Diode
D2 : 5V1 Zener Diode
R3, R4 : 1K8 1/4W Resistor
R1 : 10K 1/4W Resistor
R2 : 1K5 1/4W Resistor
X1 : DB9 PCB Mount Female Connector
C1, C2 : 100uF 16V Electrolytic Capacitor
SV1 and SV4 : 40 Pin Machine Tooled IC Socket
SV2, SV3 : 20 Pin Machine Tooled IC Socket
SV5 (ICSP) : 6 Pin Header Connector9
L1, L2, L3 : LED (L1: GREEN, L2: RED, L3: YELLOW)
