Working Principles

The X24C44SI is a non-volatile memory IC that utilizes EEPROM technology. It stores data in an electrically erasable and programmable memory array. The device communicates with the microcontroller or host system through the I2C interface. It supports both read and write operations, allowing byte-wise random access to the memory.

During a write operation, the X24C44SI automatically erases the targeted memory location before writing new data. The self-timed write cycle ensures data integrity and prevents corruption. The device also offers software and hardware write protection mechanisms to prevent accidental modifications.
