Working Principles

The AT25640N-10SI utilizes EEPROM technology to store data. It employs a floating gate transistor structure that can be electrically programmed and erased. 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 the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the SPI interface.
