Power Consumption
Power consumption in the ispLSI 8840 device depends
on two primary factors: the speed at which the device is
operating and the number of product terms used. The
product terms have a fuse-selectable speed/power
tradeoff setting. Each group of four product terms has a
single speed/power tradeoff control fuse that acts on the
complete group of four. The fast

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.
ICC can be estimated for the ispLSI 8840 using the following equation:
ICC = 48.0 + (# of Turbo PTs * 0.346) + (# of Non-Turbo PTs * 0.165) + (# of Macrocells Used * fmax * AF * 0.049)
# of Turbo PTs = Number of Turbo Product Terms Used in Design
# of Non-Turbo PTs = Number of Non-Turbo Product Terms Used in Design
fmax = Maximum Operating Frequency
Average Macrocell Toggle Frequency
AF (Activity Factor) =
Note: An Activity Factor of 1.0 means all macrocell registers toggle at Fmax. An Activity Factor of 0.5 means the
average macrocell registers toggle at half of fmax.

operates product terms at their normal full power con-
sumption. For portions of the logic that can tolerate
longer propagation delays, selecting the slower

setting will significantly reduce the power
dissipation for these product terms. Figure 10 shows the
relationship between power and operating speed.
