64 Mbit of automotive-grade NOR Flash in a hand-solderable SOIC-8
It talks over a Quad SPI / QPI interface at up to 108 MHz, which means you can shadow code or stage OTA updates without waiting on a slow serial bus.
The 108 MHz clock rate on the Quad SPI interface gives a theoretical throughput around 54 MB/s in quad-read mode. That's enough to feed a Cortex-M7 or an i.MX RT part without the CPU stalling on instruction fetches. The part also supports QPI (Quad Peripheral Interface) where the command and address phases also use four I/O lines, cutting command overhead. If your MCU has a Quad-SPI controller with a 108 MHz-capable clock tree, this part will keep up without wait-state headaches.
AEC-Q100: why it matters for the BOM
It's not just a commercial-grade die in a nicer package — the silicon and the assembly are qualified for the thermal and vibration profile of automotive electronics. If you're designing a body controller, a telematics unit, or an ADAS peripheral that needs non-volatile storage, this part fits the reliability budget without requiring a separate qualification run.
Temperature grade: 85°C vs 125°C variants
That covers most passenger-cabin and industrial environments. If your design needs 125°C operation — under-hood, engine bay, or downhole — the sibling S25FL064LABMFM013 carries the same 64 Mbit density and 108 MHz speed but extends the temperature range to 125°C. The package and pinout are identical, so a board layout can support both with a single BOM option change.
The ROHS3 compliance is current, and the series has a long tail of package and density variants for second-sourcing flexibility.
