Hi,

Static Power or Core Power = Vcc X Icc

Dynamic Power or I/O Switching Power = a × f × CL × V 2 x (number of I/Os that are switching),

where:

a is the activity factor, or the ratio of frequency at which outputs toggle to the clock frequency

= 0.5 for single data rate devices like Std Sync, NoBL™- SRAMs;

= 1 for double data rate devices (such as DDR/QDR™ SRAMs)

f = operating frequency

CL = external load capacitance

V is output voltage swing,

For example,

= Vddq for unterminated load

= Vddq/2 for a terminated load with pull-up termination.

We also have an app note on this. Kindly go through it once and let us for any queries.
