1. All power (VDD) and ground (VSS) lines must always be connected to the external supply.
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.
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 1.6mA. In addition, it is recommended to inject the current as far
as possible from the analog input pins.
4. No negative current injection allowed on PB0 and PB1 pins.
5. When several inputs are submitted to a current injection, the maximum ΣIINJ(PIN) is the absolute sum of the positive and
negative injected currents (instantaneous values). These results are based on characterization with ΣIINJ(PIN) maximum
current injection on four I/O port pins of the device.
