Working Principles

The AT24C32AN-10SI-1.8 utilizes electrically controlled floating gate transistors to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erase process, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the I2C interface.
