Power Consumption

Power consumption in the ispLSI 2032VE 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 2032VE using the following equation:

For ispLSI 2032VE-225: ICC(mA) = 4.5 + (# of PTs * 1.29) + (# of nets * Max freq * 0.0068)

For ispLSI 2032VE-180 and slower: ICC(mA) = 4.5 + (# of PTs * 1.05) + (# of nets * Max freq * 0.0068)

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 = 3.3V, 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.
