STR720 - ELECTRICAL CHARACTERISTICS
device at these or any other conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability. During overload conditions (V_IN>V_DD or V_IN<V_SS) the
voltage on pins with respect to ground (V_SS) must not exceed the values obtained by the
Absolute Maximum Ratings.
During Power-on and Power-off transients (including Standby entering/exiting phases), the
relationships between voltages applied to the device and the main V_DD-V_DD3 shall be always
respected. In particular power-on and power-off of A_VDD shall be coherent with V_DD transient,
in order to avoid undesired current injection through the on-chip protection diodes.

28.3 Electrical sensitivity
Based on two different tests (ESD and LU) using specific measurement methods, the product
is stressed in order to determine its performance in terms of electrical sensitivity.
28.3.1 Electro-Static Discharge (ESD)
Electro-Static Discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. Three models can be
simulated: Human Body Model, Machine Model and Charge Device Model.
