Power consumption in the ispLSI 1016EA device de-
pends on two primary factors: the speed at which the
device is operating and the number of Product Terms
Figure 4. Typical Device Power Consumption vs fmax
I CC can be estimated for the ispLSI 1016EA using the following equation:
I CC (mA) = 23 + (# of PTs * 0.52) + (# of nets * max freq * 0.004)
Where:
The I CC estimate is based on typical conditions (V CC = 5.0V, room temperature) and an assumption of four GLB loads
on average exists and the device is filled with four 16-bit counters. These values are for estimates only. Since the
value of I CC is sensitive to operating conditions and the program in the device, the actual I CC should be verified.
Maximum GRP Delay vs GLB Loads
Power Consumption
# 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)
