Electrical Characteristics
DC Characteristics
This section lists the I/O leakage current, pin capacitance, on-chip termination (OCT)
tolerance, and bus hold specifications for Cyclone III devices.
Supply Current
Standby 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 used. Table 1–4 lists I/O pin leakage
current for Cyclone III devices.

(1) This value is specified for normal device operation. The value varies during device power-up. This applies for all
V CCIO settings (3.3, 3.0, 2.5, 1.8, 1.5, and 1.2 V).
(2) 10 ? A I/O leakage current limit is applicable when the internal clamping diode is off. A higher current can be the
observed when the diode is on.
Bus Hold
Bus hold retains the last valid logic state after the source driving it either enters the
high impedance state or is removed. Each I/O pin has an option to enable bus hold in
user mode. Bus hold is always disabled in configuration mode.
