Working Principles

The 24AA04/P EEPROM utilizes a floating gate transistor structure to store digital information. When writing data, an electric charge is applied to the floating gate, altering its electrical characteristics. This change can be detected during read operations, allowing the retrieval of stored information. The I2C protocol facilitates communication between the IC and the controlling microcontroller.
