Working Principles

W25Q16DWSSIG TR operates based on the principles of flash memory technology. It uses floating-gate transistors to store data in an array of memory cells. The data is stored by trapping electric charges in the floating gate, which can be later erased or programmed using electrical signals.

The Serial Peripheral Interface (SPI) allows the host device to communicate with the flash memory by sending commands and data through the DI (Data Input) and DO (Data Output) pins. The CLK (Clock) pin synchronizes the data transfer between the host and the memory device.
