Artix-7 FPGAs Data Sheet:
DC and AC Switching Characteristics
DS181 (v1.15) September 23, 2014
Product Specification
Introduction
Artix®-7 FPGAs are available in -3, -2, -1, and -2L speed
grades, with -3 having the highest performance. The -2L
devices can operate at either of two V
CCINT
voltages, 0.9V
and 1.0V and are screened for lower maximum static power.
When operated at V
CCINT
= 1.0V, the speed specification of
a -2L device is the same as the -2 speed grade. When
operated at V
CCINT
= 0.9V, the -2L static and dynamic
power is reduced.
Artix-7 FPGA DC and AC characteristics are specified in
commercial, extended, industrial, expanded (-1Q), and
military (-1M) temperature ranges. Except the operating
temperature range or unless otherwise noted, all the DC
and AC electrical parameters are the same for a particular
speed grade (that is, the timing characteristics of a -1M
speed grade military device are the same as for a -1C
speed grade commercial device). However, only selected
speed grades and/or devices are available in each
temperature range. For example, -1M is only available in the
defense-grade Artix-7Q family and -1Q is only available in
XA Artix-7 FPGAs.
All supply voltage and junction temperature specifications
are representative of worst-case conditions. The
parameters included are common to popular designs and
typical applications.

Stresses beyond those listed under Absolute Maximum Ratings might 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 might affect device reliability.
The lower absolute voltage specification always applies.
For I/O operation, refer to
UG471:
7 Series FPGAs SelectIO Resources User Guide.
The maximum limit applies to DC signals. For maximum undershoot and overshoot AC specifications, see
Table 4.
See
Table 9
for TMDS_33 specifications.
For soldering guidelines and thermal considerations, see

All voltages are relative to ground.
For the design of the power distribution system consult
UG483,
7 Series FPGAs PCB Design and Pin Planning Guide.
If V
CCINT
and V
CCBRAM
are operating at the same voltage, V
CCINT
and V
CCBRAM
should be connected to the same supply.
Configuration data is retained even if V
CCO
drops to 0V.
Includes V
CCO
of 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V at ±5%.
The lower absolute voltage specification always applies.
See
Table 9
for TMDS_33 specifications.
A total of 200 mA per bank should not be exceeded.
V
CCBATT
is required only when using bitstream encryption. If battery is not used, connect V
CCBATT
to either ground or V
CCAUX
.
Each voltage listed requires the filter circuit described in
