Power consumption in the ispLSI 2192VE device de-
pends on two primary factors: the speed at which the
device is operating and the number of Product Terms
Figure 3. Typical Device Power Consumption vs fmax
I CC can be estimated for the ispLSI 2192VE using the following equation:
I CC = 25 + (# of PTs * 0.670) + (# of nets * max freq * 0.0051)
Where:
The I CC estimate is based on typical conditions (V CC = 3.3V, 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.
