Compared to the rest of the device, the embedded array
consumes a negligible amount of power. Therefore, the
embedded array can be ignored when calculating supply
current.
The I

Maximum operating frequency in MHz
Total number of logic cells used in the device
Average percent of logic cells toggling at each clock

This value is preliminary. For the most up-to-date information, contact
Altera Applications.
This calculation provides an I
CC
estimate based on typical conditions
with no output load. The actual I
CC
should be verified during
operation because this measurement is sensitive to the actual pattern
in the device and the environmental operating conditions.
