It uses the SPI Quad I/O interface, which lets it push read throughput beyond standard SPI — useful for fast code shadowing or FPGA configuration where the CPU boots from serial Flash. The 133 MHz clock frequency gives a practical read rate that keeps the bus margin comfortable in most embedded designs. The part operates from a 2.7 V to 3.6 V supply and is rated for -40°C to +85°C.

Frequently asked questions
What is the replacement for S25FL128SAGMFIG10?
No official replacement has been announced because the part is still active. If you need a higher-density variant, check the FL-S series for 256 Mbit options in the same 16-SOIC footprint.
Is S25FL128SAGMFIG10 compatible with S25FL128SAGMFI10?
The S25FL128SAGMFIG10 and S25FL128SAGMFI10 share the same base product number and 128 Mbit density, but the suffix differences may indicate variations in package, temperature range, or speed grade. Verify the full order code against your BOM before substituting.
What is the operating voltage of S25FL128SAGMFIG10?
The supply voltage range is 2.7 V to 3.6 V, making it compatible with standard 3.3 V logic systems.
