Working Principles

The AT24C512W-10SU-2.7 utilizes EEPROM technology, which employs a floating-gate transistor structure to store and retrieve data. When data needs to be written, an electric charge is applied to the floating gate, altering its electrical characteristics. This change in charge determines the stored data value. Reading the data involves measuring the electrical properties of the floating gate to determine the stored charge level.
