ispLSI 2064E
Power Consumption
Power consumption in the ispLSI 2064E device depends
on two primary factors: the speed at which the device is
operating and the number of Product Terms used.

ICC can be estimated for the ispLSI 2064E using the following equation:
ICC(mA) = 7 + (# of PTs * 0.75) + (# of nets * Max freq * 0.004)
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.
