Working Principles

AT24C01C-XHM-B utilizes EEPROM technology to store digital information. It consists of an array of memory cells that can be individually addressed for read or write operations. The chip communicates with the host device using the I2C protocol, which allows for easy integration into various systems. When data is written, it is stored in the memory cells using electrically controlled charge trapping mechanisms. During read operations, the stored charges are sensed and converted back into digital data.
