    Hey Jun-San,

    Just for my understanding, may I ask what you're intention is for connecting 3.3V to the NC pin?

    "Is it OK to connect 3.3V to NC PIN?"
    Typically when we (TI) state a pin is No Connect, it means that the pin does not have bond wires connecting it to the actual die of the device. So this means the NC pin is essentially floating. So connecting a 3.3V rail to this should not have any affect other than maybe picking up noise.

    Thanks,
    -Bobby
