Allwinner A10 vs. A10S

[Gabe Rowe]

Does anybody know the difference between Allwinner A10 vs A10S? 

Anybody have the datasheet for A10S or have a link to it someplace?

I noticed Amery added some code for A10S.

https://github.com/amery/linux-allwinner/commit/d193cc121388f6281650de1bf9e25a20170cef94

And here it is already in an HDMI stick:

I guess it might be pin compatible, but now there are some no connects?

I guess it may not have ethernet or camera interface or extra LCD outputs, so they can make the die smaller and save some money?

A10s appears to be what was previously called A12.

Nothing public.

But basically it's somewhere between A10 and A13. Not as featurefull as
A10, but a lot more generic than A13.

Yes, a mostly empty skeleton waiting for more info.

Interesting.

It's not pin compatible. A10s is a much smaller TFBGA336 package.

It has much of what we find in A10:

* Ethernet
* one 24-bit LCD interface (TTL / CPU only, no LVDS).
* one CSI camera interface
* HDMI
* Composite video out
* I2S audio interface
* Analog audio line in/out + headpones + mic.
* JTAG
* Several UARTS, of which one have full modem control lines, and most at
least CTS/RTS control lines.
* 32-bit DDR3-1066 up to 2GByte
* CedarX VPU
* Display engine, including format conversion, colour compensation,
layers & hardare cursor/pointer.
* GPS processor core

What is missing:

* no G2D accelerator.
* no composite video in.
* no RGB out (VGA)
* no LVDS LCD interface
* probably no SATA interface
* one USB less than A10

Excellent info thanks!!!

Any idea how much cheaper it is? Maybe $5 in large qty?
