Working Principles

The AT24C32A-10TI-1.8 utilizes EEPROM technology, which relies on the trapping and releasing of electric charges in a floating gate structure. When data is written, an electric charge is trapped in the floating gate, representing a logical state. To erase the data, the charge is removed from the floating gate. The stored data can be read by sensing the presence or absence of charge in the floating gate.
