CI industrial/commercial

[Marius]

Bonjour,

What is the difference between a circuit qualified as industrial (-40°
+85°) and commercial (0° +70°)
There are technological differences or only tests ?
Tests are unitary (??) or only on samples ?

What is the risk to use a memory sram commercial between -20 to 50° ?

thank you

Only tests (and specs).

Depends. Some specs are only "guaranteed by design" and are never tested.
Others are tested on each unit.

What is the risk to use a memory sram commercial between -20 to 50° ?

Commercial == 0 to 70? I think it depends on how critical the application is,
whether I'd even try it. It probably would work, though likely wouldn't meet
timing specs. If you have a lot of slop in the timing, there's a good chance
it'll work.
