GD25Q32CSIG – Serial NOR Flash – GigaDevice

The GigaDevice GD25Q32CSIG is a 32 Mbit (4M x 8) serial NOR Flash memory with a Standard/Dual/Quad SPI interface, 120 MHz fast read, and a 2.7V-3.6V supply, supplied in an 8-pin SOP (208 mil) package.

The GD25Q32CSIG from GigaDevice is a 32 Mbit (4M x 8) Serial NOR Flash memory device from the GD25Q “3.3V Uniform Sector” family. It connects to a host over a Serial Peripheral Interface (SPI) and supports Standard, Dual, and Quad I/O operation, delivering fast read performance up to 120 MHz (with a 30 pF load). The device is organized in 4 KB uniform sectors and 32 KB/64 KB uniform blocks, and is housed in an industry-standard 8-pin SOP (208 mil) package, making it a common boot/code-storage and data-storage Flash for embedded systems.
