INTERNAL POWER DISSIPATION (5 V)

These specifications apply to the internal power portion of VDD

only. For a complete discussion of the code used to measure

power dissipation, see the technical note “SHARC Power Dissi-

pation Measurements.”

Specifications are based on the operating scenarios.

To estimate power consumption for a specific application, use

the following equation where % is the amount of time your pro-

gram spends in that state:

%PEAK IDDINPEAK +%HIGH IDDINHIGH +%LOW IDDINLOW +

%IDLE IDDIDLE = Power Consumption

1 The test program used to measure IDDINPEAK represents worst case processor operation and is not sustainable under normal application conditions. Actual internal power

measurements made using typical applications are less than specified.

2 IDDINHIGH is a composite average based on a range of high activity code. IDDINLOW is a composite average based on a range of low activity code.

3 Idle denotes ADSP-2106x state during execution of IDLE instruction.
