Working Principles

The 24LC128T-I/MS utilizes EEPROM technology, which allows for non-volatile data storage. It employs an array of floating-gate transistors that can be electrically programmed and erased. When data is written, charges are trapped in the floating gates, representing the stored information. These charges can be later read or erased as needed.

The chip communicates with the host microcontroller or device using the I2C protocol. The SDA and SCL lines are used for bidirectional data transfer, allowing the microcontroller to read from or write to specific memory locations.
