I just saw the image on your Facebook page.
If I am spoilering and that went up only by accident, just don't approve my post. :-)

But wow.
- two channel LVDS TX for displays with up to 1920 x 1200
- two channel LVDS RX for Video *input* up to 1920 x 1200
- "Embedded 1Gbit DDR3L SDRAM" - so 128MB of RAM
- "Advanced EVE with Frame Buffer support for High Resolution HMI"

This sounds like a pretty fundamental change.
First I was thinking that is a lot of memory.
But then I noticed the "Frame Buffer" part.

I am looking forward to learn how much "EVE" is left in "EVE-5".

Hi Rudolph,

Glad to hear that you like the new BT822 features.

Despite the frame buffer inside, we've retained the same features that made EVE so good and the screens are still created using the command/display lists etc. The frame buffer combined with the 16K RAM_DL will help with the more complex user interfaces without underrun etc. but from the application side it will still feel very familiar.

Even things like the video input are used via the EVE commands and so you can easily add video into your UI with overlaid touch buttons with a simple command list, we'll be publishing some examples etc. in future to show how to use these features.

But in the meantime we have just published this short article which covers some of the new features of the BT822 which we hope you find interesting https://brtchip.com/discover-bt822-next-evolution-bridgetek-5th-gen-eve/

Best Regards, BRT Community

Ok, wow more nice features.

- 16kiB display list
- SD card support
- Audio is Stereo now and output is by I2S
- integrated Watchdog timer
- enhanced touch engine
- live video feed

Looks like there won't be a resistive touch variant this time and I can totally see why.
Edit: from one of the pictures: "Supports resistive and capactive touch panels..." - ok, so maybe both in one chip this time?

I guess documentation will become available with the launch in october?
Right now I am wondering if I will be improving my EVE library to support EVE-5 or if it would be better to do a separate library.
The memory layout is likely completely different which would make a new library without EVE2/3/4 support cleaner.

Any ETA on the availability of modules with display from Matrix Orbital, Crystalfontz or Riverdi?
I am very interested in buying a module with a BT822, 7" would be my sweetspot in regards of desk space needed. :-)
Heck, I would use a 5" if this is the first I can get my fingers on. :-)

I'm keeping an eye on this new BT822 chip. 

Has memory been increased from 1 Mb to 1 Gb on the new BT822?

I have been a fan of EVE chips for years, who has directed his efforts to thoroughly explore the 23X gameduino library, created by James Bowman. So far it has worked on FT800/FT801, FT81x and BT81x; I ask you so excited that I can barely type on the keyboard... will it be possible to use this new BT822 with the gameduino 23X library?

PD: If the GPS that I have built and improved for several years with an FT813 chip, has been able to handle things that I had been told could not be achieved... I can already imagine what can be achieved with 1 Gb of memory!!!!

That is 1Gbit, so 128MB, which is still a lot more.

And in regards of gameduino library, you should check out other options.

[Rudolph]

One thing that just struck me, FT81x and BT81x do "only" have a 22 bit address range, so 4 megabyte.
Does this mean that the BT822 will be using a new memory model with a 30 bit address range in order to support the 27 bit needed to address the 128 megabyte of embedded DDR3L SDRAM plus FIFO plus DL plus registers plus external Flash and so on?

That would indeed be a fundamental change if the first bytes to be send is 32 bit instead of 24 bit and a change that I really would apreciate.

Hi Rudolph,
We will have the datasheet available in October which will have full technical details,

Ok, no more questions then, the suspense though. :-)

One final remark though, I noticed that the BT822 is using a 38.4MHz crystal on the "Block Diagram" image.
That is an odd value.
