Working Principles

The W25Q128FVCJQ utilizes the SPI interface to communicate with the host device. It stores data in a series of memory cells, which are organized into sectors and blocks. The host device can read or write data by sending commands and addresses through the SPI interface.

During a read operation, the chip receives the address from the host and retrieves the corresponding data from the memory cells. Similarly, during a write operation, the chip accepts the data from the host and stores it in the specified memory location.
