Power Consumption
setting operates product terms at their normal full power
consumption. For portions of the logic that can tolerate
longer propagation delays, selecting the slower “l(fā)ow-
power” setting will reduce the power dissipation for these
product terms. Figure 10 shows the relationship between
power and operating frequency.
Power consumption in the ispLSI 5256VE device de-
pends 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 five product terms
has a single speed/power tradeoff control fuse that acts
on the complete group of five. The fast “high-speed”

ICC can be estimated for the ispLSI 5256VE using the following equation:
High Speed Mode: ICC = 21 + (# of PTs * 0.313) + (# of nets * Fmax * 0.00282)
Low Power Mode: ICC = 21 + (# of PTs * 0.258) + (# of nets * Fmax * 0.00282)
# of PTs = Number of Product Terms used in design
# of nets = Number of Signals used in device
Fmax = Highest Clock Frequency to the device
The ICC estimate is based on typical conditions (VCC = 3.3V, room temperature) and an assumption of one GLB load
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.
