The XC95108 is a high-performance CPLD that provides advanced in-system programming and testing capabilities for general-purpose logic integration. It consists of eight 36V18 functional modules that provide 2,400 usable gates with a propagation delay of 7.5 ns. For an architecture overview, see the figure below
Power Management
Power dissipation can be reduced in the XC95108 by configuring 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: ICC (mA) = MCHP (1.7) + MCLP (0.9) + MC (0.006 mA/MHz) f Where:
● MCHP = Macrocells in high-performance mode
● MCLP = Macrocells in low-power mode
● MC = Total number of macrocells used
● f = Clock frequency (MHz)
The following figure shows a typical computing appliance for the XC95108.
