The GD25Q64C is GigaDevice's 64Mb (8MB) NOR Flash chip — a pin-compatible, cost-effective alternative to the Winbond W25Q64JV. It operates at up to 120MHz with SPI, Dual I/O, and Quad I/O modes, providing the same interface as the W25Q64 with competitive pricing for high-volume production.
In drone applications, GD25Q64C is used as a blackbox flash storage chip on FC boards, providing 8MB of flight data logging capacity — equivalent to approximately 80 minutes of Betaflight high-rate logging. Many FC manufacturers use GD25Q chips as volume alternatives to Winbond on their production boards.
