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 Figure 2 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.
