Working Principles

The CAT24C02TDI-GT3 utilizes a combination of floating-gate transistors and control circuitry to store and retrieve data. When data is written, an electrical charge is trapped in the floating gate, altering the transistor's behavior. This charge can be removed during the erasing process, allowing new data to be programmed. The chip's internal control circuitry manages the read, write, and erase operations, ensuring reliable data storage and retrieval.
