135 / 357 page  DS12110 Rev 10 135/357 STM32H742xI/G STM32H743xI/G Electrical characteristics (rev Y) 320 Prequalification trials Most of the common failures (unexpected reset and program counter corruption) can be reproduced by manually forcing a low state on the NRST pin or the Oscillator pins for 1 second. To complete these trials, ESD stress can be applied directly on the device, over the range of specification values. When unexpected behavior is detected, the software can be hardened to prevent unrecoverable errors occurring (see application note AN1015). Electromagnetic Interference (EMI) The electromagnetic field emitted by the device are monitored while a simple application, executing EEMBC code, is running. This emission test is compliant with SAE IEC61967-2 standard which specifies the test board and the pin loading. Table 56. EMI characteristics for fHSE = 8 MHz and fCPU = 400 MHz Symbol Parameter Conditions Monitored frequency band Max vs. [fHSE/fCPU] Unit 8/400 MHz SEMI Peak (1) VDD = 3.6 V, TA = 25 °C, UFBGA240 package, compliant with IEC61967-2 0.1 MHz to 30 MHz 6 dBµV 30 MHz to 130 MHz 5 130 MHz to 1 GHz 13 1 GHz to 2 GHz 7 Level (2) 0.1 MHz to 2 GHz 2.5 - 1.
