Working Principles

The CAT28C64BWI-12T utilizes EEPROM technology, which allows for electrically erasing and reprogramming of data. It stores information in a grid of memory cells that can be individually addressed and modified using specific control signals.

When data needs to be written, the appropriate address is provided along with the data to be stored. The write enable signal (WE) is activated, allowing the data to be programmed into the selected memory cell. Reading data involves providing the desired address and activating the output enable signal (OE), which enables the data to be read from the specified memory location.
