Working Principles

The 24LC64T-I/MC utilizes electrically erasable programmable read-only memory (EEPROM) technology. It stores data by trapping electric charges within a floating gate structure. To write data, an electrical charge is applied to the floating gate, altering its state. Reading data involves detecting the presence or absence of a charge in specific memory cells. The I2C interface facilitates communication between the chip and the controlling device.
