    Power consumption calculation for CY7C028V

      Hi all,

       

      How calculation Power requirement both static and dynamic for a DP SRAM

       

      CY7C028V

       

      Regards,

          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.
