What this NOR flash does on the board
The S25FL164K0XNFI013 is a 64 Mbit NOR flash from Infineon's FL1-K series, built for code shadowing, configuration storage, and execute-in-place (XIP) in embedded systems.
Infineon lists the S25FL164K0XNFI013 as Obsolete. That means no new production runs from the factory. If you have this on a BOM for an active design, you need to plan a last-time buy or qualify a replacement before existing stock dries up. We can source this part through our independent supply network — quotes are against your specific quantity and date code needs.
Key parametrics for the design engineer
Memory organisation is 8 M x 8 bits — that is 64 Mbit in a byte-wide array. Page write cycle time is 3 ms typ, which matters for OTA firmware updates where you are writing many pages sequentially. Fine for factory automation, outdoor telecom cabinets, and instrumentation where the board stays above -40°C.
