From what I understand, the vulnerability of a chip has to do with the operating voltage of the chip. As chips have become smaller, and more efficient, they have also become less vulnerable to EMP. Higher voltage components are more vulnerable, like the motors, but I don't think you are going to get a man-portable device that will damage them. Maybe one that would fit in a vehicle, but you would have to be very close (inverse square law) and you would have to find a way to not fry your own vehicle.
Not a chip designer, nor an electrician, if anyone with more credibility wants to jump in here, please do.
