Working Principles

The AT24C02AN-10SC-2.5 is based on EEPROM technology. It utilizes floating-gate transistors to store and retrieve digital information. When data needs to be written, an electric charge is applied to the floating gate, altering its electrical characteristics. This change is then detected during read operations, allowing the stored data to be retrieved.
