Appendix A Electrical Characteristics and Timing Specifications
A.4
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 it is user-determined rather than being controlled by the MCU design. In order to take

and multiply by the pin current for each I/O pin. Except in cases of unusually high pin current (heavy

current-limiting resistor, calculate resistance values for positive (V
voltages, then use the larger of the two resistance values.
All functional non-supply pins are internally clamped to V

no system clock is present, or if the clock rate is very low which would reduce overall power
consumption.
Single pin limit (applies to all port pins)
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.
