Working Principles

W25Q16VSSIG utilizes the Serial Peripheral Interface (SPI) to communicate with the host device. It follows a master-slave architecture, where the host device acts as the master and the memory chip as the slave. The host initiates data transfer by sending commands and addresses to the memory chip, which responds with the requested data.

The memory is organized into sectors and pages, allowing for efficient read, write, and erase operations. Data can be written to individual pages or erased at the sector level. The status register provides information about the memory's operational status and configuration.
