Power consumption in the ispLSI 3448 device depends
on two primary factors: the speed at which the device is
operating and the number of product terms used.
Figure 3. Typical Device Power Consumption vs fmax
I CC can be estimated for the ispLSI 3448 using the following equation:
I CC = 60 + (# of PTs * 0.46) + (# of nets * Max. freq * 0.01) 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
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.
