Amlogic S805 Datasheet Released

A datasheet release should not really be news, but not all companies are as open as Freescale, and possibly for fear of IP theft or patent trolls, most companies decide to keep datasheet, technical reference manuals, and other documentation confidential, and only release them under NDA, so it may take months before they come out, if ever. Thanks to Hardkernel and their ODROID-C1 board, Amlogic has allowed the release of Amlogic S805 datasheet (PDF 123 pages).
