What this NOR Flash was designed for
The Infineon S25FL116K0XNFB013 is a 16 Mbit SPI NOR Flash memory from the Automotive series, qualified to AEC-Q100 for automotive-grade reliability. It stores firmware, calibration tables, and boot code in engine control units, transmission controllers, and other vehicle electronics where non-volatile storage must survive vibration and temperature extremes.
16 Mbit density — sizing the storage budget
Organized as 2 M x 8 bits, the 16 Mbit capacity fits firmware images up to about 2 MB uncompressed. For automotive ECUs running a real-time OS with calibration maps, this is a mid-range density — enough for a single bootloader plus application image, but tight if you need over-the-air staging or redundant banks. The 3 ms page write cycle means bulk programming takes roughly 1.5 seconds for a full chip erase and rewrite, which is typical for this NOR generation.
No further factory orders are accepted, and no last-time-buy window remains open. For production sustainment, the part must be sourced through independent distribution or surplus channels. If your design is still in the prototype phase, a pin-compatible replacement from the same family should be evaluated. For existing production, we can quote against your annual volume to secure remaining inventory.
Package and temperature — board-fit check
The 8-SOIC package (0.209" body width, 5.30 mm) is a standard narrow SOIC footprint shared by many SPI NOR Flash parts.
