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.

Stresses beyond those listed under Absolute 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 Ratings conditions for extended periods of time adversely affects device reliability.
As a rule, the V
handle overshoot/undershoot as well as achieve PCI compliance. Refer to the following application notes: "Virtex™-II Pro and Spartan-3
3.3V PCI Reference Design" (XAPP653) and "Using 3.3V I/O Guidelines in a Virtex-II Pro Design" (XAPP659).
Each of the User I/O and Dual-Purpose pins is associated with one of the four banks’ V
internal diode junctions that exist between these pins and their associated V
to determine the max limit. When V

All Dedicated pins (PROG_B, DONE, TCK, TDI, TDO, and TMS) draw power from the V

Advance Product Specification
All parameter limits are representative of worst-case supply
voltage and junction temperature conditions. The following
applies unless otherwise noted: The parameter values
published in this module apply to all Spartan™-3E
devices. AC and DC characteristics are specified using
the same numbers for both commercial and industrial
grades.
If a particular Spartan-3E FPGA differs in functional
behavior or electrical characteristic from this data
sheet, those differences are described in a separate
errata document. The errata documents for Spartan-3E
FPGAs are living documents and are available
