It communicates over a SPI bus with Quad I/O and QPI support, clocking up to 133 MHz — enough to feed a Cortex-M or RISC-V core a boot image or firmware update without stalling the bus. ## Supply and temperature fit The supply range is 1.7 V to 2.0 V, which maps cleanly to a 1.8 V rail — the same rail that powers many MCU I/O banks and DDR memory interfaces. The part draws its operating current from this rail; the peak during a page program or sector erase is higher than the standby figure, so the regulator should be sized for the transient, not the average. ## Package and board integration The datasheet's recommended footprint includes a central ground pad with thermal vias — skipping those vias raises the junction-to-board thermal resistance and limits the write duty cycle before the part throttles. The part is surface-mount and supplied in a Tube. For reflow, the MSL rating should be confirmed from the lot date code; typical WSON packages are MSL-3, meaning a 168-hour floor life after bake before the moisture barrier is exhausted.","metaTitle":"S25FS256SAGNFI001 SPI NOR Flash, 256 Mbit, 133 MHz, 8-WSON","metaDescription":"S25FS256SAGNFI001 256 Mbit SPI NOR Flash from the FS-S series. 133 MHz quad-I/O, 1.7-2V supply, -40 to 85°C.

Quad I/O means it can transfer four bits per clock cycle on the data lines, reaching 133 MHz x 4 = 532 Mbps read throughput. QPI is a separate quad protocol mode that reduces the command overhead by using the same four lines for address and data."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FS256SAGNFI001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FS256SAGNFI001 when reusing this data.
