I was half joking. I said: "The chance that **YOU** get killed by 5V
is small." I mean as long as you are alive, you can try another F1121
again. Hope I did not cause you any damage. I apologize.

About a year ago I accidentally powered a '1121 up with 5V.
It didn't work on 5V, but was fine after correcting the supply.

I once ran a 5V 68HC11 on 9.6V (Nicap pack), and powered it
off after a minute or two because it was so hot. That was a
rare windowed chip, which was afterwards fine, *except* for
the internal charge pump that produces the EEPROM programming
voltage. Presumably 5V * Ratio was too much for something.

So even if you don't get total failure on over-volting an MSP,
I wouldn't trust it and certainly wouldn't ship it. Partial
failure might be initially invisible.
