Table 4–32. Stratix GX MultiVolt I/O Support
To drive inputs higher than V
inputs to the device, enable the PCI clamping diode to prevent V
The input pin current may be slightly higher than the typical value.
Although V
at a different level can still interface with the Stratix GX device if it has inputs that tolerate the V
Stratix GX devices can be 5.0-V tolerant with the use of an external resistor and the internal PCI clamp diode.
This is the external signal that is driving the Stratix GX device.
This represents the system voltage that Stratix GX supports when a VCCIO pin is connected to a specific voltage
level. For example, when VCCIO is 3.3 V and if the I/O standard is LVTTL/LVCMOS, the output high of the signal
coming out from Stratix GX is 3.3 V and is compatible with 3.3-V or 5.0-V systems.

2.5-V, or 3.3-V power supply, depending on the output requirements.
The output levels are compatible with systems of the same voltage as the
power supply (for example, when VCCIO pins are connected to a 1.5-V
power supply, the output levels are compatible with 1.5-V systems).
When VCCIO pins are connected to a 3.3-V power supply, the output high
is 3.3 V and is compatible with 3.3-V or 5.0-V systems.
Table 4–32
Because Stratix GX devices can be used in a mixed-voltage environment,
they have been designed specifically to tolerate any possible power-up
sequence. Therefore, the VCCIO and VCCINT power supplies may be
powered in any order.
Signals can be driven into Stratix GX devices before and during power up
without damaging the device. In addition, Stratix GX devices do not
drive out during power up. Once operating conditions are reached and
the device is configured, Stratix GX devices operate as specified by the
user. For more information, see the Selectable I/O Standards in Stratix &
Stratix GX Devices chapter of the Stratix GX Device Handbook, Volume 2.
