A10 was one of most successful chips made by Allwinner, for couple of years it was top seller in tablets and other devices, A10 also was selected for our EUR 30 low cost Linux board the LIME.
Then Cortex-A8 single core become obsolete, then Allwinner released A20 – Dual Core more powerful and power efficient Cortex-A7 processor with pin to pin backward compatibility to A10.
This was incredible wise move for Allwinner as people could just re-use their old PCB designs without spending time to change PCBs.
A10/A20 had one nice feature – they have LCD, HDMI, SATA, Ethernet, in A20 Allwinner even add Gigabit Ethernet on top of the normal 100M Ethernet. All other new devices they release have either LCD either HDMI but not both and we miss SATA interface in all new Quad core devices they released.
Now they did it again – we got information from Allwinner that they are about to release Quad core more powerful processor which to be pin to pin compatible with A10/A20 we still don’t know the name, maybe A40 ? 🙂
Anyway this is very clever move as all existing designs which people have can be re-used. This means more modern SoC with more power but without forcing you to re-design your boards.
So expect Quad core LIME soon and I guess at same price range like other LIMEs!
