For a general estimate of I
CC
, the following equation may be
used:
P
TOTAL
= P
INT
+ P
IO
= I
CCINT
x V
CCINT
+ P
IO
Separating internal and I/O power here is convenient
because XC9500XV CPLDs also separate the correspond-
ing power pins. P
IO
is a strong function of the load capaci-
tance driven, so it is handled by I = CVf. I
CCINT
is another
situation that reflects the actual design considered and the
internal switching speeds. An estimation expression for
I
CCINT
(taken from simulation) is:

frequently a good estimate
This calculation was derived from laboratory measurements
of an XC9500XV 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.

Description
The XC9536XV is a 2.5V CPLD targeted for high-perfor-
mance, low-voltage applications in leading-edge communi-
cations and computing systems. It is comprised of two
54V18 Function Blocks, providing 800 usable gates with
propagation delays of 5 ns. See
for architecture

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.
