Working Principles

The 24LC014T-I/OT utilizes electrically erasable programmable read-only memory (EEPROM) technology. It consists of a grid of memory cells, each capable of storing a single bit of data. These cells can be individually programmed or erased using electrical signals.

During write operations, the chip applies a high voltage to the selected memory cell, causing it to store a logical 1 or 0. Erasing is achieved by applying an electrical charge that resets the cell to its initial state.

The I2C interface allows communication between the 24LC014T-I/OT and other devices, enabling data transfer and manipulation.
