1. Cyclone III Device Datasheet

July 2012

CIII52001-3.5

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.

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.
