    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

    Building the Programmer

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

    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)

    Before printing the PCB layout, make sure you set the "Page Scaling" value to none in the printing options window. We used the ironing method to transfer the PCB layout. Be careful and don't forget to check the thin wires between the socket pins before etching.

    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.

    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.
