Working Principles

The AT24C32A-10PU-1.8 utilizes EEPROM technology, which relies on 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 erasing process, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the I2C interface.
