Quad I/O mode uses four data lines for reads and writes, delivering an effective throughput of 320 Mbps at 80 MHz (four bits per clock). That is enough to feed a Cortex-M4 or M7 core running from external flash without stalling on instruction fetches, provided the controller's QSPI peripheral supports the fast-read command set. The 256 Mbit density (32 MB) gives room for a main application image plus a backup for fail-safe OTA; the FL-S family supports 4 KB and 64 KB sector erase granularity, which matters when sizing the staging area and wear-leveling the config blocks. For the procurement desk, that removes the urgency to stockpile or qualify a drop-in replacement for ongoing production.","metaTitle":"S25FL256SDSMFI003 256Mbit NOR Flash, 80 MHz Quad-SPI","metaDescription":"256Mbit SPI NOR Flash from Cypress FL-S series. 80 MHz Quad I/O, 2.7-3.6V supply, -40°C to 85°C.

The only difference is the packaging medium: the '003 suffix denotes Tape & Reel, while the '001 suffix is typically tube or tray. Both share the same die, same 16-SOIC package, same 80 MHz Quad I/O interface, and same temperature range. A board designed for one will accept the other without any BOM change — just verify the feeder setup on your pick-and-place line for reel vs tube."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL256SDSMFI003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL256SDSMFI003 when reusing this data.
