I was looking at the AT90S2333, but looking again, I see the AT90LS4433
which is interesting.  I may try them for the next project, but I think I'm
locked into PIC right now even though I'm kinda pissed at Mchip.  The cost
I'm looking at for 63A's is in the $2.50 range which is hard to beat.  The
problem is that my A->PWM circuit with isolation will cost around $4-$5 per
channel.  Its basically a couple of op-amps driving MOSFETS going to an
opto-isolator.  We are measuring current and get into ground loop problems
because of down-stream current measurers.  The circuit is supposed to be
able to act as a "line sniffer" and measure mA level currents in a wire.
