The 133 MHz Quad-SPI read throughput keeps boot times under a few hundred milliseconds on a typical Cortex-R or Cortex-M core. The AEC-Q100 qualification is the gate for any automotive ECU, ADAS module, or telematics unit. Without it, a NOR Flash on the BOM triggers a PPAP deviation — this part clears that line item. The 125°C operating temperature covers under-hood soak-back and engine-bay heat, not just the cabin's 85°C max. No external regulator needed if the MCU's VDDIO is 3.3 V — the Flash tracks the same rail. For a production BOM line that will run for another three to five years, this part does not force a qualification requal or a second-source search — yet. ## 16-SOIC package — footprint and rework The 16-SOIC package (0.295\", 7.50 mm width) is a surface-mount wide-body SOIC — the same footprint used across the FL-S family's 256 Mbit and 512 Mbit density options. The supplier device package is 16-SOIC. On the rework bench, the wide-body SOIC is easier to hot-air remove than a QFN or BGA; the scorch mark on a failed part is usually on pin 1 side if a supply overvoltage took out the I/O ring.","metaTitle":"S25FL256SAGMFM000 256Mbit NOR Flash, AEC-Q100","metaDescription":"Cypress S25FL256SAGMFM000 256Mbit NOR Flash, AEC-Q100 qualified, -40°C to 125°C, 133 MHz Quad-SPI, 16-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100, FL-S","Package":"Tray","Technology":"FLASH - NOR","Memory Size":"256Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL256","Memory Organization":"32M x 8","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL256SAGMFM000 automotive AEC-Q100 qualified?","answer":"Yes, the S25FL256SAGMFM000 is listed under the Automotive, AEC-Q100 series."},{"question":"Can S25FL256SAGMFM000 be used as a drop-in replacement for S25FL256SAGMFI000?","answer":"The S25FL256SAGMFM000 and S25FL256SAGMFI000 share the same 256 Mbit density, Quad-SPI interface, and 16-SOIC package. The key difference is the temperature grade: the FM000 variant is rated -40°C to 125°C versus the FI000's industrial range. If your board is specified for the full automotive temperature range, the FM000 is the correct fit. For commercial or industrial environments, the FI000 may suffice — but verify the operating temperature requirements of your specific application before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL256SAGMFM000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL256SAGMFM000 when reusing this data.
