x220 and x230 Official datasheets and manuals

Just to have them easy to find because I had to change some things related to intel AMT and I didn’t have them at hand.

Beware of the EC controller it seems they ended up using a different one (based on 8051 instead of ARC)
I suspect they used the SMSC FDC37N972:

Intel Ivy followed Sandy and I found nothing new related to EC:

http://www.intel.com/content/dam/www/public/us/en/documents/design-guides/3rd-gen-core-lga1155-socket-guide.pdf

http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/3rd-gen-core-desktop-vol-1-datasheet.pdf

There is nothing of interest on those documents. Appart from:

“This 3rd generation Intel Core processor
family and Intel® 7 Series chipsets are
pin and package compatible with the 2nd
generation Intel Core processor family
and Intel® 6 Series chipsets, allowing
developers to mix and match processors
and chipsets to better suit their design
needs”

So basically Lenovo _did_ innovate (sarcasm) and didn’t follow previous IBM designs or intel and went to a cheaper embedded controller but in order to be cheap they probably recycled a lot of code from somewhere else. They might even have ignored Phoenix but that is unlikely. x220:

Intel recomended way of connecting things (uses a Renesas H8S/2117 as a Embedded Controller)
