Working Principles

M25PE80-VMN6P utilizes the Serial Peripheral Interface (SPI) protocol for communication. It stores data in non-volatile memory cells, which retain information even when power is disconnected. The microcontroller communicates with the flash memory chip using the SPI interface, enabling read and write operations.

During a read operation, the microcontroller sends a command along with the memory address to be accessed. The flash memory responds by transmitting the requested data back to the microcontroller.

For write operations, the microcontroller sends a command along with the data to be written and the memory address. The flash memory then stores the data at the specified address.
