Working Principles

The 25LC080BT-I/MSG utilizes the Serial Peripheral Interface (SPI) protocol for communication with the microcontroller. It stores data in an array of memory cells that can be electrically erased and reprogrammed. When data needs to be written, the microcontroller sends the address and data to the device using SPI commands. The device then stores the data in the specified memory location. During read operations, the microcontroller sends the address, and the device retrieves the corresponding data from the memory array.
