Working Principles

The AT24C32N-10SI utilizes electrically controlled floating gate transistors to store and retrieve data. When data is written, an electrical charge is applied to the floating gate, altering its conductivity. This charge can be removed during the erase operation, allowing the transistor to return to its original state. The stored data can be accessed by sending appropriate commands through the I2C interface.
