Low end MCUs with EEPROM or Flash memory can be rewritten.
MCUs in home appliances have no EEPROM or Flash for program code at all. They made with masked ROM. Sometimes there is small EEPROM like 24CXX near to store settings, but it is data, not code.
EEPROM/Flash is expensive and could take up to 70% of MCU price. So large batches with masked ROM ordered by home appliances manufacturers.
Sorry buddy. Russia is retarded.
Absolutely. Believe me, I live here, Russia is retarded as fuck.
Of course, good luck sourcing all the equipment for that and supply chain of high grade silica.
That is another problem some try to solve here. There even exist equipment, but it is not working or damaged. In USSR was several enterprises that produced high grade silica plates, so tech is known. As far as I know currently only one enterprise produce decent plates, but they are small diameter, so not very useful for manufacturing large chips - it is much better to place many chips on one plate, than to be limited with few.
So, again it is just a question of financing, not tech.
So, if you wish Russia lose, than you should pray WEF, IMF and other bastards will continue to sabotage us via their shills in our government.
Open your dishwasher or microwave and take a look.
You could find ARM with flash only in something really "smart", IDK, photoframe or fridge that order products from Amason automatically.
There are a lot of ARM SoCs with OTP memory too. They are cheaper, so widely used in mass production.
PICs is rare thing in home appliances. I found them only in some car ECUs, like windows ECU or central locks. And in relatively old cars only.
Most home appliances have Hitachi, Toshiba, Renesas(NEC), China native or some unidentified COBs MCUs.
Especially those cheap brands that are common in Russia and even more in Ukraine. There are not many Miele wasing machines around. (Really don't know what MCU Miele use, may be same masked/OTP as cheap ones)
By the way, best chance to obtain a useable, flasheable MCU, potentially suitable for some military purpose is button mobile phones, photoframes, dash cameras, car radios and advanced RC toys.
If that dumbfucks told their shit about above stuff as a source for chips for Russian military, than, at least, it would heave been plausible. But in no case it could be dishwashers/microwaves.
That is how blatant propaganda could be easily caught and that is why knowledge is very important nowdays.
Maybe they want the power electronics for something like small motor / compressor controls
That is produced in Russia, Belarus and China without any problems. It is large scale devices, so no any shortage.
Russia don't produce high capacity DRAM, Flash memory, highly integrated processors that need low nanometer process and high resolution CMOS cameras. But all that things produced in China.
Processors of level used in home appliances produced in many varieties and, more important, in military grade versions (ceramic case with gold plated pins and thorough testing including radiation) you never find in home appliances.
That would make sense to steal from appliances.
In home appliances mostly triacs used to drive motors/coils. You rarely will find good power MOSFETs inside. Triacs much cheaper. Triacs are for AC, so no use for DC military things.
Again, to scrap powerful MOSFETs you need PC power supplies (at least there will be 2 high voltage low current and 1-2 low voltage high current), not diswashers and microwaves.
Most microwaves don't have any power electronics at all, just a single relay to turn on magnetron and motor of rotating plate.
Again, that thing about dishwashers and microwaves for chips is a pure and blatant lie.
I think it's plausible to identify secondary sources of cheap MCU with eeprom or flash memory from smart appliance that would work in a Russian tank
Hardly you will find anything pin-to-pin compatible around, that could be replaced in the field, really.
May be it is possible to find something for night vision or targeting display system in some industrial equipment, but I can't imagine reballing under the artillery fire.
Tanks electronics replaced by modules, not by resoldering chips, even in service stations. Broken modules sent to manufacturer for proper repair if it is allowed.
(I mean for the type of dumb shit you use cheap like 28-pin type MCUs for in "automotive" type applications.. boring stuff like limit control on a hydraulic actuator... the stuff that does get repaired.. not the high end stuff people picture in their mind..)
You perfectly know, that Russians are retarded, so that modern fashion with doing simple things with MCUs are not yet came in (fortunately ?). In Russian tank limit control for hydraulic actuator will be made without electronics at all. As simple and reliable as possible with minimum parts. Even in newest models.
