Working Principles

The 93LC46A-I/PG is based on EEPROM technology, which utilizes floating gate transistors to store and retrieve data. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasing process, allowing new data to be written. The IC uses a serial interface to communicate with the host device, enabling efficient data transfer.
