Working Principles

The W25Q20EWZPIG TR operates based on the Serial Peripheral Interface (SPI) protocol. It uses a combination of clock signals, data input/output lines, and control signals to communicate with the host device. The flash memory is organized into sectors and blocks, allowing for efficient data storage and retrieval. The memory cells store data in a non-volatile manner, ensuring that the stored information remains intact even when power is removed.
