Product details

108 MHz quad-SPI — the throughput number that matters

The S25FL064LABNFN040 is a 64 Mbit NOR flash from Infineon's FL-L series, built for code-shadowing, data logging, and OTA staging in industrial and automotive-temperature designs. Its 108 MHz SPI clock, combined with Quad I/O and QPI interfaces, delivers read throughput that keeps an MCU's execute-in-place (XIP) path fed without wait-state bottlenecks.

Active lifecycle — no forced redesign on the horizon

Infineon lists this part as Active. No last-time-buy notices, no NRND flags.

The memory interface supports both SPI Quad I/O and QPI. In Quad I/O mode, the 108 MHz clock yields read throughput for a 64 Mbit firmware image.

Frequently asked questions

Is S25FL064LABNFN040 end of life or active?

Active. Infineon's product status lists it as current-production with no end-of-life notice. No forced redesign or last-time-buy window to track.

What is the difference between S25FL064LABNFN040 and S25FL064LABNFI040?

The difference is the temperature grade. Both share the same 64 Mbit density, 108 MHz SPI, and 8-USON package.

Is S25FL064LABNFN040 directly compatible with 3.3V SPI?

Yes. No level translator needed when connecting to a 3.3 V MCU or SoC.
