XC73144 CMOS EPLD
Absolute Maximum Ratings
Warning : 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 Recommended Operating Conditions is not implied. Exposure to Absolute Maximum Ratings condi-
tions for extended periods of time may affect device reliability.
Recommended Operating Conditions
Power Management
The XC73144 features a power-management scheme
which permits non-speed-critical paths of a design to be
operated at reduced power. Overall power dissipation is
often reduced significantly, since, in most systems only a
few paths are speed critical.
Macrocells can individually be specified for high per-
formance or low power operation by adding attributes to
the logic schematic, or declaration statements to the
behavioral description. To minimize power dissipation,
unused Function Blocks are turned off and unused
Macrocells in used Function Blocks are configured for low
power operation.
Operating current for each design can be approximated for
specific operating conditions using the following equation:
