I CC can be estimated for the ispLSI and pLSI 1032E using the following equation:
I CC(mA) = 15 + (# of PTs 0.59) + (# of nets Max freq 0.0078)

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 (V
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.
