A typical embedded system, let's say Transmission or Power Train Electronic Control Unit (ECU) is powered by automobile Battery.

Battery voltage is at 12 Volts. If the battery voltage drops to 0 Volts in 5 us and stays at 0 V for 100 us, then rises back to 12V in 5 us, what impact will this have on Microcontroller memories, different microcontrollers inputs like Analog, Digital, PWM, etc. And different outputs like Digital, PWM etc.

Will the contents of I/O and memories like SRAM, Program Flash, Data Flash change due to this transient?

The microcontroller on the ECU is Infineon Aurix Tricore TC29x.

The big capacitors will keep your board powered during the black period.

If the capacitors are not big enough, your board will power down and start a power on reset when the voltage arises again.
