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

Notes to Table 5–2:
(1)
The VCC must rise monotonically. The maximum VCC (both VCCIO and VCCINT) rise time is 100 ms for non-A devices
and 2 ms for A devices.
(2)
The VCCIO range given here spans the lowest and highest operating voltages of all supported I/O standards. The
recommended VCCIO 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 VCCIO 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.
