Stratix III devices offer a new power supply, V
configuration pins and dual function pins. Configuration voltage
supported is 1.8 V, 2.5 V, 3.0 V, and 3.3 V. Stratix III devices do not
support 1.5 V configuration.
Use this pin to power all dedicated configuration inputs, dedicated
configuration outputs, dedicated configuration bidirectional pins, and
some of the dual functional pins that you use for configuration. With

with the regular I/O buffer in Stratix III devices.
The operating voltage for the configuration input pin is independent of
the I/O banks power supply V
no configuration voltage constraints on V
devices.
V
Stratix III devices have a dedicated programming power supply, V
which must be connected to 3.3 V/3.0 V/2.5 V in order to power the I/O
pre-drivers, the JTAG input and output pins (TCK, TMS, TDI, TDO and
TRST), and the design security circuitry.

within this specified time, your Stratix III device will not
configure successfully. If your system does not allow ramp-up
time of 100 ms or less, you must hold nCONFIG low until all
power supplies are stable.
