The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. *25XX040 is used in this document as a generic part number for the 25AA040/25LC040/25C040 devices. Communication to th...
