ispLSI 2064VE
Power Consumption
Power consumption in the ispLSI 2064VE device de-
pends on two primary factors: the speed at which the
device is operating and the number of Product Terms

ICC can be estimated for the ispLSI 2064VE using the following equation:
ICC(mA) = 8 + (# of PTs * 0.67) + (# of Nets * Max. Freq. * 0.0045)
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 = 3.3V, 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.
