The part operates from a 2.7 V to 3.6 V supply and is rated for the industrial temperature range of -40°C to 85°C. It comes in a 16-SOIC wide-body package (7.50 mm width) and is surface-mount only.
Industrial temperature range — know the limit
If your application pushes beyond 85°C ambient — under-hood automotive, downhole tools, or near a hot processor — the S25FL128SAGMFV001 variant extends the range to 105°C. Otherwise, this part fits the standard industrial bill.
That means the manufacturer is still producing it, no last-time-buy has been announced, and the part is available through franchised and independent distribution. For a BOM line, this is a low-risk component to qualify into a new design.
