I was going to try a dsPIC that's 70 MIPs, and has 14 or 16 PWM channels I believe, and can do 8 simultaneous A/D conversions. It's designed for driving 2 ACIMs or PMSMs. 512k of program flash and 56k of data memory I think. It's the dspic33ep series, which has a bunch to choose from. I just wasn't thrilled with using a 3.3v micro.
