output levels are compatible with systems of the same voltage as the
power supply (i.e., when V
supply, the output levels are compatible with 1.5-V systems). When V
pins are connected to a 3.3-V power supply, the output high is 3.3-V and
is compatible with 3.3-V or 5.0-V systems.
Cyclone MultiVolt I/O support.
Because Cyclone devices can be used in a mixed-voltage environment,
they have been designed specifically to tolerate any possible power-up
sequence. Therefore, the V
powered in any order.
Signals can be driven into Cyclone devices before and during power up
without damaging the device. In addition, Cyclone devices do not drive
out during power up. Once operating conditions are reached and the
device is configured, Cyclone devices operate as specified by the user.
