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.
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-3
devices.
AC and DC characteristics are specified using
the same numbers for both commercial and industrial
grades.
All parameters representing voltages are mea-
sured with respect to GND.
Some specifications list different values for one or more die
revisions. All presently available Spartan-3 devices are
classified as revision 0. Future updates to this module will
introduce further die revisions as needed.
If a particular Spartan-3 FPGA differs in functional behavior
or electrical characteristic from this data sheet, those differ-
ences are described in a separate errata document. The
errata documents for Spartan-3 FPGAs are living docu-
ments and are available
online
.
All specifications in this module also apply to the
Spartan-3L family (the low-power version of the Spartan-3
family). Refer to the Spartan-3L datasheet (
DS313
) for any
differences.
