describe
Xc95144xl is a 3.3vcpld control system, which can be used in high-performance and low-voltage applications in cutting-edge communication and computing systems. It consists of eight 54v18 function blocks, provides 3200 available gates, and the propagation delay is 5ns.
Power estimation
The power consumption of CPLD can vary greatly according to the system frequency, design application and output load. To help reduce power consumption, each macrocell in the xc9500xl device can be configured in low-power mode (starting from the default high-performance mode). In addition, unused product terms and macro units are automatically deactivated by the software to further save power. For the general estimation of ICC, the following formula can be used:
ICC(mA)=MCHS(0.175*PTHS+0.345)+MCLP(0.052*PTLP+0.272)+0.04*MCTOG(MCHS+MCLP)*f
Where: mchs = # high-speed cells in high-speed configuration PTHs = average number of high-speed product terms MCLP = # macro cells in low-power configuration PTLP = average low-power product terms f = maximum clock frequency mctog = average% switching per clock (~ 12%)
This calculation comes from laboratory measurements of xc9500xl components populated with 16 bit counters and allows a single output (LSB) to be enabled. The actual ICC value varies with the design application and should be verified during normal system operation.
