Specifications ispLSI 2064VL

Power Consumption

Power consumption in the ispLSI 2064VL device de-

pends on two primary factors: the speed at which the

device is operating and the number of Product Terms

used. Figure 3 shows the relationship between power

and operating speed.

ICC can be estimated for the ispLSI 2064VL using the following equation:

ICC(mA) = 8 + (# of PTs * 0.42) + (# of Nets * Max. Freq. * 0.0025)

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 (in MHz)

The ICC estimate is based on typical conditions (VCC = 2.5V, room temperature) and an assumption of two GLB

loads on average exists. These values are for estimates only. Since the value of ICC is sensitive to operating

conditions and the program in the device, the actual ICC should be verified.
