Futaba a long time ago, early '90s maybe, advertised 1024 step radios with some of their early digital units, and I think servos. Believe I saw an ad for some of their newer servos a while back claiming higher resolution, 4096 seems to come to mind, but I'm not sure.

I suspect most any decent equipment has well over 100 steps, but again not positive.
