Working Principles

The 24AA025UIDT-I/SN is based on EEPROM technology, which utilizes floating gate transistors to store and retrieve data. When a write operation is performed, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be later sensed during read operations.

The I2C interface allows the IC to communicate with a microcontroller or other devices using a two-wire serial bus. The microcontroller sends commands and data to the EEPROM, which stores the information in its memory cells. During read operations, the stored data is retrieved and sent back to the microcontroller.
