Is that last entry ever useful? Do all those controllers
have something in common?

Is this one a superset of the previous one? If so,
put both names in.

It's better to say 440 than 44x, maybe all "441" parts
will be totally different. I don't know what to do
with 40x; maybe say 405 as that seems to be the most
common chip. OTOH, you don't have to deal with that
right now :-)
