Routing delays are for typical designs across worst-case operating conditions. These parameters should be used for estimating device
performance. Post-route timing analysis or simulation is required to determine actual worst-case performance. Post-route timing is based
on actual routing delay measurements performed on the device prior to shipment.
CC
= 3.0 V for 3.3V specifications.
