Working Principles

The AT24C64N-10SI-2.5 utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It uses a serial interface (I2C) to communicate with the controlling microcontroller or system. The data is stored in non-volatile memory cells that retain their state even when power is removed.

During operation, the microcontroller sends commands and addresses to the AT24C64N-10SI-2.5 via the SDA and SCL lines. The IC responds by reading or writing data from/to the specified memory location. The WP pin can be used to enable or disable write protection, preventing accidental modification of stored data.
