Separating internal and I/O power here is convenient
because XC9500XV CPLDs also separate the correspond-
ing power pins. PIO is a strong function of the load capaci-
tance driven, so it is handled by I = CVf. ICCINT is another
situation that reflects the actual design considered and the
internal switching speeds. An estimation expression for

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 ICC
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
application note XAPP361, “Planning for High Speed
XC9500XV Designs.”

Description

200 MHz
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 Figure 2 for architecture
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 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.
