Working Principles

The 24AA256T-E/MNY 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 stored charge can be later detected during read operations. The I2C interface allows for easy communication between the chip and the controlling device.
