Configuration Pins
All dedicated configuration pins are supplied by V_CCIO for I/O banks 3C and 8C in
which they reside. The supported configuration voltages are 1.8, 2.5, 3.0, and
3.3 V. Use the V_CCIO pin for I/O banks 3C and 8C to power all the dedicated
configuration inputs, dedicated configuration outputs, and dedicated
configuration bidirectional pins that you used for configuration. With V_CCIO for
I/O banks 3C and 8C, the configuration input buffers do not have to the share
power lines with the regular I/O buffer.
You must power the dual function configuration pins that you used for
configuration with the V_CCIO power supply in which the configuration pins reside.
For more information about the configuration voltage standard applied to the
V_CCIO power supply, refer to Table 9–6 on page 9–9.
All dedicated configuration pins and dual-function pins are supplied by V_CCPGM.
The supported configuration voltages are 1.8, 2.5, and 3.0 V. Use the V_CCPGM pin
to power all the dedicated configuration inputs, dedicated configuration outputs,
and dedicated configuration bidirectional pins that you used for configuration.
With V_CCPGM , the configuration input buffers do not have to share the power lines
with the regular I/O buffer.
Arria II devices do not support a 1.5-V configuration. The operating voltage for the
configuration input pin is independent of the I/O banks power supply V_CCIO during
configuration. Therefore, for Arria II devices, you do not require configuration
voltage constraints on V_CCIO.
