Working Principles

The W25Q128FVPIQ operates based on the principles of flash memory technology. It utilizes a floating gate transistor structure to store and retrieve digital information. When data is written, charges are trapped in the floating gate, altering the transistor's behavior. This change in behavior allows the stored data to be retained even when power is removed. The SPI interface facilitates communication between the device and the host system, enabling seamless data transfer.
