5.3 Thermal specifications
5.3.1 Thermal characteristics
This section provides information about operating temperature range, power dissipation,
and package thermal resistance. Power dissipation on I/O pins is usually small compared
to the power dissipation in on-chip logic and voltage regulator circuits, and it is user-
determined rather than being controlled by the MCU design. To take P_I/O into account in
power calculations, determine the difference between actual pin voltage and V_SS or V_DD
and multiply by the pin current for each I/O pin. Except in cases of unusually high pin
current (heavy loads), the difference between pin voltage and V_SS or V_DD will be very
small.
