ENVIRONMENTAL CONDITIONS
Thermal Characteristics
The ADSP-21061 is available in 240-lead thermally enhanced
MQFP package. The top surface of the thermally enhanced
MQFP contains a metal slug from which most of the die heat is
dissipated. The slug is flush with the top surface of the package.
Note that the metal slug is internally connected to GND
through the device substrate.
The ADSP-21061L is available in 240-lead MQFP and 225-ball
plastic BGA packages.
All packages are specified for a case temperature (T
ensure that the T
flow source may be used. A heat sink should be attached with a
thermal adhesive.

PD =Power dissipation in W (this value depends upon the spe-
cific application; a method for calculating PD is shown under
Power Dissipation).
