• Manufacturer: LATTICE [Lattice Semiconductor]

Power consumption in the ispLSI and pLSI 1032 device
depends 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 and pLSI 1032 using the following equation:
I CC = 52 + (# of PTs * 0.30) + (# of nets * Max. freq * 0.009) 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 2 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.
