5.1.12. Unused Pins

There are specific guidelines for unused pins connections and reserved state settings. Intel® Agilex™ devices support several options of reserved state settings, to allow flexibility in the board design.

No Connect (NC) Pins

For vertical device migration, where the device package is the same but contains different density, you can leave the NC pins floating or connect to Vccio or to ground. You can refer to the device pin-out files for a list of NC pins.

Do Not Use (DNU) Pins

Do not connect these pins to power, ground, or any other signal. DNU pins must be left floating.
