ispLSI 2064/A
Power Consumption
Power consumption in the ispLSI 2064 and 2064A de-
vices depends 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 2064/A using the following equation:
is
pL
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 I CC should be verified.
