Chapter 1: Cyclone III Device Datasheet

1–5

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.

For more information about power estimation tools, refer to the PowerPlay Early Power

Estimator User Guide and the PowerPlay Power Analysis chapter in the Quartus II

Handbook.

Notes to Table 1–4:

(1) This value is specified for normal device operation. The value varies during device power-up. This applies for all

_CCIOsettings (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.

Table 1–5 lists bus hold specifications for Cyclone III devices.
