Working Principles

The 25LC512T-I/MF uses a floating-gate transistor structure to store data. When data is written, an electric charge is trapped in the floating gate, altering the transistor's behavior. This charge remains even when power is removed, allowing the chip to retain the stored information. The SPI interface facilitates communication between the chip and the microcontroller, enabling read and write operations.
