For Cyclone II devices, wake-up time consists of power-up, POR,
configuration, and initialization. The device must properly go through all
four stages to configure correctly and begin operation. You can calculate
wake-up time using the following equation:

characteristics and the power supply used in your system. The fast-on
devices require a maximum V
POR time of 12 ms.
Configuration time will depend on the configuration mode chosen and
the configuration file size. You can calculate configuration time by
multiplying the number of bits in the configuration file with the period of
the configuration clock. For fast configuration times, you should use
Passive Serial (PS) configuration mode with maximum DCLK frequency
of 100 MHz. In addition, you can use compression to reduce the
configuration file size and speed up the configuration time. The t
