Electrical Specifications
19.3 Functional Operating Range
19.4 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
voltage and V
pin current (heavy loads), the difference between pin voltage and V
