Working Principles

The W25Q256JVBIM TR utilizes the Serial Peripheral Interface (SPI) protocol for communication with the host device. It stores data in non-volatile memory cells, which can be electrically programmed and erased. During read operations, the requested data is retrieved from the memory cells and transferred to the host device via the SPI interface. Similarly, during write operations, data is received from the host device and programmed into the memory cells.
