Power
Consumption
The supply power (P) for FLEX 8000 devices can be calculated with the
following equation:
P = PINT + PIO = [(ICCSTANDBY + ICCACTIVE) × VCC] + PIO
Typical ICCSTANDBY values are shown as ICC0 in Table 11 on page 28 and
Table 15 on page 30. The PIO value, which depends on the device output
load characteristics and switching frequency, can be calculated using the
Devices). The ICCACTIVE value depends on the switching frequency and
the application logic. This value can be calculated based on the amount of
current that each LE typically consumes.
The following equation shows the general formula for calculating
ICCACTIVE:
The parameters in this equation are shown below:
fMAX
= Maximum operating frequency in MHz
N
= Total number of logic cells used in the device
togLC = Average percentage of logic cells toggling at each clock
K
= Constant, shown in Table 50
This calculation provides an ICC estimate based on typical conditions
with no output load. The actual ICC value should be verified during
operation because this measurement is sensitive to the actual pattern in
the device and the environmental operating conditions.
Figure 20 shows the relationship between ICC and operating frequency
for several LE utilization values.
