Notes to Table 4â3:
(1) Supply voltage specifications apply to voltage readings taken at the device pins, not at the power supply.
(2) During transitions, the inputs may overshoot to the voltage shown in Table 4â2 based upon the input duty cycle.
The DC case is equivalent to 100% duty cycle. During transitions, the inputs may undershoot to â2.0 V for input
currents less than 100 mA and periods shorter than 20 ns.
(3) Maximum VCC rise time is 100 ms, and VCC must rise monotonically from ground to VCC.
(4) VCCPD must ramp-up from 0 V to 3.3 V within 100 μs to 100 ms. If VCCPD is not ramped up within this specified
time, the Stratix II GX device will not configure successfully. If the system does not allow for a VCCPD ramp-up time
of 100 ms or less, hold nCONFIG low until all power supplies are reliable.
(5) All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before VCCINT, VCCPD, and VCCIO
are powered.
(6) VCCIO maximum and minimum conditions for PCI and PCI-X are shown in parentheses.

not violated.
