Power Consumption
Power consumption in the ispLSI 1024EA device de-
pends 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.
0127/1024EA
Icc can be estimated for the ispLSI 1024EA using the following equation:
Icc = 17mA + (# of PTs * .726) + (# of nets * Max Freq * .0043)
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 four 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.
