Electrical characteristicsSTM<strong>32</strong>L162VD, STM<strong>32</strong>L162ZD, STM<strong>32</strong>L162QD, STM<strong>32</strong>L162RD6.2 Absolute maximum ratingsStresses above the absolute maximum ratings listed in Table 7: Voltage characteristics,Table 8: Current characteristics, and Table 9: Thermal characteristics may cause permanentdamage to the device. These are stress ratings only and functional operation of the deviceat these conditions is not implied. Exposure to maximum rating conditions for extendedperiods may affect device reliability.Table 7.Voltage characteristicsSymbol Ratings Min Max UnitV DD –V SSV IN(2)External main supply voltage(including V DDA and V DD ) (1)–0.3 4.0Input voltage on five-volt tolerant pin V SS −0.3 V DD +4.0Input voltage on any other pin V SS −0.3 4.0|ΔV DDx | Variations between different V DD <strong>power</strong> pins 50|V SSX −V SS | Variations between all different ground pins 50V ESD(HBM)Electrostatic discharge voltage(human body model)see Section 6.3.11VmV1. All main <strong>power</strong> (V DD , V DDA ) and ground (V SS , V SSA ) pins must always be connected to the external <strong>power</strong>supply, in the permitted range.2. V IN maximum must always be respected. Refer to Table 8 for maximum allowed injected current values.Table 8.Current characteristicsSymbol Ratings Max.

All main <strong>power</strong> (V DD , V DDA ) and ground (V SS , V SSA ) pins must always be connected to the external <strong>power</strong>supply, in the permitted range.2. Negative injection disturbs the analog performance of the device. See note in Section 6.3.17.3. Positive current injection is not possible on these I/Os. A negative injection is induced by V IN V DD while a negative injection is induced by V IN < V SS . I INJ(PIN)must never be exceeded. Refer to Table 7: Voltage characteristics for the maximum allowed input voltagevalues.5. When several inputs are submitted to a current injection, the maximum ΣI INJ(PIN) is the absolute sum of thepositive and negative injected currents (instantaneous values).80mA50/124 Doc ID 022268 Rev 2
