Two STM32H743 series MCUs are on a single board and they communicate using SPI. When SPI clock frequency is more than 1.5 Mhz, SPI communication is not working properly. The distorted clock signal waveforms at high frequencies are attached below.A 51...

How to calculate the power consumption of STM32H743 from datasheet, theoretically as close as possible to the actual value? What parameters should be considered?Also, I want to calculate the heat generated from MCU -- dissipated power (in W). How to ...

Can someone please help with how to calculate the series current limiting resistors to be connected from STM32H7 or any MCU to transceivers or any other interfaces? Is there a general thumb rule followed? Also how to calculate the wattage of resistor...

Need help with identifying the right TVS diode for load dump protection of our device. The test standard is MIL-STD-1275E which has 28V nominal working voltage with Ri = 0.5 ohm. The surge has a pulse duration of 50ms, Us = 100V, 5 number of pulses w...
