POWER DISSIPATION ADSP-21060LC (3.3 V)
These specifications apply to the internal power portion of VDD only. See the Power Dissipation section of this data sheet for calcula-
tion of external supply current and total supply current. For a complete discussion of the code used to measure power dissipation,
see the technical note “SHARC Power Dissipation Measurements.”
Specifications are based on the following operating scenarios:
Operation
Peak Activity (IDDINPEAK)
High Activity (IDDINHIGH)
Low Activity (IDDINLOW)
Instruction Type
Multifunction
Single Function
Instruction Fetch
Cache
Internal Memory
Core Memory Access
2 per Cycle (DM and PM)
1 per Cycle (DM)
None
Internal Memory DMA
1 per Cycle
1 per 2 Cycles
To estimate power consumption for a specific application, use the following equation where % is the amount of time your program
spends in that state:
%PEAK
× I
DDINPEAK + %HIGH
× I
DDINHIGH + %LOW
× I
DDINLOW + %IDLE
× I
DDIDLE = power consumption

NOTES
1The test program used to measure I
DDINPEAK 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.
2I
DDINHIGH is a composite average based on a range of high activity code. I DDINLOW is a composite average based on a range of low activity code.
3Idle denotes ADSP-21060LC state during execution of IDLE instruction.
