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.
3.
Negative injection disturbs the analog performance of the device. In particular, it induces leakage currents
throughout the device including the analog inputs. To avoid undesirable effects on the analog functions,
care must be taken:
- Analog input pins must have a negative injection less than 0.8 mA (assuming that the impedance of the
analog voltage is lower than the specified limits)
- Pure digital pins must have a negative injection less than 1.6 mA. In addition, it is recommended to inject
the current as far as possible from the analog input pins.

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
characterisation with
