Typical current at 3.3V, 25° C
ICC can be estimated for the ispLSI 2192VE using the following equation:
ICC = 25 + (# of PTs * 0.670) + (# of nets * max freq * 0.0051)
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.
