Working Principles

The FT24C04A-UTG-T utilizes electrically erasable programmable read-only memory technology. It consists of a grid of memory cells that can be individually programmed or erased by applying appropriate electrical signals. Data is stored in these cells as binary information (0s and 1s) by altering the electrical charge on specific memory cells.

During read operations, the chip retrieves the stored data by sensing the electrical state of each memory cell. Write operations involve applying specific voltage levels to program or erase the desired memory cells.
