• Description: In-system Programmable High Density Pld
• Manufacturer: Lattice Semiconductor Corp.

Power consumption in the ispLSI 2064 and 2064A 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 2064/A using the following equation:
I CC (mA) = 38 + (# of PTs * 0.33) + (# of nets * Max freq * 0.007)
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)
