Appendix A Electrical Characteristics
A.1
This section contains electrical and timing specifications.
A.2
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not
guaranteed. Stress beyond the limits specified in
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 V
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
voltages, then use the larger of the two resistance values.
All functional non-supply pins are internally clamped to 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.
