Working Principles

The X4043M8-2.7A is a non-volatile memory control and protection IC that utilizes a serial interface for data transfer. It operates by receiving commands and data through the serial input (SI) pin, which are then processed and stored in its internal memory array. The chip select (CS) pin enables or disables the IC for communication. The write protect (WP) pin can be used to prevent accidental modification of stored data. The IC can be powered by a supply voltage ranging from 2.7V to 5.5V.
