I'm looking at some cool DIP package parts in the 16 bit series.

This is what I've narrowed it down to:

The 5v parts have less flash and RAM than my 18F2620 - so I'll just
stick with 3.3 V parts - I don't mind.

Also, I've googled for this, but can't find a satisfactory
explanation. What are DSP instructions?
