Electrical characteristicsSTM32L162VD, STM32L162ZD, STM32L162QD, STM32L162RDPrequalification trialsMost of the common failures (unexpected reset and program counter corruption) can bereproduced by manually forcing a low state on the NRST pin or the oscillator pins for 1second.To complete these trials, ESD stress can be applied directly on the device, over the range ofspecification values. When unexpected behavior is detected, the software can be hardenedto prevent unrecoverable errors occurring (see application note AN1015).Electromagnetic Interference (EMI)The electromagnetic field emitted by the device are monitored while a simple application isexecuted (toggling 2 LEDs through the I/O ports). This emission test is compliant withIEC 61967-2 standard which specifies the test board and the pin loading.Table 43.EMI characteristicsMax vs. frequency rangeSymbol Parameter ConditionsMonitoredfrequency band4 MHzvoltagerange 316 MHzvoltagerange 232 MHzvoltagerange 1UnitS EMIPeak levelV DD = 3.3 V,T A = 25 °C,LQFP100 packagecompliant with IEC61967-20.1 to 30 MHz 3 -6 -530 to 130 MHz 18 4 -7 dBµV130 MHz to 1GHz 15 5 -7SAE EMI Level 2.5 2 1 -6.3.11 Absolute maximum ratings (electrical sensitivity)Based on three different tests (ESD, LU) using specific measurement methods, the device isstressed in order to determine its performance in terms of electrical sensitivity.Electrostatic discharge (ESD)Electrostatic discharges (a positive then a negative pulse separated by 1 second) areapplied to the pins of each sample according to each pin combination. The sample sizedepends on the number of supply pins in the device (3 parts × (n+1) supply pins). This testconforms to the JESD22-A114/C101 standard.Table 44.

STM32L162VD, STM32L162ZD, STM32L162QD, STM32L162RDElectrical characteristicsStatic latch-upTwo complementary static tests are required on six parts to assess the latch-upperformance:● A supply overvoltage is applied to each power supply pin● A current injection is applied to each input, output and configurable I/O pinThese tests are compliant with EIA/JESD 78A IC latch-up standard.Table 45.Electrical sensitivitiesSymbol Parameter Conditions ClassLU Static latch-up class T A = +105 °C conforming to JESD78A II level A6.3.12 I/O current injection characteristicsAs a general rule, current injection to the I/O pins, due to external voltage below V SS orabove V DD (for standard pins) should be avoided during normal product operation. However,in order to give an indication of the robustness of the microcontroller in cases whenabnormal injection accidentally happens, susceptibility tests are performed on a samplebasis during device characterization.Functional susceptibility to I/O current injectionWhile a simple application is executed on the device, the device is stressed by injectingcurrent into the I/O pins programmed in floating input mode. While current is injected into theI/O pin, one at a time, the device is checked for functional failures.The failure is indicated by an out of range parameter: ADC error, out of spec currentinjection on adjacent pins or other functional failure (for example reset, oscillator frequencydeviation, LCD levels, etc.).The test results are given in the following table.Table 46.I/O current injection susceptibilityFunctional susceptibilitySymbolDescriptionNegativeinjectionPositiveinjectionUnitI INJ Injected current on all 5 V tolerant (FT) pins -5 +0Injected current on true open-drain pins -5 +0mAInjected current on any other pin -5 +5Doc ID 022268 Rev 2 89/124
