Many operating conditions can affect power dissipation. System
designers should refer to Estimating Power for ADSP-BF561
Blackfin Processors (EE-293) on the Analog Devices website
( www.analog.com )—use site search on “EE-293.” This docu-
ment provides detailed information for optimizing your design
for lowest power.
See the ADSP-BF561 Blackfin Processor Hardware Reference
Manual for definitions of the various operating modes and for
instructions on how to minimize system power.

The time t ENA _ MEASURED is the interval, from when the reference sig-
nal switches, to when the output voltage reaches V TRIP (high) or
V TRIP (low). V TRIP (high) is 2.0 V and V TRIP (low) is 1.0 V for V DDEXT
(nominal) = 2.5 V/3.3 V. Time t TRIP is the interval from when the
output starts driving to when the output reaches the V TRIP (high)
or V TRIP (low) trip voltage.
Time t ENA is calculated as shown in the equation:
t ENA = t ENA_MEASURED – t TRIP

If multiple pins (such as the data bus) are enabled, the measure-

difference between t DIS _ MEASURED and t DECAY as shown on the left side
