Hi to all.
The processor P89CV51RB2 is obsolete.
In the Mouser web page this component is show how obsolete.
plz help.
If the economics are not looking good a manufacturer will EOL a product, everything on a specific process/line if it breaks down (uneconomic to repair), test equipment or production equipment ceases to be available, catastrophic damage (earthquake, tsunami), or simply sell the fab, or move it to more profitable products.
If the last 5 years tells us anything, it's that 5 years is a long time for a product/part to be available.
Pretty much any SoC targeting a tablet/phone is 18 months at best. Producing today, doing something else, newer, tomorrow. The only constant is change.
and also that the rate of "obsolescence" is increasing
SILabs seems the least EOL crazy of the bunch.

I challenge you to mention one you mentioned it already. Any further challenges... ;) (pun intended).
Ya, i am aware of the obsolescence and its alarming rate. Hence people have developed and migrated to using OS (linux, WinCE) and writing applications.
"Hence people have developed and migrated to using OS (linux, WinCE) and writing applications."
That isn't progres. Especially since Linux and Win CE can often not be used for the relevant tasks...
Linux or Win CE isn't the route to avoid issues with embedded processors becoming obsolete. Lots of hardware needs programs that plays with the lowest levels of hardware. Linux or not, you still have to work with drivers, because stock drivers for a processor seldom supports the full hardware capabilities. Next thing is that Linux isn't an RTOS.
The only main difference that have happened, is that people use C or C++ instead of assembler, which means that a significant percentage of a program can often be reused. The hw mapping layer may have to be rewritten if switching to a processor in an other family or from another manufacturer.
The OP was talking about a P89CV51RB2 - so clearly not an application for WinCE or Linux.
Still, the OP doesn't actually seem to be interested - so I guess it doesn't really matter...
Hi again all.
You are right. I lost interest when it went off topic. then it went even more off topic.
i Think you people want to argue with yourselfs. you see who is best person to post cleverest answer. i am not interested in your games.
No. The thread didn't go off-topic. Your posts failed to describe your issues. You just thought that you did give enough information for anyone to know what to help with.
YES. the thread did go off topic. i did not say linux or wince!!!! i said P89CV51RB2, u think THAT can do wince or linux???? u think that linux or wince is on topic??? u think u are clever and u try to defend what u say by saying I am wrong. whatevr. i WILL NOT PLAY UR SSTUPID GAMES. U WIll of course reply and say i am stupid. BUT I DONT CARE BECAUSE I ALREADY SHOW U ARE A FOOL!
"U WIll of course reply and say i am stupid."
Do I really need to?
I SAID U WOULD!!!!!!!!!!!!!! GOODBYE MR SMART ***.
1) Your original post forgot to mention if you wanted help finding place to buy processor. Or find alternative processor. And for alternative processor, you didn't tell what was critical requirements. How can people help when you don't tell what you want help with.
2) You came back talking a totally different processor designed for totally different tasks. So small processor or large processor needed?
3) You then stay away from the thread for a long time.
4) You then come back and are rude. Maybe you play much computer games where you are used to be rude hidden behind an anonymous account? Doesn't work well for a public forum where you want help.
you mentioned it already. not6 really, while SILabs is good about6 not EOLing they will not guarantee 5 years
Pedro your initial question, and follow up, provide no detail about what you expect the processor to achieve. If you're using it for some specific task, attached to some specific equipment or sensors, it would be clearer as what solutions would be most applicable.
