Working Principles

The W25X80VDAIZ is based on the Serial Peripheral Interface (SPI) protocol, which allows for high-speed data transfer between the memory and a microcontroller or host device. It utilizes non-volatile memory technology, specifically Flash memory, which enables data to be stored even when power is removed.

The memory can be accessed by sending commands through the SPI interface, allowing for read, write, erase, and other operations. The data is organized into sectors, which can be individually erased or programmed with new information.
