STM32L162VD, STM32L162ZD, STM32L162QD, STM32L162RDElectrical characteristics8. The max. value may be exceeded if negative current is injected on adjacent pins.9. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. ThisMOS/NMOS contribution to the series resistance is minimum (~10% order).Output driving currentThe GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink orsource up to ±20 mA with the non-standard V OL /V OH specifications given in Table 48.in the user application, the number of I/O pins which can drive current must be limited torespect the absolute maximum rating specified in Section 6.2:●●The sum of the currents sourced by all the I/Os on V DD, plus the maximum Runconsumption of the MCU sourced on V DD, cannot exceed the absolute maximum ratingI VDD (see Table 8).The sum of the currents sunk by all the I/Os on V SS plus the maximum Runconsumption of the MCU sunk on V SS cannot exceed the absolute maximum ratingI VSS (see Table 8).Output voltage levelsUnless otherwise specified, the parameters given in Table 48 are derived from testsperformed under ambient temperature and V DD supply voltage conditions summarized inTable 10. All I/Os are CMOS and TTL compliant.Table 48.Output voltage characteristicsSymbol Parameter Conditions Min Max UnitV (1)(2)OLV (3)(2)OHOutput low level voltage for an I/O pinwhen 8 pins are sunk at same timeOutput high level voltage for an I/O pinwhen 8 pins are sourced at same timeI IO = +8 mA2.7 V < V DD < 3.6 V2.40.4(1)(4)V OLV (3)(4)OHOutput low level voltage for an I/O pinwhen 8 pins are sunk at same timeOutput high level voltage for an I/O pinwhen 8 pins are sourced at same timeI IO =+ 4 mA1.65 V < V DD
