What ICs are used in this rocket?

[Faringdon]

Hi,
The space rocket that just launched to the moon...

What ICs are used on this for processors?  Atmel? Or they use FPGA only?

Also, what Power Supply control ICs are used?, eg, Analog.com , or they use vicorpower  modules?

You seriously expect anyone here to know what make of ICs or power modules are used in a Chinese Lunar probe? 

Troll.


Edit: Preserved OP original post.

this one is a little light on the effort put in by topic starter


there is like, a billion different space electronics solutions that are usable in space, depending on requirement. its probobly as cheap as possible, because its not a military satellite

so you want someone to write an entire time line of how electronics changed since the apollo missions.......

there that should answer your questions

[Kim Christensen]

They use space age technology.

Regrettably, it is typical of the effort.

[SiliconWizard]

I think the OP is trying to get into the space industry, and of course trying to figure out why China is gonna win this industry as well as with power supplies.

Watch CuriousMarc channel, they often post on (at least vintage) space electronics teardowns and repair.

For anyone who is curious as to the answer rather than just with Faringdon being a troll  .

Radiation-hardened FPGAs and microcontrollers/SoCs most likely if they are "old space". 

Or they could be using consumer devices with higher tolerance to single event upsets which is the SpaceX ("new space") approach - reasonably normal computers (they use x86 Intel processors of one kind or another) but with much redundancy and self-checking.

And aircraft aluminum. Billet only, of course.

That thread seems to imply that radiation hardened ICs and large scale redundancy are alternatives, but that's not really true. The two have usually been combined to achieve acceptable results.

So everything digital from Italy uses spaghetti logic 
And the USA has burger logic

and all the best noodles are now made in Taiwan.

The OP already has a thread on hardened semiconductors, discrete vs IC etc... https://www.eevblog.com/forum/renewable-energy/discrete-smps-have-any-advantages/

Quite why he wants to know the manufacturers of the silicon in this particular rocket is beyond me. Ed: Whether they use Vicor power modules, even more so.

Sometimes it also uses structural noodles, but payload and deltaV suffers...

The second question would be preparation for a crusade against Chinese/foreign/whatever PSU manufacturers.

A cynic might think it is just a troll, or so that he has yet another post to (uncritically) thank. The word "egoboo" springs to mind, albeit a rather twisted variant.

[Faringdon]

Thanks, most of the Chinese Power Supplies ive worked on, had  chips like UCC38C43 or Fairchild chips in them.
The only Chinese  ICs  i saw were the ON/OFF controlled type offline flyback  ones.
Or do the Chinese have their own speciality  power supply control ICs?,  but they don't make them sellable to the world outside of China?

[floobydust]

Considering OP's "friend" was apparently illegally selling semiconductors to the commies - and now he's asking what semi's are going into commie rockets?
We're being trolled yet again    I have to conclude he's working for 'em.

Now you're asking us again about stuff the commies have? All your "schematics" use Linear Tech parts - the most expensive in the business.
Did you finish your drone-making startup? Hint: china makes all the major components - rare-earth PM motors, cameras, batteries etc.
Plan your next trip to Shenzhen already.

Presumably they don't use the "offline flyback ones" because they don't have a long enough mains lead. They clearly lack your design skills, you should offer your services.

Right, but the approach SpaceX take is to tolerate SEUs in the downstream computers and correct them at the engine/controller level with much cheaper hardware which can be adequately radiation hardened without increasing the cost of the avionics too much.

Whereas the approach for "old space" might be to use rad-hard hardware everywhere and design for minimum fault occurrence.  See for instance the Space Shuttle computers, which were quintuple redundant (two could be lost with mission still OK to proceed; three with normal landing parameters; and four with a safe landing still possible) but these were also radiation-tolerant systems with much slower, older process geometry.  Practically everything on the craft will have been rad-hardened because "that's just how you do it".

Not aluminium, Chinesium.  At first glance it looks exactly like aluminium and is priced as such, but then once the return window has closed you find out it doesn't conduct electricity and dissolves in seawater.

Now you're asking us again about stuff the commies have? All your "schematics" use Linear Tech parts - the most expensive in the business.

Thanks, so do the Chinese have these kind of speciality  power supply control chips like the Analog.com ones, and the ti.com ones etc etc?
..but they just dont sell them to the rest of the world?
..or..So you are saying they only make the "big stuff"?, like the motors etc?

They do - plenty of PSU ICs available on LCSC, they're just harder to find due to LCSC's poor parametric search and the datasheets being in Chinese.

You can also see this in action sometimes when disassembling different generations of Chinese-made electronics, older versions will have recognisable parts in them, then they'll start sprouting vaguely-similar Chinese equivalents with minimal info available, and finally completely alien parts with no info available.  It's a bit like the SF movie/story Screamers / Second Variety which starts out with known devices and then over time they become more and more alien.
