Product details

The S25FL256SDSMFI001: The 80 MHz clock rate is the part's top-end SPI clock. In Quad I/O mode, that translates to a sustained read throughput.

The official product status for this order code is listed as Active, but the part also carries an EOL-hot flag in the sourcing channel.

Housed in a 16-SOIC package with a 7.50 mm body width and 0.295 inch lead pitch, the part is a surface-mount device intended for reflow soldering. The 16-SOIC footprint is common across multiple NOR Flash densities in the FL-S family, so a board layout designed for this part can accommodate a density upgrade or a second-source alternate without a PCB change — as long as the alternate shares the same pinout and supply range.

Frequently asked questions

Is S25FL256SDSMFI001 still active or obsolete?

The official product status is listed as Active, but the part carries an EOL-hot flag in sourcing channels. Treat it as a phase-out candidate and plan for a qualified alternate.

What is the replacement for S25FL256SDSMFI001?

No official successor order code is recorded. A pin-compatible alternate from the same FL-S family, such as the S25FL256SAGMFI001, should be qualified before a redesign.

Is S25FL256SDSMFI001 compatible with 3.3V systems?

Yes, the supply range is 2.7 V to 3.6 V, so it works directly on a 3.3 V rail without a level shifter.
