• Pinout and Description
The XC9536XL is a 3.3V CPLD primarily intended for high-performance, low-voltage applications in high-end communications and computing systems. It consists of a two-part 54V18 function block that provides 800 usable gates with a propagation delay of 5ns.
Overview.
power estimation
The power consumption of cpld varies greatly with system frequency, design application and output.
load. To reduce power consumption, for each macrocell in the XC9500XL, the device can be configured in a low-power mode (from the default high-performance mode). In addition, the software automatically deactivates unused product terms and macrocells for further energy savings.
For a general estimate of ICC, the following equation can be used:
ICC(mA) = MCHP(0.5) + MCLP(0.3) + MC(0.0045 mA/MHz) where is F?
MCHP=macrocells in high performance (default) mode MCLP=macrocells in low power mode mc=total number of macrocells used F=clock frequency (MHz) This calculation is based on typical operating conditions using 16 in each function The mode of the bit up/down counter does not output the loaded block. Actual ICC values vary along with the design application and should work properly in the system.
