In theorie yes.

Cool...

I was on "Karo" and thy have i.MX51, and Kirkwood on such Modules but it
is no real pleasure, because each enterprise change the pinlayout,  EVEN
if it could be standardised

I am ongoing to save money to order the Kirkwood  SO-Dimm  (99 Euro)  to
work me into this High-Performance Microcontroller.

The probem is, that you can not excangen a Samsung with a  Freescale  or
Marvell.  :-(

So, you have to build for each PCB manufacturer there own SO-Dimm module
which is realy sick.  Not even Freescales i.MX SO-Dimm modules have  the
same layout.  Otherwise I would have used them for one year already.

There are some reference designs laying arround.

Currently I try to get from all  interesting  ARM  microcontrollers  the
specs and reference designs, gerber files and whatelse because one of my
ideas is, to build SO-Dimm modules with  different  microcontollers  but
the same layout on the SO-Dimm pins.

Then in effect it dose not more mather HOW I desing my TablePC,  PanelPC
or a NetBook.  I can scale the performance of onDevice HOW I like.

OR, (better for pubicity) he CUSTOMER cn choose  a  computer  design  of
choice and put into whatever Microcontroller performance  s/he  want  to
have.

With the currently availlable SO-Dimm it is not possibel.

This mean, I have to buy from any intersting microcontroller an EVKit to
try it out and then re-build the SO-Dimm to our needs.

Do you have the schematics (reference design) for the SO-Dimm module?
The pinlayout does currently not mather.
