Product details

128 Mbit NOR Flash with Quad-SPI — what the 80 MHz clock buys you

At that clock rate, Quad-SPI read throughput is roughly 40 MB/s in fast-read quad-output mode — enough to support execute-in-place (XIP) for a microcontroller or FPGA configuration store without a separate DRAM cache.

16-SOIC footprint — layout and rework notes

The wide-body SOIC is easier to hand-rework than QFN or BGA alternatives — useful during prototyping or if a rework-lab tech needs to swap parts after a firmware revision.

Frequently asked questions

Is S25FL128SDSMFBG00 active or obsolete?

Active. The product status is listed as Active, so Cypress/Infineon is still producing this part. No end-of-life notice has been issued.

What is the maximum clock frequency of S25FL128SDSMFBG00?

The SPI clock frequency is rated at 80 MHz. In Quad I/O mode this gives a read throughput in the ballpark of 40 MB/s.
