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 PI/O into account in power calculations, determine the difference between actual pin

voltage and VSS or VDD 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 VSS or VDD will be very small.

Single-layer board

2 Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board) temperature,

ambient temperature, air flow, power dissipation of other components on the board, and board thermal resistance.
