Power Consumption
Power consumption in the ispLSI 2032 and 2032A de- used. Figure 4 shows the relationship between power
vices depends on two primary factors: the speed at which and operating speed.
the device is operating and the number of Product Terms

03 ICC can be estimated for the ispLSI 2032/A using the following equation:
2 For 2032/A -150, -180: ICC(mA) = 30 + (# of PTs * 0.46) + (# of nets * Max freq * 0.012)
I For 2032/A -135, -110, -80: ICC(mA) = 21 + (# of PTs * 0.30) + (# of nets * Max freq * 0.012)
LS Where:
# of PTs = Number of Product Terms used in design
p # of nets = Number of Signals used in device
is Max freq = Highest Clock Frequency to the device (in MHz)
The ICC estimate is based on typical conditions (VCC = 5.0V, room temperature) and an assumption of two GLB loads
E on average exists. These values are for estimates only. Since the value of ICC is sensitive to operating conditions
S and the program in the device, the actual ICC should be verified.
