Working Principles

The X40431V14-B 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 microcontroller through the I2C interface, enabling read and write operations. During write cycles, the data is programmed by applying voltage pulses to the memory cells. The stored information remains intact even when power is removed.
