Product details

128 Mbit NOR Flash with Quad-SPI at 108 MHz

It uses an SPI bus with Quad I/O support, clocked at 108 MHz.

Supply and temperature — where it fits the board

Operating supply is 2.7V to 3.6V, which aligns with standard 3.3V logic rails.

There is no last-time-buy clock running, so it remains design-in viable for new BOMs. If you are dual-sourcing, the FL-S family includes density and package variants that share the same Quad-SPI command set, but no official second-source alternate is recorded for this exact order code.

Frequently asked questions

Is S25FL127SABNFI101 compatible with SPI?

Yes, it uses an SPI interface with Quad I/O support. It is backward-compatible with standard single-bit SPI and also supports dual and quad reads for higher throughput.
