Working Principles

The AT24C08C-SSHM-B utilizes EEPROM technology, which employs 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 erasure, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the I2C interface.
