The official line is that the 'A' (or 'B','C') parts are
'silicon shrinks' meaning that the die was redesigned to
make it smaller and cheaper.

In reality these redesigns are also bug fixes. Except
for the 'old' windowed parts, these versions are
usually better and cheaper.

And most "A" parts fixed a high-speed baud rate generation bug, an A/D bug,
and added the brown-out reset.

But just to confuse you, some 'A' parts ARE different, in particular
the 73A and 74A have brownout, and the config fuse layout is
different. I think they quickly realised this would confuse people, so
instead of the '71A, they introduced the 710 and 711.
On the 5x series, there's no difference you need to worry about
(except price!)
