1. Cyclone III Device Data Sheet
CIII52001-3.3
This chapter describes the electric characteristics, switching characteristics, and I/O
timing for Cyclone^® III devices. A glossary is also included for your reference.
Electrical Characteristics
The following sections provide information about the absolute maximum ratings,
recommended operating conditions, DC characteristics, and other specifications for
Cyclone III devices.
Operating Conditions
When Cyclone III 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 devices, system designers must consider the operating
requirements in this document. Cyclone III devices are offered in commercial,
industrial, and automotive grades. Commercial devices are offered in –6 (fastest), –7,
and –8 speed grades. Industrial and automotive devices are offered only in –7 speed
grade.
1 In this chapter, a prefix associated with the operating temperature range is attached to
the speed grades; commercial with “C” prefix, industrial with “I” prefix, and
automotive with “A” prefix. Commercial devices are therefore indicated as C6, C7,
and C8 per respective speed grades. Industrial and automotive devices are indicated
as I7 and A7, respectively.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for Cyclone III
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. Table 1–1 lists the absolute
maximum ratings for Cyclone III devices.
1 Conditions beyond those listed in Table 1–1 cause permanent damage to the device.
Additionally, device operation at the absolute maximum ratings for extended periods
of time has adverse effects on the device.
