116 / 202 page  Electrical characteristics STM32F446xC/E 116/202 DocID027107 Rev 6 6.3.15 Absolute maximum ratings (electrical sensitivity) 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 latchup Two complementary static tests are required on six parts to assess the latchup 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 Table 52.
