greatest risk when the MCU is not consuming power; e.g. if no system clock is present, or if clock rate is

very low which would reduce overall power consumption.

A.1.5 Absolute Maximum Ratings

Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima

is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of the

device.

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 (e.g., either VSS5 or VDD5).

2. The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply.

The absolute maximum ratings apply when the device is powered from an external source.
