Cyclone III device family contains POR circuitry to keep the device in a reset state
until the power supply voltage levels have stabilized during power up. During POR,
all user I/O pins are tristated until the V
In addition, the POR circuitry also ensures the V
that contains configuration pins reach an acceptable level before configuration is
triggered.
The POR circuit of the Cyclone III device monitors the V
during power-on. The enhanced POR circuit of the Cyclone III LS device includes
monitoring V
level.
The V
for Cyclone III LS devices only. Cyclone III devices do not have V
After Cyclone III device family enters user mode, the POR circuit continues to
monitor the V
detected. If the V
mode, the POR circuit resets the device. If the V
the POR circuit does not reset the device.
In some applications, it is necessary for a device to wake up very quickly to begin
operation. Cyclone III device family offers the Fast-On feature to support fast
wake-up time applications. For Cyclone III device family, the MSEL[3..0] pin
settings determine the POR time (t
9 ms, while standard POR ranges from 50 ms to 200 ms.
