ICC can be estimated for the ispLSI 1048E using the following equation:
ICC = 20 + (# of PTs * 0.42) + (# of nets * Max. freq * 0.010)
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
The ICC estimate is based on typical conditions (VCC = 5.0V, room temperature) and an assumption of 4 GLB loads on
average exists. These values are for estimates only. Since the value of ICC is sensitive to operating conditions and the
program in the device, the actual ICC should be verified.

Power Consumption
Power consumption in the ispLSI 1048E device depends
on two primary factors: the speed at which the device is
operating and the number of Product Terms used.
Figure 3 shows the relationship between power and
operating speed.
