Working Principles

The 24AA512T-I/SM utilizes EEPROM technology, which employs floating gate transistors to store and retrieve data. When data is written, an electric 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 I2C interface facilitates communication between the host device and the EEPROM chip, enabling data transfer and control operations.
