Preliminary Electrical Specifications
17.3 Absolute Maximum Ratings
Maximum ratings are the extreme limits to which the MCU can be
exposed without permanently damaging it.
NOTE: This device is not guaranteed to operate properly at the maximum
ratings. Refer to 17.7 3.0-Volt DC Electrical Characteristics
Excluding UHF Module for guaranteed operating conditions.

NOTE: This device contains circuitry to protect the inputs against damage due
to high static voltages or electric fields; however, it is advised that normal
precautions be taken to avoid application of any voltage higher than
maximum-rated voltages to this high-impedance circuit. For proper
operation, it is recommended that V and V
be constrained to the
