XC4000 XLA Specification Information
Definition of Terms
In the following tables, some specifications may be designated as Advance or Preliminary. These terms are defined as
follows:
Advance:
Initial estimates based on simulation and/or extrapolation from other speed grades, devices, or families.
Values are subject to change. Use as estimates, not for production.
Preliminary:
Based on preliminary characterization. Further changes are not expected.
Unmarked:
Specifications not identified as either Advance or Preliminary are to be considered final.
All specifications are subject to change without notice.
Additional Specifications
Except for pin-to-pin input and output parameters, the AC parameter delay specifications included in this document are
derived from measuring internal test patterns. All specifications are representative of worst-case supply voltage and junction
temperature conditions. The parameters included are common to popular designs and typical applications.

Notes: 1. Maximum DC overshoot or undershoot above V
cc
or below GND must be limited to either 0.5 V or 10 mA, whichever is
easier to achieve. During transitions, the device pins may undershoot to -2.0 V or overshoot to + 7.0 V, provided this over-
or undershoot lasts less than 10 ns and with the forcing current being limited to 200 mA.
2. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under
Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time may
affect device reliability.
