Working Principles

The AT24C02A-10TU-2.7 chip utilizes EEPROM technology, which employs a grid of floating-gate transistors to store data. When a byte is written, an electric charge is trapped in the floating gate, representing a logical "1" or "0". The stored data can be read by applying appropriate voltage levels to the memory cells. Erasing the data involves removing the trapped charges using electrical pulses.
