Working Principles

The X1286A8 is based on EEPROM technology, which allows for electrically erasing and reprogramming data. It utilizes a floating gate transistor structure to store charge, representing binary information. The IC communicates with the host device through the I2C interface, enabling read and write operations. When data is written, the charge is trapped in the floating gate, ensuring data retention even without power.
