Could you please add a description of the SoC?  Perhaps a link to
documentation, or at least a slick sheet?  Also, are there any products
on the market with this SoC, which ones?

thx,

Hi,

it is low cost (?) SoC targeted for market in China and India which
trying to "replace" AT91SAM9G25.

Here is some info:
