That translates to roughly 66 MB/s raw throughput, which keeps the CPU fed during code fetch without wait states on most Cortex-M and RISC-V cores. The QPI mode cuts the command overhead on random reads by using a single 4-bit bus for both address and data, improving efficiency on scattered accesses like interrupt vectors. ## 125°C rating — where it runs without a fan No derating needed for self-heating in a sealed enclosure; the NOR Flash draws low enough active current that junction temp stays close to ambient. ## 16-SOIC wide-body — rework-friendly footprint The 16-SOIC (0.295\", 7.50 mm width) package is a gull-wing leaded form that is straightforward to hand-solder and inspect. Unlike QFN or BGA, you can probe the pins, rework it with hot air without lifting pads, and visually verify solder joints. The wide body also helps with thermal dissipation if the part is running near the 125°C limit.","metaTitle":"S25FL256LAGMFN001 256Mbit NOR Flash, SPI Quad I/O, 133 MHz","metaDescription":"Cypress S25FL256LAGMFN001 256Mbit NOR Flash memory.
