Working Principles

The AT24C512B-TH25-T utilizes electrically controlled floating gate transistors to store data. When a byte of data needs to be written, an electrical charge is applied to the floating gate, trapping electrons and altering the transistor's behavior. This trapped charge represents the stored data. To read the data, the transistor's behavior is analyzed by applying appropriate voltages. The I2C interface facilitates communication between the chip and the controlling device.
