128 Mbit NOR Flash on SPI Quad I/O — what it fits
For a factory-floor PLC or a base-station line card, the 85°C ceiling is adequate and keeps the BOM cost lower than the extended-temperature sibling.
Cross-reference note
The S25FL128SAGMFV001 is the same 128Mbit FL-S die in the same 16-SOIC package, but rated for -40°C to 105°C.
