Working Principles

The W25Q32FVZPJF utilizes the Serial Peripheral Interface (SPI) protocol for communication with the host device. It stores data in non-volatile memory cells, which retain information even when power is turned off. The chip uses a combination of floating-gate transistors and charge storage techniques to store and retrieve data.

During read operations, the host device sends commands and addresses to the chip via the SPI interface. The chip then retrieves the requested data from the memory cells and transmits it back to the host device. Write operations involve sending data to be stored in specific memory locations.
