Device: Arria® V


The VCC_HPS pin in Arria V SoC devices is the power supply pin for the Hard Processor System (HPS).
The Pin Connection Guideline says 1.15 V supply for the I3 speed grade, but older device datasheets say 1.1 V supply.
For the I3 speed grade, supplying 1.15 V to the VCC_HPS pin is the correct treatment.
Note that it is supplied at 1.1 V for non-I3 speed grades.

The device datasheet has already been revised and corrected to the correct description.
Please be careful if you are looking at the device datasheet of ver 3.7 or earlier.
