Intel produced SoCs for mobile devices, concretely Speatrum SC9853i and Spreadtrum SC9861G-IA. If you want to scale even further down, consider Intel Quark (https://en.wikipedia.org/wiki/Intel_Quark https://en.wikipedia.org/wiki/Intel_Quark). For an analysis why it failed in the market, consider http://linuxgizmos.com/who-killed-the-quark/ http://linuxgizmos.com/who-killed-the-quark/ To me, it seems that the central reason why these chips failed commercially is that at the lower end, SoCs offer a much thinner margins than CPUs for laptops, desktop PCs and servers.
