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 voltage regulator circuits and it is user-determined rather than being controlled by the
MCU design. In order to take P
actual pin voltage and V
unusually high pin current (heavy loads), the difference between pin voltage and V
small.

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.

Power supply must maintain regulation within operating V

current. This will be the greatest risk when the MCU is not consuming power. Examples are: if
no system clock is present, or if the clock rate is very low which would reduce overall power
consumption.
