  • 24C16A EEPROM programmer

    I have some 24C16A to program. I have a working 24C16A to clone.

    What is a fast and cheap way to proceed? I need a software and an
    hardware interface (USB to IIC or RS232 to IIC).

    I have a PicKit2, but I'm not sure if they can be used to program IIC
    EEPROM. If yes, what is the software to use?

    I could write a simple firmware for an MCU with IIC that connects to a
    PC (via RS232 or USB), but I don't want to spend so much time for this task. --- Synchronet 3.20a-Linux NewsLink 1.114

    Do you have a Raspberry Pi?

    You'd have to check support for the 24C16A, but it's simple to run Flashrom
    on the Pi, using GPIOs to talk to the chip. You just need to lash up some wires.

    I've made some jigs for BIOS flashes like this, and then it's a couple of commands to read and write.
