The Arria II 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
supplies for I/O banks 3C and 8C in Arria II GX devices, 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
the power supplies reach their full-rail values to release the device from the reset
state.
The POR circuitry monitors V
Arria II GZ devices. The POR circuitry keeps the Arria II GZ devices in reset state
until the power supply outputs are within operating range (provided that the V
powers up fully before V
POR circuitry is important to ensure that all the circuits in the Arria II 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.
