1. DC and Switching Characteristics of
HardCopy III Devices
HIII53001-2.0
Electrical Characteristics
This chapter provides information about the absolute maximum ratings,
recommended operating conditions, DC electrical characteristics, and other
specifications for HardCopy^® III devices. HardCopy III devices are offered in both
commercial and industrial grades.
Operating Conditions
When HardCopy 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, you must consider the operating requirements described in this chapter.
HardCopy III devices are not speed binned like Stratix^® III devices because
HardCopy III devices are designed and built to function at a target frequency based
on timing constraints, and operate at either commercial or industrial temperatures.
Absolute Maximum Ratings
Absolute maximum ratings define the maximum operating conditions for
HardCopy 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 by these conditions. Conditions
beyond those listed in Table 1–1 can cause permanent damage to the device.
Additionally, device operation at the absolute maximum ratings for extended periods
of time can have adverse effects on the device.
