Product details

128 Mbit NOR Flash with AEC-Q100 qualification — the grade the auditor expects

The S25FL128SDSMFBG10: AEC-Q100 qualification covers the reliability tests automotive OEMs require for PPAP submission.

80 MHz Quad-SPI — throughput for code-shadowing and fast OTA

The SPI Quad I/O interface running at 80 MHz gives a practical read throughput that makes this part suitable for execute-in-place code shadowing or high-speed firmware update staging. In a typical automotive ECU boot sequence, the MCU reads the application image from this Flash at quad rates, cutting the wake-up time compared to a single-bit SPI part.

16M x 8 organization and 16-SOIC footprint

Organized as 16M x 8, the 128 Mbit density maps directly to byte-addressable file systems used in automotive data logging and parameter storage. The surface-mount package suits automated pick-and-place.

Active status — no LTB pressure for new designs

For a BOM line going into a new automotive program with a five-to-seven-year production run, this removes the sourcing risk of a forced redesign mid-cycle.

Frequently asked questions

Is S25FL128SDSMFBG10 available via RFQ confirmation?

Stock levels change daily across the independent distribution channel. The quickest way to get a current stock picture and lead time is to submit an RFQ for your target quantity — we confirm availability at quote time.

Can S25FL128SDSMFBG10 replace S25FL128SAGMFBG10?

Both parts share the same 128 Mbit density, SPI Quad I/O interface, and 16-SOIC package. The S25FL128SDSMFBG10 is from the Automotive FL-S series with AEC-Q100 qualification, while the SAG variant targets the industrial grade. Verify pin compatibility and the exact qualification level against your BOM requirements before substituting.

Is S25FL128SDSMFBG10 RoHS compliant?

The manufacturer lists this part in a RoHS-compliant series. Confirm the specific date code and lot compliance certificate with your supplier at order time, as is standard practice for automotive-grade components.
