Power dissipation can be reduced in the XC9572 by config-
uring macrocells to standard or low-power modes of opera-
tion. Unused macrocells are turned off to minimize power
dissipation.

Description
(65)
The XC9572 is a high-performance CPLD providing
advanced in-system programming and test capabilities for
general purpose logic integration. It is comprised of four
36V18 Function Blocks, providing 1,600 usable gates with
propagation delays of 7.5 ns. See Figure 2 for the architec-
ture overview.
