Appendix A Electrical Characteristics
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

Input must be current limited to the value specified. To determine the value of the required
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
Power supply must maintain regulation within operating V

no system clock is present, or if the clock rate is very low which would reduce overall power
consumption.
