Description
The XC9572XL is a 3.3V CPLD targeted for high-performance, low-voltage applications in leading-edge communications and computing systems. It is comprised of four 54V18 Function Blocks, providing 1,600 usable gates with propagation delays of 5 ns. See Figure 2 for overview.

Power Estimation
Power dissipation in CPLDs can vary substantially depending on the system frequency, design application and output loading. To help reduce power dissipation, each macrocell in a XC9500XL device may be configured for low-power mode (from the default high-performance mode). In addition, unused product-terms and macrocells are automatically deactivated by the software to further conserve power. For a general estimate of ICC, the following equation may be used:
ICC(mA) = MCHS(0.175*PTHS + 0.345) + MCLP(0.052*PTLP + 0.272) + 0.04 * MCTOG(MCHS +MCLP)* f
where:
MC_HS = # macrocells in high-speed configuration
PT_HS = average number of high-speed product terms per macrocell
MC_LP = # macrocells in low power configuration
PT_LP = average number of low power product terms per macrocell
f = maximum clock frequency
MCTOG = average % of flip-flops toggling per clock (~12%)
This calculation was derived from laboratory measurements of an XC9500XL part filled with 16-bit counters and allowing a single output (the LSB) to be enabled. The actual ICC value varies with the design application and should be verified during normal system operation. Figure 1 shows the above estimation in a graphical form. For a more detailed discussion of power consumption in this device, see Xilinx application note XAPP114, “Understanding XC9500XL CPLD Power.”

Absolute Maximum Ratings⁽²⁾

Notes:
1. Maximum DC undershoot below GND must be limited to either 0.5V or 10 mA, whichever is easier to achieve. During transitions, the device pins may undershoot to –2.0 V or overshoot to +7.0V, provided this over- or undershoot lasts less than 10 ns and with the forcing current being limited to 200 mA. External I/O voltage may not exceed VCCINT by 4.0V.
2. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.
