Micron DDR part number

Hallo, I have bought an evaluation board where supplier has chenged the ddr chip without notice.

I have made lots of searches but I haven't found anything.

Could someone tell me which chip has the following codes, please?

The chip has the Micron logo and:

6CF22 D9GCM

and into a corner LDV5

Many Thanks, Marco T.

Marco, the first thing to learn is how to find information. you could have got the answer yourself, I am confident, but instead of,ok

on the micron website there is special page with script that "decodes" the device markings to the part number. hopefully you can find it now.

Hi Antti, if you talk about the "Product Search" -> "Part Number"

I already tried it, but it replies that the code I used it's not valid.

Sorry, could you tell me which link are you talking about?

Thanks, Marco T.

I told you need the "decoder page" from micron website. (i did not give you the link directly, but I told what is what you need: the "decoder"...)

so here, FULL LINK

formatting link

from this page you get: Part Number FBGA Code MT46V32M16FN-6:F D9GCM

if you are unable to find this information AFTER you have been told WHERE to look and WHAT to look, then if you dont improve your learning eager, well you never manage anything in this live.

other people will not always do your homework. you need to understand this, and you will manage better in the future.

I found this thread rather troubling; designers seem apathetic to the volatility and rapid obsolescence of technology and information, especially to Internet-hosted data -- if it isn't current, abandon it and design anew, if it is 'mature', disparage it and consider the life-cycle complete. In this case, pity the poor soul who will need to 'decode' some unfortunate manufacturer-imposed 'house number' system with a proprietary 'decoder' when the manufacture abandons the part or the online resources supporting it. There may even be IP issues if a third-party establishes an independent system for 'decoding' such things in the absence of manufacturer support.

In an age of high-capacity low-cost (of acquisition and operation) mass storage, why is it beyond the pale for manufacturers to host access to their obsolete datasheets (with the proviso that they offer no design support if necessary), instead of unceremoniously pulling them at the end of a product's life? I am still searching for some very much needed datasheets that surely readers of this NG have or have once possessed but never replied in the affirmative to some of my previous requests...

Anyone care to commiserate on this issue?

Regards,

Michael

different issues:

1) product life cycle 2) "product marking"

- the decoder on micron site, is a GOOD and needed tool, as it converts the marking that DOES NOT FIT on the package into full part number. so its nothing wrong with that. when reasonable part code can not be printed onto the package then it is ok to use special marking, and a way to decode it.

of course the this could also be included in the smart search box at micron site, automatically decoding any valid FBGA marks...

Your post might be more useful if you listed at least some of your missing datasheets. As it is it is a pure whine.

Whine perhaps, but more a bitter lament. I worked with the technical archives at Control Data and NCR Comten for many years; _every_ manual, drawing, wirelist, BOM, etc. for _every_ product _ever_ made by these firms was carefully preserved and made available for reference, and _external_ reference as well. Vendor reference files occupying thousands of square feet with schematics, listings, brochures, etc. covering the industry were also maintained. If firms of this size could do this in a paper era, surely mega- multinational-conglomerate manufactures today can maintain some PDFs for external access!

I did not list any datasheets since on previous occasions the results have been deafening silence or rebukes for using old technology.

Three examples from this list involved in current projects are:

  1. Sanyo LA1205 (in English) (note: I have scanned images of a Japanese version; would someone who reads Japanese be willing to translate?)
  2. Intel 8096 User Manual and Reference Guide (not 80C196xx) (note: 80C196KA/KB manuals have been useful to me but they do not fully document important differences in the original 8096 product)
  3. QED or IDT R5230 Manual/Reference

Internet and Usenet searches for these have failed previously, and requests to vendors are in vain.

Regards,

Michael

What's a 'learning eager'?

BTW, I thought the OPs response was reasonble considering his first language probably wasn't english. Confusing decoder with search is a relatively minor slip.

Now let's hope someone springs to life with the appropriate data :-).

Ask in sci.electronics.components or sci.electronics.repair.

...

Those were published as chapters in Intel's various microcontroller databooks. Intel was playing musical databooks at that point. (dig, dig, dig) In 1985, "Microcontroller Handbook" (for the '96, '51 and '48). In 1988, it was "Embedded Controllers, Vol. II 16-Bit..." (for the '96 and '188). And in 1990, "16-Bit Embedded Controllers" (for the '96 and '196).

I would be surprised if none of those have been scanned and put on the net.
