Total Power Dissipation
Total power dissipation has two components:
1. Static, including leakage current
2. Dynamic, due to transistor switching characteristics
Many operating conditions can also affect power dissipation,
including temperature, voltage, operating frequency, and pro-
shows the current dissipation for internal circuitry (VDDINT).
IDDDEEPSLEEP specifies static power dissipation as a function of
voltage (VDDINT) and temperature (see Table 18), and IDDINT
specifies the total power specification for the listed test condi-
tions, including the dynamic component as a function of voltage
(VDDINT) and frequency (Table 19).
There are two parts to the dynamic component. The first part is
due to transistor switching in the core clock (CCLK) domain.
This part is subject to an Activity Scaling Factor (ASF) which
represents application code running on the processor core and
L1 memories (Table 17).
The ASF is combined with the CCLK Frequency and VDDINT
dependent data in Table 19 to calculate this part. The second
part is due to transistor switching in the system clock (SCLK)
domain, which is included in the IDDINT specification equation.

1 See Estimating Power for ASDP-BF534/BF536/BF537 Blackfin Processors
(EE-297). The power vector information also applies to the ADSP-BF50x
processors.
