Working Principles

The 93LC56A-I/P is based on EEPROM technology, which utilizes floating gate transistors to store and retrieve digital information. When data needs to be written, a high voltage is applied to the gate of the selected transistor, trapping electrons in the floating gate. This alters the threshold voltage of the transistor, representing a logical "1" or "0". To erase the data, a higher voltage is applied to remove the trapped electrons.

During normal operation, the chip select (CS) pin is activated to enable communication with the device. The clock input (CLK) synchronizes the data transfer, while the data input (DI) and data output (DO) pins handle the actual data exchange. The write protect (WP) pin can be used to prevent accidental modification of the stored data.
