I CC can be estimated for the ispLSI 2128VL using the following equation:
I CC = 12 + (# of PTs * 0.46) + (# of nets * max freq * 0.0029)
Where:
The I CC estimate is based on typical conditions (V CC = 2.5V, 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.
Figure 3. Typical Device Power Consumption vs fmax
Power consumption in the ispLSI 2128VL device de-
pends on two primary factors: the speed at which the
device is operating and the number of Product Terms
Power Consumption
# 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)
