203 / 226 page  ST7FOXF1, ST7FOXK1, ST7FOXK2 Electrical characteristics 203/226 12.8.3 Absolute maximum ratings (electrical sensitivity) Based on two different tests (ESD and LU) using specific measurement methods, the product 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 pin). Two models can be simulated: Human Body model and Machine model. This test conforms to the JESD22-A114A/A115A standard. For more details, refer to the application note AN1181. Static latch-up (LU) 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 the EIA/JESD 78 IC latch-up standard. Table 85. ESD absolute maximum ratings Symbol Ratings Conditions Maximum value(1) 1.
