Product details

256 Mbit Quad-SPI NOR Flash — active, industrial-rated, and ready for new designs

The Cypress (Infineon) S25FL256SAGNFV000 is a 256 Mbit FL-S series NOR Flash memory organized as 32M x 8 bits, accessed through a Quad SPI interface clocked at 133 MHz.

The Quad I/O interface doubles the read throughput over standard SPI by using four data lines simultaneously. At 133 MHz, the effective read rate reaches 66 MB/s in Quad I/O mode, which is sufficient for fast boot, code shadowing, and firmware-over-the-air staging without needing a parallel NOR or a higher-pin-count interface.

This removes the procurement risk of a forced redesign mid-production.

Package and footprint — 8-WSON with exposed pad

The 8-WSON package (6x8 mm) with an exposed pad is a space-efficient footprint for embedded designs. The package is surface-mount, compatible with standard reflow profiles.

Frequently asked questions

Does S25FL256SAGNFV000 support Quad SPI?

Yes, the S25FL256SAGNFV000 uses a Quad I/O SPI interface, which enables four-bit-wide data transfers at up to 133 MHz for higher read throughput compared to standard SPI.

What is the closest functional equivalent to S25FL256SAGNFV000?

The S25FL256SAGMFV000 is a pin-compatible and functionally identical sibling in the same FL-S series, same 256 Mbit density and 133 MHz Quad SPI, but packaged in an 8-SOIC (208 mil) instead of the 8-WSON. The S25FL256SAGMFVG00 is another SOIC variant with the same specs. The S25FL256SAGMFIR00 is a commercial-temperature (85°C) version in SOIC. All share the same die and interface.

Is S25FL256SAGNFV000 RoHS compliant?

Yes, the S25FL256SAGNFV000 is ROHS3 compliant, meeting the latest EU directive requirements without exemptions.
