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 TX29x.

Correction! The Microcontroller is Infineon Aurix Tricore TC29x

 

Ranging from deadly too trivia, depending on the nature of the transient.

 

Why is your battery dropping to zero volts and what is the source of that action?

 

Electronics for vehicles are designed to cope with the vagaries expected: varying voltage, transients, and radiated and conducted interference.

 

How much voltage will your on-board capacitors lose in 110 microseconds?

The effect should be zero because processor power supply should solve this.
A switched power supply is used plus a capacitor bank to deliver the energy needed to overcome.
The switch power supply will filter positive and negative going spikes ( in the automotive high power spikes could hit the +/- 100V)

Popular electronics. A 8 - 10 page 'DIY how to' pamphlet stretched into a 80 - 100+ page magazine by advertisement stuffing.

The internet, only on paper.

Your point? I find the ads to be the biggest reason to read technical magazines. I hope others do too or I'll have to stop placing my one-page ads in three different weekly magazines. Oh, wait, then one out of four new customers wouldn't find me.

My point is I found the excessive adverts, honestly most issue they did outnumber the useful pages and info on said pages my a near magnitude of order, to be something I didn't like that made the magazine largely unreadable. Much like the internet is now without adblock apps turned on and set to maximum kill and even then too much of that crap still sneaks through.

As far as I was concerned it was a advertizing magine with an occasional good article on how something worked or how to build something.

When I need some thing I will go and find it but until then I don't need a bunch of greedy money hungry fools shoving their crap in my face to show me what they have and where to get it when I don't have any want need or use for it.

That's my point and to be honest until I need something I rather hope everyone who spends and receives their money on advertising to excess where I don't want to see it in starves to death all slow and miserable like.

As far as most people I tend to think they feel as I do. If they didn't there wouldn't be a competition between search engine /web browser providers and other software providers to draw in new customers by having a better ad blocker and popup blocker systems than the other guys have.
They advertise their wares by showing that they don't let others crap advertising get to you better than anyone else.

Well, that's your mistake. They are really technical catalogs intended to make you a shopper. If you want a technical journal, you'll have to subscribe to a technical journal and pay the price of a technical journal. I'm surprised a strong, independent guy like you wants something for nothing. Those technical articles don't write themselves.

PS: Don't respond to say "but I paid a subscription..." Those subscriptions don't even cover postage and printing. The subscription only proves to advertisers that you are an interested party - so interested that you will pay $0.50 to $3 per issue - In other words, the publisher can show the advertisers that they've corralled a target audience of interested parties. How interested? Well, did you pay $0.50/issue, or $4.00 per issue? What ever it was, the publisher and advertiser use that and the total circulation numbers to determine how much a full-page ad costs.

I'm a strong independant guy because I have zero interest or want for paying for crap I don't want or need.

I had a popular electronics subscription for about a year because I got sold on the supposed

Popular Electronics was created in 1954 by Ziff-Davis Publishing for an audience of electronics hobbyists and experimenters.

http://www.americanradiohistory.com/Popular-Electronics-Guide.htm

but quickly found out it was nothing but a bullshit advertising rag posing and a pseudo magazine for hobbyists and experimenters in order to target a captive audience that had little to no other alternative to work with at the time.

I suspect the vast majority of its followers felt the same way being it crashed and burned in the early 2000's once the internet came to be and the concept of online forums that were dedicated to such hobbies and related interest that didn't have the loads of advertising crap in the way on every page emerged and evolved into what we have now.

Before the internet I used to subscribe to loads of similar hobbyists and enthusiasts magazines in a number of different areas and by far popular electronics was the shittiest one out there for having the least relevant content to what its name and supposed intent and target market was.

Most every other magazines I subscribed to ran near the polar opposite and had maybe 10% advertising filler for the given content (the best ones even stuck all that shit on the last pages and not all over every page too!) and that's the standard I expected of what I was paying for. The one or two others that didn't use that advertizing format and were more like popular electronics got dumped as soon as my first subscription ran out.

I for one bought a magazine for its content not for it's advertising crap just the same as I watch a show for its content not for the whatever commercials and advertising crap they fill it with and even with that now I only watch shows via downloading that have had every commercial cut out of them first.
