Board Design Considerations
Device Power-up
© November 2008 Altera Corporation
f
In many applications, knowing the power-up behavior of your device is critical,
especially when you are inserting or removing the board in a system during system
operation. Considerations include I/O behaviors and the conditions of supplies and
timing. Review the conditions and considerations discussed in this section before you
begin with board design and configuration setup to ensure a successful
implementation of Cyclone III devices in your design.
Technology
Cyclone III devices are designed with hot-socketing and power-on reset (POR)
circuitry that regulates the power-up sequencing of the device prior to configuration.
These circuitries ensure that Cyclone III devices are ready for configuration while
taking care of uncertainties on device interfaces during these stages. These also enable
the Cyclone III device to be hot-swapped without the use of any external devices.
Figure 1
For more details about hot socketing and power-on reset circuit operation, refer to the
Hot Socketing and Power-On Reset in Cyclone III Devices
Cyclone III Device Handbook.
