128 Mbit NOR Flash for code shadowing and data logging
The Cypress S25FL128SAGMFB013 is a 128 Mbit NOR Flash from the FL-S series, built for execute-in-place (XIP) code storage, firmware shadowing, and data logging in industrial and telecom gear. It talks SPI with Quad I/O at 133 MHz, which gives a solid read throughput for booting a processor or streaming OTA updates.
At 133 MHz the SPI clock period is about 7.5 ns. With Quad I/O the effective read throughput hits roughly 66 MB/s in fast-read mode. That is enough to feed a Cortex-M7 or a mid-range FPGA configuration controller without stalling.
Temperature grade and field deployment
The 105°C ceiling covers most under-hood and high-ambient industrial slots without needing a ceramic or hermetic package. Storage temperature exceeds the operating range — the part can sit in a hot warehouse or an unheated truck without damage.
16-SOIC with 7.50 mm body width and 1.27 mm pitch. The wide pitch makes it solderable with a standard iron and inspectable under a loupe — no hot-air station required for a field swap. The tape-and-reel option (Cut Tape also available) suits both prototyping and production pick-and-place.
For a production line that needs a second source, the S25FL128SAGMFI013 is a sibling in the same family (same die, same footprint, same speed grade) with a different ordering code — check the suffix for temperature range and packaging differences.
