PIC and EEPROM Programmer

PIC and EEPROM Programmer

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.

PIC and EEPROM Programmer Printed Board

Assembling the components is straightforward. The only trick is shown in the photo. Before soldering the 40 pin socket, you must cut the plastic bridges between the sides. Another issue, don't forget to solder the diode (D6) and the jumper under the sockets first.

PIC and EEPROM Programmer Cutting the Socket

Here is the final. If you don't miss any short-circuits, you will see the red LED will bright up when you connect the programmer to the serial port. Now it is ready to use. You may use ICPROG and WinPIC to start programming your PICs or EEPROMs.

LED Indications; Yellow:Clock , Red:Power , Green:Program

Placement
Placement is shown in the figure below.
Don't forget! Wrong placement may defect your IC, programmer or computer.
You may use a ZIF socket instead according to your needs.
