DATA BOOK: Timing data applied to Commercial, Industrial, and Military devices


Keywords: timing, commercial, industrial, military, 3k, 4k, 5k

Urgency: Standard

General Description: Do the data book values apply to all devices
rated Commercial, Industrial, and Military.


The military grade part with the same speed grade as the
commercial grade part is actually faster when both parts run at the same

Xilinx states that for any given temperature grade part, we guarantee that the
device will perform according to the worst case delays indicated in the speeds
file when operated at its upper temperature limit.

A higher temperature grade part (say a military grade part) will run up to
the same speed at the the maximum military temperature limit that a lower
temperature grade (say, commercial grade) part will operate, at its lower,
maximum temperature limit. If a military grade part is operated at the
commercial temperature limit, it would be faster than the commercial grade
part at that temperature.

The Xilinx timing and simulation models are for:

Voltage: 5 volts -5% for commercial grade
5 volts -10% for industrial and military grade

Temperature: +85C junction temperature for commercial grade
+100C junction temperature for industrial grade
+125C case temperature for military grade

Output Loading: 50 pF

This has changed with the introduction of the XL parts -- the output
loading is rated at 35 pF.
