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 the following table may affect device reliability or cause
permanent damage to the device. For functional operating conditions, refer to the remaining tables in this
section.
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, either VSS or VDD).

Instantaneous maximum current
Single pin limit (applies to all port pins)1, 2, 3
1
Input must be current limited to the value specified. To determine the value of the required current-limiting resistor,
calculate resistance values for positive (VDD) and negative (VSS) clamp voltages, then use the larger of the two
resistance values.
2
All functional non-supply pins are internally clamped to VSS and VDD.
3
Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum
current conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of
VDD and could result in external power supply going out of regulation. Ensure external VDD 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).
