Description
The XC9536XV is a 2.5V CPLD targeted for high-performance, low-voltage applications in leading-edge communications and computing systems. It is comprised of two
54V18 Function Blocks, providing 800 usable gates with
propagation delays of 3.5 ns. See Figure 2 for architecture
overview.
Power Estimation
Power dissipation in CPLDs can vary substantially depending 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 ad dition, unused product-terms and macrocells are automatically 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) + MCLP(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.
