Product details

It comes in an 8-WSON package with an exposed pad (6x8 mm body) for thermal relief.

If you need a drop-in replacement for new designs, the S25FL128S series (same package, same Quad-SPI interface) is the official successor; verify pin compatibility against your layout before committing the BOM.

104 MHz Quad-SPI — read throughput and timing margin

That is enough to feed a Cortex-M or a small FPGA without a separate parallel NOR. The 3 ms page program time is the bottleneck if you are logging data; for code storage it is irrelevant.

Package and footprint — 8-WSON with exposed pad

This pad is not just for heat — it also provides a low-inductance ground return for the SPI signals.

Frequently asked questions

Where can I buy S25FL129P0XNFV000?

The S25FL129P0XNFV000 is obsolete and no longer in factory production.

Is S25FL129P0XNFV000 obsolete?

Yes, the S25FL129P0XNFV000 carries an obsolete lifecycle status. It is no longer manufactured by Cypress/Infineon. For new designs or volume production, the S25FL128S series is the recommended replacement — verify pin compatibility before switching.

What is the replacement for S25FL129P0XNFV000?

The official successor is the S25FL128S series, which shares the same package (8-WSON) and Quad-SPI interface. The S25FL128S offers higher performance and continued availability. Check the pinout and register map against your design before substituting.

What is the memory size of S25FL129P0XNFV000?

The S25FL129P0XNFV000 is a 128 Mbit NOR Flash, organized as 16M x 8 bits.
