Product details

The Cypress (Infineon) S25FL128SDPNFI000 is a 128 Mbit serial NOR Flash from the FL-S family, organised as 16M x 8 bits.

At 66 MHz, the Quad I/O interface delivers about 33 MB/s in continuous read. That is enough to feed a Cortex-M or low-end application processor without stalling on instruction fetch, as long as the flash controller on the SoC supports Quad I/O and the layout keeps the SPI traces short. If the design needs faster throughput — for example, a higher-resolution display frame buffer or a faster CPU — the 133 MHz siblings in the FL-S family (S25FL128SAGMFV010, S25FL128SAGBHIA10) are worth a look, though they may trade off package or temperature range.

Package and footprint — 8-WSON with exposed pad

The part comes in an 8-WDFN Exposed Pad, supplier package designation 8-WSON (6x8 mm).

Active lifecycle — no near-term end-of-life pressure

For designs that need a second source, the FL-S family includes several 128 Mbit variants with the same base number (S25FL128) — the S25FL128SDSNFI000 (80 MHz, same package) and the S25FL128SAGMFV010 (133 MHz, -40 to 105°C, different package) — but none is a drop-in pin-compatible alternate without checking the footprint and temperature grade.

Frequently asked questions

What is the memory size and interface of S25FL128SDPNFI000?

The S25FL128SDPNFI000 is a 128 Mbit NOR Flash, organised as 16M x 8 bits.

What is the replacement or equivalent for S25FL128SDPNFI000?

There is no official replacement, since the part is still active. Within the same FL-S family, the S25FL128SDSNFI000 is a close functional equivalent — same 128 Mbit density, same 8-WSON package, but with an 80 MHz clock instead of 66 MHz. The S25FL128SAGMFV010 offers 133 MHz and an extended -40 to 105°C range but comes in a different package. Neither is a guaranteed drop-in without verifying the footprint and temperature requirements.
