      The following guidelines are meant to represent worst-case
      scenarios so that they can be generally used to predict the
      upper limits of power dissipation. These guidelines are as
      follow:
      Logic Modules (m)
      Inputs Switching (n)
      Outputs Switching (p)
      First Routed Array Clock Loads (q
      1
      )

      One of the designs used to characterize the A54SX family
      was a 528 bit serial in serial out shift register. The design
      utilized 100%of the dedicated flip-flops of an A54SX16P
      device. A pattern of 0101… was clocked into the device at
      frequencies ranging from 1 MHz to 200 MHz. Shifting in a
      series of 0101… caused 50%of the flip-flops to toggle from
      low to high at every clock cycle.
      Follow the steps below to estimate power consumption. The
      values provided for the sample calculation below are for the
      shift register design above. This method for estimating
      power consumption is conservative and the actual power
      consumption of your design may be less than the estimated
      power consumption.
      The total power dissipation for the 54SX family is the sum of
      the AC power dissipation and the DC power dissipation.
