Power Consumption
Power consumption in the ispLSI 2128E 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.

0127/2128E
ICC can be estimated for the ispLSI 2128E using the following equation:
ICC = 27 + (# of PTs * 0.55) + (# of nets * max freq * 0.0058)
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 ICC estimate is based on typical conditions (VCC = 5.0V, room temperature) and an assumption of two 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.
