Working Principles

The 24AA014-I/SN operates based on the principles of EEPROM technology. It uses a floating gate transistor structure to store and retrieve data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This allows the stored information to be retained even when power is removed. The I2C interface facilitates communication with external devices, enabling data transfer and retrieval.
