The S25FL128P0XNFI000: Typical applications include firmware storage, configuration data, and OTA staging in industrial controllers, telecom line cards, and outdoor networking equipment.
104 MHz SPI – read throughput and bus margin
The 104 MHz clock rate on the SPI bus gives a raw serial read throughput around 13 MB/s in single-bit mode, or roughly 52 MB/s if the host controller supports Quad-SPI. That bandwidth is enough for fast boot loading or shadowing code into RAM without stalling the processor. The 3 ms page write time (typical) means bulk programming takes a few seconds for a full 128 Mbit device – budget that into production test flow.
Obsolete – sourcing reality
This part carries an official Obsolete lifecycle status. For BOM lines that still need this exact footprint and density, supply runs through independent distribution and surplus inventory.
Package and layout – 8-WSON exposed pad
The 6x8 mm footprint is smaller than an SOIC-8, so check the pick-and-place nozzle clearance against adjacent tall components.
