Hai All

Seeking some unsual parts at local store sometimes didnt found cause uneconomic sale(rare in bought).
If some buyers looking the same parts or appears commecial electronic products
and need maintanance then the stores will in deposit.

Since the 62512 pDIP is old part.Probably the factories used others code IC.

Any information are welcome for 62512 pDIP

Why does this look like spam?
Are you looking for information on a 62512?

I have maybe 50 to a hundred cache ram chips left over from old 486 computers.

Some have the memory size in the type number, others don't.

So don't search for type numbers, search for the functionality.

 

I went to octopart, selected SRAM in dip packages.

Then there were still 300 enties left in the table and you can further refine by ram size.

Nowadays most big shops have parametric search engines like this

And even in small shops such as futurlec you can easily order some:

I don't know what you consider "quantities".

You migt want to reconsider to do a whole redesign and use a uC with more ram than you need for less than a separate ram chip.

OK, I'll Bite,

 

What are you building that you need a large quantity of obsolete, discontinued parts for?

I don't recall there being a 62512 - I think it went 62256 then 621024. Besides what chip are we talking about? a 64kx8 sram?

The 62512 is a 64kx8 SRAM from what I found through Google.

The OP has several threads all centered around needing large quantities of old parts for a big production run, or words to that effect.  I am starting to think a troll is amongst.

Then I am even thinking that it is a broker who is trying to get old parts very cheaply and then making a fortune out of re-selling.

I have had the pleasure of working with a couple of companies that had to keep old products alive. as in their customers world doing a re-design would cost a fortune by itself, so doing a quick PCB update to accommodate a newer part to replace an obsolete part was not an option.
