 Posted: Mon Aug 29, 2011 8:51 pm Post subject: VIA processors |
 |
|
CPUshack nicely took a scan of a random selection of green chips in the VIA lot I purchased before packing them away in a box on its way to me.
Thought I would show a few that were in the lot
and there is a few there I need to work out what exactly they are

First time to see so many different type of VIA processor. 
Thanks for sharing.  |

There are some interesting ones  . I've never seen top right in VIAStu2.jpg. It is also interesting VIA Nano without capacitors (but they were damaged probably?). I always thought that these green cpus with two chips were early dual core prototypes (as I saw them in photos quite earlier before any dual core CPU were released and there were no information about quad-core) however I am not sure currently.

appears to be two standard Nano cores on the one chip
probably before they shrunk the cores and put both on one die

I had a think and look around about this one 
My best guess at the moment is 2 Nano CPUs on the one die.. before they shrank the die process to the current size

I have managed to list all the markings on the Nano out of the lot
https://docs.google.com/spreadsheet/ccc?key=0AkdFFomYaIrxdDhSTFJvLTJKTEozaHQzdmM3dEFFYXc&hl=en_US#gid=0
Have managed to work a few things out, like 15Wxxxx is Wafer 15 with the xxxx denoting the X & Y placement on the wafer
early parts were listed in long hand eg. W06_X12Y15
later parts just used a short version eg. 16W2215
CN was used by Centaur as the code name for the Nano
guessing the letter following are process & stepping
earlier ones (marked CNAxx) are from the 1000 & 2000 series processors, with the later ones (marked CNBxx) from the 3000 series

I really would like to see pics of your "storage" room.
Like one of those XXXXL walk-in humidors with 500.000 pieces? |

I would take one of those zeros off 
its a bit of a mosh pit at the moment with the latest 100+ kgs of stuff from Avicc spread over the place 
I will start logging the C7s and the oddball newer VIAs and see what I find, then I will start posting pics

thought I would take photos of a random selection of the VIA CPUs
first lot are Eden & C7s

a random selection of Nano with only test markings
the earliest has the FPO engraved on the die

some production marked Nano
and early examples of Nano X2s before they combined / shrank the dies
