Re: Part II: Picking the Right MCU for Your Application

NO RATINGS
Q:  On my application power consumption is not an issue.  I'm more interested if anyone has experience with EMC testing.  Inputs tend to bounce when subjected to voltage spikes.  3.3volt mcu has less tolerance for input bouncing than 5.0volt mcu.

A: There are PCB design guidelines that help minimize the effects of EMI, which would require another course and is a good topic.  You can use some shielding and geround planes, ferrite filters on external signals, proper grounding, elimination of ground loops, and so on.  You can find a lot of practical information on the Internet.
