Electrical Specifications
14.1 Introduction
This section contains the electrical and timing specifications.
14.2 Maximum Ratings
Maximum ratings are the extreme limits to which the MCU can be exposed without permanently damaging
it.
The MCU contains circuitry to protect the inputs against damage from high static voltages; however, do
not apply voltages higher than those shown in the table below. Keep V_In and V_Out within the range
V_SS ≤ (V_In or V_Out) ≤ V_DD. Connect unused inputs to the appropriate voltage level, either V_SS or V_DD.
