The Cyclone
hot-socketing, which is also known as hot plug-in or hot swap, and power sequencing
support without the use of any external devices. You can insert or remove Cyclone III
device family or a board in a system during system operation without causing
undesirable effects to the running system bus or the board that is inserted into the
system.
The hot-socketing feature removes some of the difficulties that you encounter when
you use Cyclone III device family on a PCB that contains a mixture of 3.0, 2.5, 1.8, 1.5,
and 1.2 V devices. With the hot-socketing feature of Cyclone III device family, you no
longer need to ensure a proper power up sequence for each device on the board.
Cyclone III device family hot-socketing feature provides:

■
This chapter also describes the power-on reset (POR) circuitry in Cyclone III device
family. The POR circuitry keeps the devices in the reset state until the power supplies
are in operating range.
This chapter contains the following sections:

Cyclone III device family is a hot-socketing compliant without the need for any
external components or special design requirements. Hot-socketing support in
Cyclone III device family has the following advantages:
■
■
You can drive signals into I/O pins, dedicated input pins, and dedicated clock pins of
Cyclone III device family before or during power-up or power down without
damaging the device. The Cyclone III device family supports any power-up or
power down sequence (V

You can drive the device before power-up without damaging the device.
I/O pins remain tristated during power-up. The device does not drive out before
or during power-up, therefore not affecting other buses in operation.
