Notes to

Cyclone II devices contain POR circuitry to keep the device in a reset state
until the power supply voltage levels have stabilized during power-up.
The POR circuit monitors the V
I/O pins until the V
addition, the POR circuitry also monitors the V
banks that contains configuration pins (I/O banks 1 and 3 for EP2C5 and
EP2C8, I/O banks 2 and 6 for EP2C15A, EP2C20, EP2C35, EP2C50, and
EP2C70) and tri-states all user I/O pins until the V
recommended operating levels.
After the Cyclone II device enters user mode, the POR circuit continues to
monitor the V
user mode can be detected. If the V
point during user mode, the POR circuit resets the device. If the V
voltage sags during user mode, the POR circuit does not reset the device.
"Wake-up" Time for Cyclone II Devices
In some applications, it may be necessary for a device to wake up very
quickly in order to begin operation. The Cyclone II device family offers
the Fast-On feature to support fast wake-up time applications. Devices
that support the Fast-On feature are designated with an “A” in the
ordering code and have stricter power up requirements compared to non-
A devices.
