3.4
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.
The average chip-junction temperature (TJ) in °C can be obtained from:

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
resistance values.
All functional non-supply pins are internally clamped to V
clamped to V
Power supply must maintain regulation within operating V
current conditions. If positive injection current (V
and could result in external power supply going out of regulation. Ensure external V
than maximum injection 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.
