Product details

128 Mbit NOR Flash for code shadowing and data logging

The S25FS128SDSNFI101 is a 128 Mbit NOR Flash memory from the FS-S series, organized as 16M x 8 bits. It uses a SPI interface with Quad I/O and QPI support, clocked at 80 MHz.

Package and mounting — 8-WSON with exposed pad

The 8-WSON package (5x6 mm) is a small-outline no-lead with an exposed pad on the bottom. The pad must be soldered to a thermal land on the PCB for heat dissipation.

Lifecycle and sourcing

The S25FS128SDSNFI101 is listed as Active in production. It is ROHS3 compliant. The part is available through independent distribution; pricing and stock levels are confirmed at quote time against an RFQ. For dual-sourcing or higher-density requirements, the S25FS512SAGNFI011 (512 Mbit, 133 MHz) is a functional upgrade in the same FS-S family, but check the supply voltage and package compatibility.

Frequently asked questions

Is S25FS128SDSNFI101 RoHS compliant?

Yes, it is ROHS3 compliant.

What is the equivalent or replacement for S25FS128SDSNFI101?

There is no direct pin-compatible second source listed. Within the same FS-S family, the S25FS512SAGNFI011 offers higher density (512 Mbit) and a faster 133 MHz clock, but check the supply voltage and package compatibility. For a 128 Mbit alternative at 3V, consider the S25FL128SAGNFI011 from the FL-S series, which runs at 133 MHz and 2.7V-3.6V supply.
