NOTE:
Instead of specifying ambient temperature all parameters are specified for the more
meaningful silicon junction temperature. For power dissipation calculations refer
to
Section A.1.8 Power Dissipation and Thermal Characteristics
.
A.1.8 Power Dissipation and Thermal Characteristics
Power dissipation and thermal characteristics are closely related. The user must assure that the maximum
operating junction temperature is not exceeded. The average chip-junction temperature (T
J
) in
°
C can be
obtained from:
The total power dissipation can be calculated from:
Two cases with internal voltage regulator enabled and disabled must be considered:

NOTES
:
1. The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The
given operating range applies when this regulator is disabled and the device is powered from an external source.
2. Some blocks e.g. ATD (conversion) and NVMs (program/erase) require higher bus frequencies for proper opera-
tion.
