ADSP-BF534/ADSP-BF536/ADSP-BF537
System designers should refer to Estimating Power for the
ADSP-BF534/BF536/BF537 Blackfin Processors (EE-297), which
provides detailed information for optimizing designs for lowest
power. All topics discussed in this section are described in detail
in EE-297. 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-
cessor activity. Electrical Characteristics on Page 25 shows the
current dissipation for internal circuitry (VDDINT). IDDDEEPSLEEP
specifies static power dissipation as a function of voltage
(VDDINT) and temperature (see Table 16 or Table 15), 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 18).
The dynamic component is also subject to an Activity Scaling
Factor (ASF) which represents application code running on the
processor (Table 17).
