Operating Conditions
Table 5–2 specifies the recommended operating conditions for Cyclone II
devices. It shows the allowed voltage ranges for V_CCINT, V_CCIO, and the
operating junction temperature (T_J). The LVTTL and LVCMOS inputs are
powered by V_CCIO only. The LVDS and LVPECL input buffers on
dedicated clock pins are powered by V_CCINT. The SSTL, HSTL, LVDS
input buffers are powered by both V_CCINT and V_CCIO.

Notes to Table 5–2:
(1) The V_CC must rise monotonically. The maximum V_CC (both V_CCIO and V_CCINT) rise time is 100 ms for non-A devices
and 2 ms for A devices.
(2) The V_CCIO range given here spans the lowest and highest operating voltages of all supported I/O standards. The
recommended V_CCIO range specific to each of the single-ended I/O standards is given in Table 5–6, and those
specific to the differential standards is given in Table 5–8.
(3) The minimum and maximum values of 3.0 V and 3.6 V, respectively, for V_CCIO only applies to the PCI and PCI-X
I/O standards. Refer to Table 5–6 for the voltage range of other I/O standards.
