DC Electrical Characteristics
In this section, specifications may be designated as
Advance, Preliminary, or Production. These terms are
defined as follows:
Advance: Initial estimates are based on simulation, early
characterization, and/or extrapolation from the characteris-
tics of other families. Values are subject to change. Use as
estimates, not for production.
Preliminary: Based on characterization. Further changes
are not expected.
Production: These specifications are approved once the
silicon has been characterized over numerous production
lots. Parameter values are considered stable with no future
changes expected.

Input voltages outside the -0.5V to V
diode rating is met and no more than 100 pins exceed the range simultaneously. Prolonged exposure to such current may compromise
device reliability. A sustained current of 10 mA will not compromise device reliability.

Product Specification
All parameter limits are representative of worst-case supply
voltage and junction temperature conditions. Unless other-
wise noted, the published parameter values apply to all
Spartan®-3E devices. AC and DC characteristics are
specified using the same numbers for both commercial
and industrial grades.
Absolute Maximum Ratings
Stresses beyond those listed under
Maximum Ratings may cause permanent damage to the
device. These are stress ratings only; functional operation
of the device at these or any other conditions beyond those
listed under the Recommended Operating Conditions is not
implied. Exposure to absolute maximum conditions for
extended periods of time adversely affects device reliability.
