Internal Weak Pull-Up Resistor

All I/O pins, except configuration, test, and JTAG pins, have an option to enable weak pull-up.

Table 14.  Internal Weak Pull-Up Resistor Values for Cyclone® V Devices
Symbol Description Condition (V)16 Value17 Unit
RPU 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. VCCIO = 3.3 ±5% 25
VCCIO = 3.0 ±5% 25
VCCIO = 2.5 ±5% 25
VCCIO = 1.8 ±5% 25
VCCIO = 1.5 ±5% 25
VCCIO = 1.35 ±5% 25
VCCIO = 1.25 ±5% 25
VCCIO = 1.2 ±5% 25
16 Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO.
17 Valid with ±10% tolerances to cover changes over PVT.
