75 / 110 page ![]() DocID027513 Rev 4 75/110 STM32L081xx Electrical characteristics 95 6.3.11 Electrical sensitivity characteristics Based on three different tests (ESD, LU) using specific measurement methods, the device is stressed 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) are applied to the pins of each sample according to each pin combination. The sample size depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test conforms to the ANSI/JEDEC standard. Static latch-up Two complementary static tests are required on six parts to assess the latch-up performance: A supply overvoltage is applied to each power supply pin A current injection is applied to each input, output and configurable I/O pin These tests are compliant with EIA/JESD 78A IC latch-up standard.
