Unused GPIO Connections in the FX1/FX2/FX2LP

Version 1
    Question: The CY7C68013 EZ-USB FX2 has four GPIO ports on the 128-pin part. Can the unused GPIO pins be left open or should they have some type of termination?

     

    Answer:

    Unused GPIO pins should be tied to ground. Floating inputs can cause unnecessary noise and power consumption.
