Working Principles

The AT25DF041B-XMHN-B uses the Serial Peripheral Interface (SPI) protocol to communicate with a microcontroller or host device. It stores data in non-volatile memory cells that can be electrically erased and reprogrammed. The SPI interface enables efficient data transfer between the IC and the controlling device.

When data needs to be stored, the microcontroller sends commands and data to the IC through the SPI interface. The IC then writes the data into its memory cells. Similarly, when data needs to be retrieved, the microcontroller sends read commands to the IC, which returns the requested data.
