Electrical Characteristics

Recommended Operating Conditions

This section lists the functional operation limits for AC and DC parameters for

Cyclone III devices. The steady-state voltage and current values expected from

Cyclone III devices are provided in

All supplies must be strictly monotonic

without plateaus.

Notes to

(1) V

CCIO

for all I/O banks must be powered up during device operation. All V

CCA

pins must be powered to 2.5 V (even when PLLs are not used), and

must be powered up and powered down at the same time.

(2) V

CCD_PLL

must always be connected to V

CCINT

through a decoupling capacitor and ferrite bead.

(3) The V

CC

must rise monotonically.

(4) All input buffers are powered by the V

CCIO

supply.

(5) POR time for Standard POR ranges between 50–200 ms. Each individual power supply should reach the recommended operating range within

50 ms.

(6) POR time for Fast POR ranges between 3–9 ms. Each individual power supply should reach the recommended operating range within 3 ms.
