Working Principles

The CAT24C32HU4I-GT3 utilizes EEPROM technology, which employs floating-gate transistors to store and retrieve digital information. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be retained for an extended period, allowing the stored data to persist even when power is removed. During read operations, the stored charge is sensed, and the corresponding data is retrieved.
