Product details

Active lifecycle — no LTB risk

There is no last-time-buy notice, no NRND flag, and no announced EOL. You can commit this part to a production BOM without worrying about an imminent phase-out. The FL-S series is a mature, widely used NOR Flash family with multiple density and temperature variants, so supply depth is good across the channel.

For volume production or urgent BOM fills, submit an RFQ — we will return a firm price and lead time based on real-time channel inventory. The active lifecycle means you are not chasing surplus stock; the part is still flowing through normal supply lines.

Frequently asked questions

What is the equivalent of S25FL128SDSNFI000?

The closest functional equivalent within the same FL-S family is the S25FL128SAGMFV010, which runs at 133 MHz and supports a -40°C to 105°C temperature range. The S25FL128SAGBHIA10 is a 133 MHz, -40°C to 85°C variant in a BGA package. Both are pin-compatible for Quad I/O SPI but differ in speed grade and temperature range.

Is S25FL128SDSNFI000 compatible with 3.3V systems?

Yes, the supply voltage range is 2.7 V to 3.6 V, which directly covers 3.3 V logic rails. No level shifting is needed for the SPI bus if the host controller also runs at 3.3 V.
