Compatibility & sourcing notes
Adesto/Renesas AT25SF (e.g. AT25SF081/161B/321B) is standard JEDEC 25-series 3V SPI NOR (2.5/2.7~3.6V, SPI mode 0/3, 9Fh JEDEC ID, Dual/Quad) in SOIC-8, pin- and command-compatible with GD25Q on the same footprint. Caveat: update firmware that compares the JEDEC manufacturer ID (Adesto/Renesas 0x1F vs GigaDevice 0xC8) and confirm matching density/features.
The two share a footprint and interface and can usually be swapped directly; before mass production, still confirm voltage, density, and timing against both datasheets.
