The Arria II GX power-on reset (POR) circuitry generates a POR signal to keep the
device in the reset state until the power supply’s voltage levels have stabilized during
power-up. The POR circuitry monitors V
banks 3C and 8C, where the configuration pins are located. The POR circuitry
tri-states all user I/O pins until the power supplies reach the recommended operating
levels. These power supplies are required to monotonically reach their full-rail values
without plateaus and within the maximum power supply ramp time (t
POR circuitry de-asserts the POR signal after the power supplies reach their full-rail
values to release the device from the reset state. On power down, brown-out occurs if

threshold voltage.
POR circuitry is important to ensure that all the circuits in the Arria II GX device are at
certain known states during power up. You can select the POR signal pulse width
between fast POR time or standard POR time using the MSEL pin settings. For fast
POR time, the POR signal pulse width is set to 4 ms for the power supplies to ramp up
to full rail. For standard POR time, the POR signal pulse width is set to 100 ms for the
power supplies to ramp up to full rail. In both cases, you can extend the POR time
with an external component to assert the nSTATUS pin low.
For more information about the POR specification, refer to the
Datasheet.
