The 256 Mbit density (organized as 32M x 8) is a sweet spot for a single firmware image plus an OTA staging area in industrial controllers, networking gear, and automotive telematics units. At 133 MHz the SPI clock period is about 7.5 ns. With Quad I/O, four data bits per clock cycle yield an effective throughput of 532 Mbps. That margin matters when the host controller runs at 200 MHz+ and the flash read latency must not stall the instruction prefetch. The part's internal latency and output hold times are spec'd for this clock rate; a slower part at 104 MHz would leave 22% less bandwidth on the table, which shows up as longer boot times or dropped frames in a data-logging pipeline. ## Package and temperature — fit for the board and the environment The 2.7V to 3.6V supply range covers the full 3.3V rail tolerance band, including the low end during a brown-out or cold-crank event. No NRND or last-time-buy notice has been issued for this density-speed-package variant.","metaTitle":"S25FL256SAGMFI001 Cypress FL-S NOR Flash, 256 Mbit, 133 MHz","metaDescription":"Cypress S25FL256SAGMFI001 256 Mbit NOR Flash, SPI Quad I/O, 133 MHz, 2.7V-3.6V, -40°C to +85°C, 16-SOIC.
