Total Power Dissipation
Total power dissipation has two components:
1. Internal power consumption
2. External power consumption
Internal power consumption also comprises two components:
1. Static, due to leakage current. Table 12 shows the static cur-
rent consumption (IDD-STATIC) as a function of junction
temperature (TJ) and core voltage (VDD_INT).
2. Dynamic (IDD-DYNAMC), due to transistor switching char-
acteristics and activity level of the processor. The activity
level is reflected by the Activity Scaling Factor (ASF), which
represents application code running on the processor core
and having various levels of peripheral and external port
activity (Table 11). Dynamic current consumption is calcu-
lated by scaling the specific application by the ASF and
using baseline dynamic current consumption as a
reference.
External power consumption is due to the switching activity of
the external pins.
The ASF is combined with the CCLK frequency and VDD_INT
dependent data in Table 13 to calculate this part. The second
part is due to transistor switching in the peripheral clock
(PCLK) domain, which is included in the IDD_INT specification
equation.
Table 11. Activity Scaling Factors (ASF)1
1 See Estimating Power for SHARC Processors (EE-348) for more information on
the explanation of the power vectors specific to the ASF table.
