The GD25Q64CFIGR is a 64Mb (8Mb x 8) serial flash memory device manufactured by Gigadevice. It has an operating temperature range of -40°C to +85°C and is available in an 8-pin SOIC package. Its advanced design includes a single-supply voltage of 1.8V for read and write operations, as well as a four I/O pin-configurable design, which allows for flexibility, compatibility, and ease of design. The GD25Q64CFIGR has the advanced feature of dual output enable pins, allowing two independent chip enable signals for read and write operations. With a fast maximum clock frequency of 50MHz, the GD25Q64CFIGR supports a variety of serial protocol interfaces, including SPI, 2-bit, 2-bit protocol, 8/16-bit Multiple-I/O, Dual-SPI, Dual-I/O and Quad-SPI. It also features an Erase Suspend/Resume extension that enables applications to secure data in an area while erasing other areas of the device.
