Working Principles

AT24C02-10PU-1.8 utilizes electrically controlled floating gate transistors to store and retrieve digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. These charges can be removed during the erasing process, allowing new data to be programmed. The memory cells are organized into pages, and data can be accessed using a serial interface.
