It communicates over a Quad SPI interface at up to 133 MHz, giving the host controller a fast read path for code shadowing or execute-in-place firmware.
The ROHS3 compliance is current – no exemption expiry to track.
16-SOIC wide body – rework-friendly footprint
Pin pitch is 1.27 mm, which means you can probe signals, hand-rework with hot air, and inspect joints under a microscope without X-ray. No hidden balls, no underfill. The tube shipping medium is fine for low-volume builds, but if your pick-and-place line feeds from tape, note that the sibling S25FL256SAGMFIR00 ships in a tray – check the reel option if you need high-volume automated assembly.
Quad SPI at 133 MHz – bus margin matters
That's enough to feed a Cortex-M7 or a mid-range FPGA configuration controller without stalling. The interface supports Quad I/O commands, so the four data lines are bidirectional – check your host's QSPI controller supports the command set (the FL-S series uses the standard JEDEC SPI NOR command set, not a proprietary extension).
