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 XC9500XV 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
HP
(0.36) + MC
LP
(0.23) + MC(0.005 mA/MHz) f
Where:
MC
HP
= Macrocells in high-performance (default) mode
MC
LP
= Macrocells in low-power mode
MC = Total number of macrocells used
f = Clock frequency (MHz)
This calculation is based on typical operating conditions
using a pattern of 16-bit up/down counters in each Function
Block with no output loading. The actual I
CC
value varies
with the design application and should be verified during
normal system operation.
Figure 1
shows the above estimation in a graphical form.
