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 Table 1–3. All supplies must be strictly monotonic
without plateaus.

Notes to Table 1–3:
(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.
