I'm not sure about that--PICs definitely use less power than
traditional TTL and so probably don't have the issues with heat.
They also have smaller features, so perhaps the current density is
similar.
There's a TI demo of a couple of their 430 uCs that demonstrates
sleep-mode current consumption of 0.4 uA. That would be hard to
match with any bipolar logic family.
