This chapter describes the electric characteristics, switching characteristics, and I/O
timing for Cyclone
The following sections provide information about the absolute maximum ratings,
recommended operating conditions, DC characteristics, and other specifications for
Cyclone III LS devices.
When Cyclone III LS devices are implemented in a system, they are rated according to
a set of defined parameters. To maintain the highest possible performance and
reliability of Cyclone III LS devices, you must consider the operating requirements in
this chapter. Cyclone III LS devices are offered in commercial and industrial grades.
Commercial devices are offered in –7 (fastest) and –8 speed grades. Industrial devices
are offered only in –7 speed grade.
In this chapter, a prefix associated with the operating temperature range is attached to
the speed grades—commercial with a “C” prefix; industrial with an “I” prefix. For
example, commercial devices are described as C7 and C8 per respective speed grades.
Industrial devices are described as I7.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for
Cyclone III LS devices. The values are based on experiments conducted with the
device and theoretical modeling of breakdown and damage mechanisms. The
functional operation of the device is not implied at these conditions.
absolute maximum ratings for Cyclone III LS devices.
Conditions beyond those listed in
device. Additionally, device operation at the absolute maximum ratings for extended
periods of time may have adverse effects on the device. All parameters representing
voltages are measured with respect to ground.
