DC Characteristics
This section lists the I/O leakage current, pin capacitance, on-chip termination (OCT)
tolerance, and bus hold specifications for Cyclone III LS devices.
Supply Current
Supply current is the current the device draws after the device is configured with no
inputs or outputs toggling and no activity in the device. Use the Excel-based Early
Power Estimator (EPE) to get the supply current estimates for your design because
these currents vary largely with the resources you use.
