• Manufacturer: Lattice Semiconductor

Power consumption in the ispLSI 2032 and 2032A de-
vices depends on two primary factors: the speed at which
the device is operating and the number of Product Terms
Figure 4. Typical Device Power Consumption vs fmax
I CC can be estimated for the ispLSI 2032/A using the following equation:
For 2032/A -150, -180: I CC (mA) = 30 + (# of PTs * 0.46) + (# of nets * Max freq * 0.012)
For 2032/A -135, -110, -80: I CC (mA) = 21 + (# of PTs * 0.30) + (# of nets * Max freq * 0.012)
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
# 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)
