I CC can be estimated for the ispLSI 2064E using the following equation:
I CC (mA) = 7 + (# of PTs * 0.75) + (# of nets * Max freq * 0.004)
Where:
The I CC estimate is based on typical conditions (V CC = 5.0V, room temperature) and an assumption of two GLB loads on
average exists. These values are for estimates only. Since the value of I CC is sensitive to operating conditions and the
program in the device, the actual I CC should be verified.
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.
