92 / 168 page  5–2 Altera Corporation Cyclone II Device Handbook, Volume 1 February 2008 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. Table 5–2. Recommended Operating Conditions Symbol Parameter Conditions Minimum Maximum Unit VCCINT Supply voltage for internal logic and input buffers (1) 1.15 1.25 V VCCIO (2) Supply voltage for output buffers, 3.3-V operation (1) 3.135 (3.00) 3.465 (3.60) (3) V Supply voltage for output buffers, 2.5-V operation (1) 2.375 2.625 V Supply voltage for output buffers, 1.8-V operation (1) 1.71 1.89 V Supply voltage for output buffers, 1.5-V operation (1) 1.425 1.575 V TJ Operating junction temperature For commercial use 0 85 °C For industrial use –40 100 °C For extended temperature use –40 125 °C For automotive use –40 125 °C 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. |
