Electrical Characteristics
This section contains electrical specification tables and reference timing diagrams for the microcontroller unit, including
detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications.
NOTE
The parameters specified in this data sheet supersede any values found in the module
specifications.

Maximum Ratings
Table 4. Absolute Maximum Ratings1, 2
1 Functional operating conditions are given in DC Electrical Specifications. Absolute Maximum Ratings
are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond
those listed may affect device reliability or cause permanent damage to the device.
2 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 (VSS or VDD).

use the larger of the two values.

4 All functional non-supply pins are internally clamped to V
SS and VDD.
5 The power supply must maintain regulation within operating V
DD 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 the external power supply going out of
regulation. Ensure that the external VDD load shunts current greater than maximum injection current.
This is the greatest risk when the MCU is not consuming power (e.g., no clock).
