Power
Consumption
Altera Corporation
The supply power (P) for FLEX 8000 devices can be calculated with the
following equation:
P = P
Typical I
Table 15 on page 30. The P
load characteristics and switching frequency, can be calculated using the
guidelines given in
Devices). The I
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
I
