Compatibility & sourcing notes
Standard SPI NOR operations (03h/0Bh read, 20h 4KB erase, 02h page-program, 9Fh JEDEC ID) and the SOIC-8 footprint are compatible. But the legacy SST25VF uses the proprietary AAI word-program (ADh) that GD25Q does not support — such firmware must switch to standard page-program; the SST26VF is a modern SFDP/SQI part with a different block-protection model. The JEDEC ID also differs (GD 0xC8). Re-validate the driver — a design-in alternative.
A functional alternative requiring design-in: pinout and driver may differ — re-validate with the corresponding development resources before production.
