Product details

128 Mbit NOR Flash with Quad-SPI — what the 108 MHz clock buys you

The S25FL127SABMFI103: For a firmware engineer, that translates to faster boot times and smoother XIP (eXecute-In-Place) performance — the flash keeps up with the CPU without stalling for cache refills.

If your design lives in a server room or consumer appliance, the 85°C ceiling is comfortable; for engine-bay or downhole applications, step up to the 105°C variants (S25FL127SABMFV101 or S25FL127SABMFV100) in the same FL-S family.

Housed in an 8-SOIC (0.209", 5.30 mm width) package, surface-mount only.

The FL-S series is a current-generation NOR Flash family from Infineon, with broad distribution coverage. For dual-sourcing or a wider temperature grade, the S25FL127SABMFV101 (Tube, -40°C to 105°C) and S25FL127SABMFV100 (Tray, same temp range) are pin-compatible siblings within the same base part number S25FL127. No functional second-source from another manufacturer is documented in this listing.

Frequently asked questions

What is the memory size and interface of the S25FL127SABMFI103?

It is a 128 Mbit NOR Flash organized as 16M x 8 bits, with an SPI Quad I/O interface. The Quad I/O allows four-bit-wide data transfers at up to 108 MHz, giving effective read throughput well above a standard SPI part.

What are the S25FL127SABMFI103 equivalent or alternative parts?

Within the same FL-S series and base part number S25FL127, the S25FL127SABMFV101 (Tube, -40°C to 105°C) and S25FL127SABMFV100 (Tray, same extended temp range) are pin-compatible alternatives.
