Working Principles

The SST25VF080B-80-4C-S2AE-T operates based on the Serial Peripheral Interface (SPI) protocol. It uses a combination of clock signals and serial data transfer to communicate with the host microcontroller or system. The device stores data in non-volatile memory cells, which can be electrically programmed and erased.

When data needs to be read, the microcontroller sends appropriate commands and addresses to the flash memory. The flash memory responds by sending the requested data back to the microcontroller via the SPI interface. Similarly, when data needs to be written, the microcontroller sends the data along with the necessary commands and addresses to the flash memory, which then stores the data in the specified memory locations.
