Product details

256 Mbit SPI NOR Flash — the part that keeps the firmware alive

The Infineon S25FL256LAGNFV011 is a 256 Mbit SPI NOR Flash from the FL-L series, built for code-shadowing, parameter storage, and OTA staging in industrial and automotive-adjacent designs. It talks over SPI with Quad I/O and QPI support at up to 133 MHz, giving a sustained read throughput that keeps a Cortex-M7 fed without wait states. The 32M x 8 organization maps neatly to a linear address space for execute-in-place boot loaders.

At 133 MHz in Quad I/O mode, the part delivers roughly 66 MB/s read bandwidth — enough to stream a 256 Mbit image in under half a second. That matters when the OTA staging area sits on this Flash and the MCU needs to validate and copy the update without stalling the application.

Industrial temperature grade — deployment envelope

Surface-mount assembly is straightforward with standard reflow profiles — MSL level is typical for this class, but check the moisture-sensitive label before bake decisions.

Lifecycle and sourcing posture

For BOM planning, the base product number S25FL256 covers multiple package and temperature variants, making it straightforward to qualify a second footprint if the 8-WSON becomes tight.

Frequently asked questions

Can S25FL256LAGNFV011 replace S25FL256L?

The S25FL256LAGNFV011 is itself a member of the FL-L series, so it is a direct replacement for other S25FL256L variants in the same package and temperature grade. For a different package or temperature range, verify the specific variant's footprint and ratings.

What is the closest functional equivalent to S25FL256LAGNFV011?

The S25FL256SAGMFV001 from the FL-S series is a close functional peer — same 256 Mbit density, same 133 MHz SPI clock, same 2.7 V supply, and same 32M x 8 organization. The key difference is the interface: the FL-L part adds QPI mode, while the FL-S part supports only Quad I/O. Check whether your SPI controller handles QPI before substituting.
