Internal Weak Pull-Up Resistor
Table 13 lists the weak pull-up resistor values for Cyclone V devices.
All I/O pins have an option to enable weak pull-up except the configuration, test, and
JTAG pins. For more information about the pins that support internal weak pull-up
and internal weak pull-down features, refer to the Cyclone V Device Family Pin
Connection Guidelines.

Notes to Table 13:
(1) Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO
.
(2) These specifications are valid with 10% tolerances to cover changes over PVT.
I/O Standard Specifications
Table 14 through Table 19 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.
For an explanation of terms used in Table 14 through Table 19, refer to “Glossary” on
page 1–59.
