Working Principles

The AT24C64N-10SC utilizes EEPROM technology, which is based on floating-gate transistors. These transistors store charge to represent binary data. When data needs to be written or erased, an electric field is applied to the floating gate, modifying the charge and thus altering the stored data. The I2C interface facilitates communication with the device, allowing for data transfer between the EEPROM and the controlling microcontroller.
