Pin Capacitance
The definitions for the equation are as follows:
•
•
•
•
•
•
The ROCT value calculated shows the range of OCT resistance with the variation of temperature and VCCIO
RSCAL is the OCT resistance value at power-up.
.
ΔT is the variation of temperature with respect to the temperature at power up.
ΔV is the variation of voltage with respect to the VCCIO at power up.
dR/dT is the percentage change of RSCAL with temperature.
dR/dV is the percentage change of RSCAL with voltage.

Internal Weak Pull-Up and Weak Pull-Down Resistor
All I/O pins, except configuration, test, and JTAG pins, have an option to enable weak pull-up. The weak pull-down feature is only available for the
pins as described in the Internal Weak Pull-Down Resistor Values for Arria 10 Devices table.
