Power Consumption
used. Figure 4 shows the relationship between power
and operating speed.
Power consumption in the ispLSI 2032 and 2032A de-
vices depends on two primary factors: the speed at which
the device is operating and the number of Product Terms

I
can be estimated for the ispLSI 2032/A using the following equation:
CC
For 2032/A -150, -180: I (mA) = 30 + (# of PTs 0.46) + (# of nets Max freq 0.012)
*
*
*
CC
For 2032/A -135, -110, -80: I (mA)= 21 + (# of PTs 0.30) + (# of nets Max freq 0.012)
*
*
*
CC
Where:
# of PTs = Number of Product Terms used in design
# of nets = Number of Signals used in device
Max freq = Highest Clock Frequency to the device (in MHz)
The I
CC
estimate is based on typical conditions (V
= 5.0V, room temperature) and an assumption of two GLB loads
CC
on average exists. These values are for estimates only. Since the value of I
is sensitive to operating conditions
CC
and the program in the device, the actual I
should be verified.
