Cyclone II Device Handbook, Volume 1
Hot Socketing & Power-On Reset
If you cannot meet the maximum VCC ramp time requirement, you must
use an external component to hold
nCONFIG low until the power supplies
have reached their minimum recommend operating levels. Otherwise,
the device may not properly configure and enter user mode.
Conclusion
Cyclone II devices are hot socketable and support all power-up and
power-down sequences with the one requirement that VCCIO and VCCINT
be powered up and down within 100 ms of each other to keep the I/O
pins from driving out. Cyclone II devices do not require any external
devices for hot socketing and power sequencing.
