Working Principles

The AT24C16D-MAHM-T utilizes a floating-gate transistor structure to store data. When programming, an electric charge is trapped in the floating gate, representing a logical "1" state. Erasing the data involves removing this charge, returning the cell to a logical "0" state. The chip's internal circuitry handles the read, write, and erase operations based on the input signals received through the I2C interface.
