    Hi,
    I am trying to interface EPCS4 serial eeprom to 8 bit MCU. I am facing a problem in read and write or any kind of instruction used to communicate with the eeprom. None of the instructions seem to work. The logic is pretty simple but it is not working.

    Thanks

    How have you connected the EEPROM? A schematic would help.

    Hi,
    I have attached a circuit diagram for your reference. I am using SPI to interface with EPCS4.

    Thanks

    Which "Clock" on the uC are you connecting the EPCS4 to?
