Product details

128 Mbit SPI NOR Flash with Quad I/O at 1.7 V

The Cypress S25FS128SAGNFI003 is a 128 Mbit (16M x 8) SPI NOR Flash memory from the FS-S series, supporting both Quad I/O and QPI interfaces at a clock rate of 133 MHz.

133 MHz read throughput and interface flexibility

The 133 MHz clock rate delivers a sustained read throughput of up to 532 Mbps in Quad I/O mode (four data lines). The QPI mode reduces command overhead by using the SPI bus for both address and data, which improves random-read efficiency. For a firmware-bringup engineer, the first-power checklist includes verifying the SPI mode (Mode 0 or Mode 3) matches the host controller and that the 1.7 V supply is within tolerance before enabling quad reads.

For a BOM cost engineer, this avoids single-source risk flags and LTB surcharges.

Frequently asked questions

Can S25FS128SAGNFI003 be used as a replacement for S25FS128SAGNFI001?

The S25FS128SAGNFI003 and S25FS128SAGNFI001 share the same die and package; the suffix difference typically indicates packaging or shipping medium. Verify the specific suffix meaning in the datasheet, but functionally they are the same 128 Mbit SPI NOR Flash device.
