Product details

It communicates over a SPI bus with Quad I/O support, clocked at up to 133 MHz. That clock rate, combined with the quad data lines, gives a theoretical read throughput of 532 Mbps — enough to support execute-in-place (XIP) for many MCUs without a separate DRAM cache. The supply range is 2.7V to 3.6V, which aligns with common 3.3V logic rails.

Industrial temperature range — fits most embedded and telecom environments

If your design needs the extended -40°C to 105°C range, the sibling S25FL128SAGMFV010 or S25FL128SAGMFB000 carry that rating in the same 16-SOIC footprint.

Package and reflow — 16-SOIC wide body, MSL check before the oven

Housed in a 16-SOIC with 0.295-inch body width (7.50 mm), this is a standard surface-mount package. The tray shipping medium is fine for volume assembly.

Active lifecycle — no EOL risk for new designs

Frequently asked questions

Does S25FL128SAGMFI000 support quad SPI interface?

Yes. The memory interface is SPI with Quad I/O (four data lines), allowing read speeds up to 532 Mbps at the 133 MHz clock. That's the standard Quad SPI mode used by most modern MCUs and SoCs for fast firmware loading or XIP.
