Features

Operating Conditions

When Cyclone IV 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 IV devices, you must consider the operating requirements described in this chapter.

Cyclone IV devices are offered in commercial, industrial, extended industrial and, automotive grades. Cyclone IV E devices offer –6 (fastest), –7, –8, –8L, and –9L speed grades for commercial devices, –8L speed grades for industrial devices, and –7 speed grade for extended industrial and automotive devices. Cyclone IV GX devices offer –6 (fastest), –7, and –8 speed grades for commercial devices and –7 speed grade for industrial devices.
