Description
The XC9572XL is a 3.3V CPLD targeted for high-perfor-
mance, low-voltage applications in leading-edge communi-
cations 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 depend-
ing 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 addi-
tion, unused product-terms and macrocells are automati-
cally deactivated by the software to further conserve power.
For a general estimate of I
CC
, the following equation may be
used:
I
CC
(mA) = MC
HS
(0.175*PT
HS
+ 0.345) + MC
LP
(0.052*PT
LP
+ 0.272) + 0.04 * MC
TOG
(MC
HS
+MC
LP
)* 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 I
CC
value varies with the design application and should be veri-
fied 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
