Allwinner released recently their T2 SOC targeting automotive entertainment panels.
Looking at the specs we saw that it suspiciously looks like A20.
This is not the first time Allwinner releases their old silicons under new names like A13-R8, A33-R16, R40-T3 etc. I personally find this quite confusing.
We got some T2 samples and now assembly A20-OLinuXino-LIME, A20-OLinuXino-LIME2, A20-OLinuXino-MICRO and A20-SOM with them to test for hardware and software compatibility.
Once we are sure everything works OK will release T2-OLinuXino boards which will be with industrial temperature grade -40+85C for all components on the boards.
To this moment all our A20-XXX-IND boards has components for or exceeding -45+85C, but A20 SOC was specified -20+70C.

The names are because of Allwinner’s lunatic scheme of competing business units. Each business unit has a different letter.
The competing business unit scheme was in vogue in the US during the 1980’s and it was a complete disaster. Far too much is wasted internally when the groups don’t cooperate.

Is this just a qualification testing issue or are there in general any differences between normal and ext. Temp versions to expect?

I wonder if the T2 is fabbed at lower nanometers to reduce power consumption ?
It would be good to measure operating and standby currents and comparing this to the A20, to prove if this were possible.
The A20 was 55nm ?
