Working Principles

The W25Q32DWSSIG utilizes the Serial Peripheral Interface (SPI) to communicate with the host device. It stores digital information in non-volatile memory cells, which retain data even when power is disconnected. The SPI interface enables high-speed data transfer between the device and the host, allowing for efficient read and write operations.
