Product details

The S25FL128SAGNFV003: SPI Quad I/O interface at 133 MHz, 128Mbit organized as 16M x 8.

Quad I/O at 133 MHz reads at the bus rate supported by the controller.

Infineon lists the S25FL128SAGNFV003 as Active. For a production BOM that needs a stable NOR Flash through a multi-year product run, this part carries no forced-migration risk today.

Package and mounting — 8-WSON with exposed pad

The exposed pad should be soldered to a PCB thermal land and connected to ground for heat sinking — the datasheet's recommended footprint is the reference to follow.

Frequently asked questions

Does S25FL128SAGNFV003 support Quad SPI?

Yes, the memory interface is SPI Quad I/O. It supports single, dual, and quad I/O commands, including fast-read quad-output at 133 MHz. The part is compatible with standard Quad SPI controllers on MCUs and SoCs.

What are alternatives to S25FL128SAGNFV003?

Pin-compatible alternatives in the same 8-WSON footprint include the Winbond W25Q128JV and Macronix MX25L12835F. Both are 128 Mbit NOR Flash with Quad SPI and similar supply and temperature ranges. The choice between them often comes down to supply-chain dual-sourcing strategy rather than a functional difference.
