Working Principles

AT24C02-10PI-1.8 utilizes EEPROM technology, which employs floating-gate transistors to store and retrieve data. When a byte is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erase process, allowing the byte to be rewritten.

The I2C interface facilitates communication between the chip and the controlling device. The chip's address pins (A0 and A1) determine its unique address on the bus, enabling multiple chips to coexist in the same system.
