Electrical Characteristics
3.3
Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not
guaranteed. Stress beyond the limits specified in Table 3 may affect device reliability or cause permanent
damage to the device. For functional operating conditions, refer to the remaining tables in this chapter.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused
inputs are tied to an appropriate logic voltage level (for instance, V SS or V DD ) or the programmable pull-up
resistor associated with the pin is enabled.

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 DD ) and negative (V SS ) clamp voltages, then use the larger of the two
resistance values.
2 All functional non-supply pins are internally clamped to V
clamped to V SS only.
SS and V DD except the RESET/V PP pin which is internally
3 Power supply must maintain regulation within operating V
DD range during instantaneous and operating maximum
current conditions. If positive injection current (V In > V DD ) is greater than I DD , the injection current may flow out of V DD
and could result in external power supply going out of regulation. Ensure external V DD load will shunt current greater
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.

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. In order to take P I/O into account in power calculations, determine the difference between
actual pin voltage and V SS or V DD 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 V SS or V DD will be very
small.
