This is a stress rating only and func- tional operation of the device under these condi- tions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability. 11.2.1 Voltage Characteristics 11.2.2 Current Characteristics 11.2.3 Thermal Characteristics Notes: 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 coun- ter). To guarantee safe operation, this connection has to be done through a pull-up or pull-down resistor (typical: 4.7k Ω for RESET, 10k Ω for I/Os). Unused I/O pins must be tied in the same way to V DD or VSS according to their reset con- figuration. 2. When the current limitation is not possible, the VIN absolute maximum rating must be respected, otherwise refer to IINJ(PIN) specification. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. 3. Power (VDD) and ground (VSS) lines must always be connected to the external supply. 4. 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 1mA (assuming that the impedance of the analog voltage is lower than the specified limits). - Pure digital pins must have a negative injection less than 1mA. In addition, it is recommended to inject the current as far as possible from the analog input pins.
