Working Principles

AT94S40AL-25BQI operates based on the principles of serial data transfer using the SPI interface. It receives data from the master device through the MOSI pin, processes it internally, and transmits the processed data back to the master device through the MISO pin. The clock signal provided through the SCK pin synchronizes the data transfer between the master and the IC. The CS pin is used to select the IC for communication.
