Product details

128 Mbit NOR Flash for firmware storage and code shadowing

The SPI Quad I/O interface at 80 MHz delivers a sustained read throughput of 320 Mbps — enough to shadow a boot image into RAM without stalling the host processor.

Housed in a 16-SOIC package (0.295-inch body width, 7.50 mm), the S25FL128SDSMFB001 uses the standard JEDEC SOIC-16 wide footprint. The 1.27 mm pin pitch is hand-solderable and rework-friendly — no hot-air nozzle alignment needed for a rework station.

Active lifecycle — no end-of-life clock running

Infineon lists this part as Active. No LTB notice, no successor announced.

Frequently asked questions

Can S25FL128SDSMFB001 replace S25FL128SDSMFI001?

The S25FL128SDSMFI001 is the same 128 Mbit FL-S die in an industrial-temperature grade. The suffix difference (B001 vs I001) typically indicates packaging or marking variant — confirm the BOM position's package code and temperature grade before substituting. Both are active, same density and interface.

What package does S25FL128SDSMFB001 come in?

16-SOIC wide body (0.295-inch, 7.50 mm width) — supplier device package is 16-SOIC.

Does S25FL128SDSMFB001 support Quad I/O SPI?

Yes — the memory interface is SPI - Quad I/O. The four data lines plus clock and chip select deliver 320 Mbps read throughput at the 80 MHz clock rate.
