Product details

512 Mbit SPI NOR Flash in a 16-SOIC wide body

The Cypress S25FL512SAGMFIR11 is a 512 Mbit serial NOR Flash memory from the FL-S family, organized as 64M x 8 bits. It communicates over a SPI bus with Quad I/O support, clocked at up to 133 MHz.

At 133 MHz with Quad I/O, this part can sustain read throughput high enough for execute-in-place (XIP) from Flash on many MCUs and SoCs that support Quad-SPI memory-mapped mode. The 512 Mbit density (64 MB) holds a full firmware image plus a fallback or OTA staging partition.

The FL-S family has been a long-running serial NOR series, so PCN risk is low, but always check the latest Cypress/Infineon PCN bulletins before a long production run.

16-SOIC wide — rework-friendly footprint

The leads are gull-wing, so visual inspection of solder joints is straightforward. No exposed pad underneath, so no thermal-via stencil to worry about.

Frequently asked questions

Does S25FL512SAGMFIR11 replace S25FL512SAGMFI10?

The S25FL512SAGMFIR11 and S25FL512SAGMFI10 are both 512 Mbit SPI NOR Flash in the same 16-SOIC package from the FL-S family. The 'R' in the suffix typically indicates a minor revision or process change. Pin-compatibility is expected, but confirm the specific timing and ID parameters against your firmware driver before substituting.

What temperature range does S25FL512SAGMFIR11 support?

This covers most indoor and outdoor equipment that is not under-hood automotive.
