I/O Standard Specifications
Tables in this section list the input voltage (VIH and VIL), output voltage (VOH and VOL), and current drive characteristics (IOH
and IOL) for various I/O standards supported by Cyclone V devices.
You must perform timing closure analysis to determine the maximum achievable frequency for general purpose I/O standards.

Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO
Valid with ±10% tolerances to cover changes over PVT.
