EXTERNAL POWER DISSIPATION (3.3 V)
Total power dissipation has two components, one due to inter-
nal circuitry and one due to the switching of external output
drivers. Internal power dissipation is dependent on the instruc-
tion execution sequence and the data operands involved.
Internal power dissipation is calculated in the following way:
The external component of total power dissipation is caused by
the switching of output pins. Its magnitude depends on:
and is calculated by:
The load capacitance should include the processor’s package
capacitance (CIN). The switching frequency includes driving
the load high and then back low. Address and data pins can
