69 / 106 page  DocID15081 Rev 10 69/106 STM32F100xC, STM32F100xD, STM32F100xE Electrical characteristics 105 Electromagnetic Interference (EMI) The electromagnetic field emitted by the device is monitored while a simple application is executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with IEC 61967-2 standard which specifies the test board and the pin loading. 5.3.12 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 JESD22-A114/C101 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/JESD78 IC latch-up standard.
