Just a quick question in reference to the datasheet of K20 sub-family document number "K20P144M120SF3". Looking at page 73 for pin assignments.
I am using the 144 pin LQFP package, and I had a question about the pins that are NC (not connected) on my IC, e.g. C10, M5, A10, B10.
Do these pins not have a physical electrical connection to the IC? what happens if I connect 5V to any of these pins? Can anything go wrong If I leave this pin floating? Thanks in advance
