AMD Datamatrix method

[Drago]

Hi,

I just read the updated info on the AMD Athlon XP 3200+ - AXDA3200DUV3C and it says: "When we encoded serial number Y290235B23216 using the same method as AMD uses, we received quite different image."

Now, could you please describe this method and tell me if there is an online generator or free program that uses this method?

I tried many online code generators but never managed to get a fitting datamatrix when entering the serials of at least 10 CPUs.

So please, tell me!!!

Thanks
Drago

As an example, I will use serial number Y882632C41109 from the second picture on this page:

http://www.cpu-world.com/CPUs/K7/AMD-Athlon%20XP%203200%2B%20-%20AXDA3200DKV4E.html

Enter it here:

Compare the results.

Athlon XP and early Athlon 64 processors encoded only serial number. Newer Athlon 64 / 64 X2 and all Athlon X2, Athlon II, and Phenoms encode part number and serial number.

Okay, so this works for earlier CPUs.

But how do you enter part and serial? Space, no space, first part, second serial, other way around?

I tried this with part ZD320121K2324 and serial FA73482H90004 for example, the result doesn't fit, any of those ways above didn't work.

Okay, that one's an Engineering Sample that cpu-world doesn't list, I believe it to be Athlon II x2 260 but with unlocked multiplier.

You think this might be because of the sample or because I entered it wrong?

AMD changed encoding in 2008 to <serial number>_<part number>, for instance, FA73482H90004_ZD320121K2324. While this encoding worked for me for some processors, it didn't work for many others. Maybe AMD changed it again for more recent processors.

Ah, that did the trick.

BUT: The Generator in your link doesn't produce the correct result since it obviously doesn't use ASCII encoding.

These two generators http://www.bcgen.com/datamatrix-barcode-creator.html, http://www.automation.siemens.com/mcms/industrial-sensors/de/code-lesesysteme/Documents/datamatrix.htm allow you to change the encoding format and entering your scheme with ASCII results in the correct code.

Thanks for your help man, most appreciated.
