Product Specification
Operating current for each design can be approximated for
specific operating conditions using the following equation:
I
CC
(mA) =
MC
HP
(1.7) + MC
LP
(0.9) + MC (0.006 mA/MHz) f
Where:
MC
HP
= Macrocells in high-performance mode
MC
LP
= Macrocells in low-power mode
MC = Total number of macrocells used
f = Clock frequency (MHz)
shows a typical calculation for the XC95144
device.

Description
The XC95144 is a high-performance CPLD providing
advanced in-system programming and test capabilities for
general purpose logic integration. It is comprised of eight
36V18 Function Blocks, providing 3,200 usable gates with
propagation delays of 7.5 ns. See
for the architec-
ture overview.

Power Management
Power dissipation can be reduced in the XC95144 by con-
figuring macrocells to standard or low-power modes of
operation. Unused macrocells are turned off to minimize
power dissipation.
