The 2.7V to 3.6V supply range matches 3.3V logic families directly, so no level shifters are needed on the SPI bus. For production builds with multi-year horizon, this means no imminent last-time-buy or end-of-life notice. ## Industrial temperature grade and 16-SOIC footprint At 133 MHz, the Quad I/O interface delivers a theoretical peak read rate of 532 Mbps (four data lines × 133 MHz). For real-world firmware reads, the controller must support Quad I/O commands (1-4-4 or 4-4-4 protocol). The 256 Mbit density provides 32 MB of non-volatile storage, enough for a full application image plus a fallback recovery partition in many embedded designs. The 2.7V minimum supply ensures operation through the lower end of a 3.3V rail with typical ±5% tolerance.","metaTitle":"S25FL256SAGMFIG01 256Mbit NOR Flash, 133 MHz SPI Quad I/O","metaDescription":"Cypress S25FL256SAGMFIG01 256Mbit SPI NOR Flash, 133 MHz clock, Quad I/O, 2.7V-3.6V, -40°C to 85°C, 16-SOIC.
