19 / 64 page  ADSP-21060/ADSP-21060L/ADSP-21062/ADSP-21062L/ADSP-21060C/ADSP-21060LC Rev. F | Page 19 of 64 | March 2008 INTERNAL POWER DISSIPATION (3.3 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 Operation Peak Activity (IDDINPEAK) High Activity (IDDINHIGH) Low Activity (IDDINLOW) Instruction Type Multifunction Multifunction Single Function Instruction Fetch Cache Internal Memory 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 1 per 2 Cycles Parameter Test Conditions Max Units IDDINPEAK Supply Current (Internal) 1 tCK = 30 ns, VDD = Max tCK = 25 ns, VDD = Max 540 600 mA mA IDDINHIGH Supply Current (Internal) 2 tCK = 30 ns, VDD = Max tCK = 25 ns, VDD = Max 425 475 mA mA IDDINLOW Supply Current (Internal) 2 tCK = 30 ns, VDD = Max tCK = 25 ns, VDD = Max 250 275 mA mA IDDIDLE Supply Current (Idle) 3 VDD = Max 180 mA 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-2106xL state during execution of IDLE instruction. |
