That is enough to feed a Cortex-M or RISC-V core running from external Flash without stalling on instruction fetches, provided the controller's SPI peripheral can keep up. The 256 Mbit density holds a full firmware image plus a config file or calibration table, with room for a backup slot if you double the footprint. For designs that shadow code into RAM at boot, the 66 MHz clock keeps the copy time under a couple hundred milliseconds. The FL-S series has a broad density range (from 64 Mbit up to 1 Gbit), so a future migration to a larger or smaller part within the same family keeps the same package and interface — useful if the firmware grows or the BOM needs cost reduction. ## 16-SOIC footprint — layout notes The 16-SOIC package (0.295 inch body width, 7.50 mm) is a common NOR Flash footprint shared across the FL-S family and many competitors.","metaTitle":"S25FL256SDPMFIG01 256Mbit NOR Flash, 66 MHz SPI Quad I/O","metaDescription":"S25FL256SDPMFIG01 is a 256Mbit SPI NOR Flash from the FL-S series. 66 MHz Quad I/O interface, 2.7V–3.6V supply, -40°C to 85°C.
