The GD25WQ64E is a GigaDevice 64Mbit (8MB) Quad SPI flash memory that supports 1/2/4-line SPI communication with a maximum clock frequency of 104MHz. It operates at a wide voltage range of 1.65V–3.6V and features ultra-low standby power consumption of <1μA. With an industrial temperature range of -40℃ to +85℃, it guarantees 100,000 program/erase cycles and 20-year data retention. The device offers hardware write protection, OTP registers, and program/erase suspend functions, while maintaining compatibility with mainstream SPI Flash drivers. It is widely used in industrial control and smart hardware storage applications.
