Description
The XC95108 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 2,400 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 XC95108 by con-
figuring macrocells to standard or low-power modes of
operation. Unused macrocells are turned off to minimize
power dissipation.
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)
Figure 1 shows a typical calculation for the XC95108
device.
