AEC-Q100 qualification is the gate for any automotive ECU, ADAS module, or chassis-domain controller. It means the part passed the full stress suite — high-temperature operating life, temperature cycling, ESD, latch-up — and carries a PPAP-ready data package. If your BOM targets a passenger-vehicle or heavy-equipment program, this is the tier that avoids a qualification waiver or a costly re-spin. The -40°C to 85°C operating range covers cabin and most under-hood locations; if you need the extended -40°C to 125°C variant, look at the S25FL064LABNFM010 or S25FL064LABMFM000 — same 64 Mbit, same 108 MHz, same footprint, wider temperature grade.
Package and mounting — 8-WSON (5x6 mm)
The 8-WSON with exposed pad is a surface-mount package that measures 5 mm x 6 mm. The pad pitch is fine enough that a standard chisel tip works, but a hot-air station is cleaner. The package is RoHS3 compliant.
