A.1.8
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
obtained from:
The total power dissipation can be calculated from:

Operating Junction Temperature Range
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.
Some blocks e.g. ATD (conversion) and NVMs (program/erase) require higher bus frequencies for proper operation.
