i have some doubts with respect of the reliability of the Microcontrollers from some time ago
i know that the engineer have to make a good desing with the hardware and the software taking considerition like electrical noise, use of varistor, electrical fuses(not the fuses that we use in the software) and other things
but my questions are:
why people use ARM architecture to embedded desing and not other, what have of special ARM CORTEX?
why are microcontroller of aeronautic grade more reliable(i guess)?
are automotive and other kind of microcontroler reliable?
how often would they fail? (example 1 in 100.000.000,00)
its not necesary that you answer all or exactly answer those questions, but if you can give me some idea of the topic i would be thankfull :) saluts
