    How cab be drive a system with below requirement -

    1. Lets say a microcontroller is driven by 5Vor 3.3V VDC.
    2. And a EEPROM suppose to be driven by 1.8V.

    Lets say i need to interface a microcontroller to EEPROM by using I2C protocol.

    So how can be driven ???

    This is an easy one. You get a device that is made for that purpose.

    You may have to search a bit harder for one that operates at 1.8V
