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

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 –2.0V 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 V
CCINT
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.
3. For soldering guidelines and thermal considerations, see the
Device Packaging
information on the Xilinx website. For Pb-free
packages, see
