8 / 11 page Specifications ispLSI 2128E 8 Power Consumption Power consumption in the ispLSI 2128E device depends on two primary factors: the speed at which the device is operating and the number of Product Terms used. Figure 3 shows the relationship between power and operating speed. Figure 3. Typical Device Power Consumption vs fmax 0127/2128E ICC can be estimated for the ispLSI 2128E using the following equation: ICC = 27 + (# of PTs * 0.55) + (# of nets * max freq * 0.0058) 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 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. 100 200 300 350 400 450 500 0 20 40 60 80 100 120 140 160 180 fmax (MHz) Notes: Configuration of eight 16-bit counters Typical current at 5V, 25 ° C 250 150 ispLSI 2128E |
