64 Mbit NOR Flash on a Quad SPI bus
It communicates over a standard SPI bus with Quad I/O and QPI protocol support, clocking up to 108 MHz. The 2.7 V to 3.6 V supply range and -40°C to 85°C industrial temperature rating make it a fit for outdoor telecom gear, factory automation controllers, and embedded systems that need a reliable code-storage or data-logging memory.
At 108 MHz with Quad I/O, the S25FL064LABMFI000 can sustain read throughput in continuous-read mode. That matters for a system that shadows firmware into RAM at power-up or streams large lookup tables from Flash.
For a BOM that needs a qualified serial NOR Flash with a stable supply outlook, this part does not introduce obsolescence risk. The FL-L series is a mature, well-established product line with broad distribution support.
It is not rated for under-hood or downhole environments, but it handles the thermal swings of a factory floor, an outdoor telecom cabinet, or a rooftop solar inverter.
