Absolute maximum ratings
Stresses above those listed as “absolute maximum ratings” may cause permanent damage
to the device. This is a stress rating only and functional operation of the device under these
conditions is not implied. Exposure to maximum rating conditions for extended periods may
affect device reliability.

1.
Directly connecting the RESET and I/O pins to VDD or VSS could damage the device if an unintentional
internal reset is generated or an unexpected change of the I/O configuration occurs (for example, due to a
corrupted program counter). To guarantee safe operation, this connection has to be done through a pull-up
or pull-down resistor (typical: 4.7k
Ω for RESET, 10kΩ for I/Os). Unused I/O pins must be tied in the same
way to VDD or VSS according to their reset configuration.

2.
IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum
cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive
injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. For true open-drain pads,
there is no positive injection current, and the corresponding VIN maximum must always be respected

When several inputs are submitted to a current injection, the maximum
ΣI
INJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on
characterization with
