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.

Symbol
Description
Conditions (V) ⁽¹⁾
V_CCIO = 3.3 ±5%
V_CCIO = 3.0 ±5%
V_CCIO = 2.5 ±5%
R_PU
Value of the I/O pin pull-up resistor before and during
configuration, as well as user mode if you have enabled the
programmable pull-up resistor option.
V_CCIO = 1.8 ±5%
V_CCIO = 1.5 ±5%
V_CCIO = 1.35 ±5%
V_CCIO = 1.25 ±5%
V_CCIO = 1.2 ±5%
Notes to Table 13:
(1) Pin pull-up resistance values may be lower if an external source drives the pin higher than V_CCIO.
(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 (V_IH and V_IL), output voltage (V_OH and
V_OL), and current drive characteristics (I_OH and I_OL) 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 1–54.
