Product Description


    Serial eeproms are finding more and more use in electronic devices these days. These small 8 pin devices offer non-volatile data storage and require minimal I/O lines to connect to them. This makes them ideal in many microcontroller based applications.

    The programmer connects to the PC parallel port and is controlled by driver software running on the PC. The software is DOS based but will run under Windows 3.1, Windows 9x and Windows NT4(service pack5)

    EEPROM Programmer Kit

    The programmer requires a 9 to 12VDC supply at 50mA. A 12VDC/150mA adaptor will be fine. The PCB dimensions are small 6 x 5.5cm (2.4" x 2.2") Provision is made on the PCB to use a 16 pin ZIF socket for volume programming. ZIF Socket is not supplied with the kit. The 24xxx series eeproms use the top half of the programming socket while the 93xxx series use the bottom half.

    (generic part numbers are used)
    * 2401, 2402, 2404, 2408, 2416
    * 2432, 2464, 24128, 24256
    * 9346, 9356, 9366, 9376, 9386

    The circuit is very simple. All signal levels to the eeprom are generated by the PC driver software via the parallel port and IC1 (74LS05). Transistor Q1 switches power to the eeprom and is controlled by the D3 output from the parallel port. LED L1 indicates when power is applied to the eeprom.

    We have supplied a 16 pin IC socket for the programming socket, SKT.. If you do mass production then we have made space for a 16 pin ZIF socket.

    LED L2 indicates when power is connected to the programmer.
