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.
