Product details

This is not a last-time-buy window; it means production has ceased and the part is no longer available through authorized factory channels. Sourcing now runs through independent distribution, where we can locate new-old-stock or surplus inventory against an RFQ.

128Mbit SPI Quad I/O NOR Flash — key specs for design fit

This is a 128Mbit (16M x 8) SPI Quad I/O NOR Flash memory from Infineon's FL-S series.

Rated for 2.7V to 3.6V supply, the S25FL127SABNFV101 operates directly on a 3.3V rail. The SPI and Quad I/O inputs are 3.3V-tolerant, so it interfaces cleanly with most 3.3V MCUs and SoCs without external level translation. If the host runs at 1.8V I/O, a voltage translator on the SPI lines is needed.

Supplied in an 8-WDFN with exposed pad, the supplier device package is 8-WSON (5x6).

Frequently asked questions

Where can I buy S25FL127SABNFV101 and get a price?

Submit an RFQ through this listing for a real-time sourcing check.

What is the replacement for S25FL127SABNFV101?

The lifecycle record does not list an official replacement order code. A pin-compatible alternative may exist within the same FL-S family or from other NOR Flash vendors, but that requires validation against your specific application — footprint, supply voltage, and interface timing.

Is S25FL127SABNFV101 compatible with 3.3V logic?

Yes. The supply voltage range is 2.7V to 3.6V, and the SPI interface operates at 3.3V logic levels without additional translation.
