Specifications ispLSI 2032/A

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

used. Figure 4 shows the relationship between power

and operating speed.

0127A/2032A

ICC can be estimated for the ispLSI 2032/A using the following equation:

For 2032/A -150, -180: ICC(mA) = 30 + (# of PTs * 0.46) + (# of nets * Max freq * 0.012)

For 2032/A -135, -110, -80: ICC(mA) = 21 + (# of PTs * 0.30) + (# of nets * Max freq * 0.012)

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 = 5.0V, 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.
