LCD-TFT project with 1024x768 resolution. Which MCU to use?

[Acelink]

Hi guys, sorry if I'm posting this in the wrong area.

I'm starting a project that uses a 1024x768 graphics display and I was wondering which STM32F MCU  (LQFP 176pin) would be the better to drive the RGB Panel. I would be using external memory but if there is a MCU with internal memory that can display 1024x768 that would be easier and would make the project cheaper as well.

Can you please let me know as soon as possible as at this stage I'm doing the research on what I need before I purchase all the parts.

Thanks guys and hope to hear from you soon.

Hi,

so for a 1024x768 pix display, the first question is : what it should show ?

Maybe hi-speed video or animation for a game - or GUI for process or machine controlling ?

So for a GUI , and using a "small " cpu (compared to the SOCs used in mobile phones) , its good idea, to use a display with onboard graphics and frame buffer , so the cpu just giving graphic commands to the display, connected with a SPI .

I use the TFTs with EVE graphics, the TFT has almost same price range as a plain "***" TFT frame.

Just look at mouser...

btw 1024x768 seems very unusual , more is : 800x480 , 1024x600 or 1280x800 ;

or look at displays, with STM cpu already there...

... many others also, just ask google :)

You ask MCU then STM32U5 is only one with internal RAM sized for single buffer RGB565 optimaly, or moremore power new N6...

Display you can choice RGB or better DSI.

Thanks for the info but it's not what I'm looking for. They have 8080 or 6800 16bit interfaces which is just to slow for our project. 

Thanks for the info anyway.

Thanks for the info. I just checked out a few of the STM32U5 and none that I reviewed uses the RGB interface, only MIPI. Our project uses RGB interface with Hsync, Vsync signals.

Also the STM32N6 series is BGA package so we can't prototype with it. Only LQFP 144pin or 176pin.

Do you have any other suggestions?

So look yourself...

with RGB par. -> maybe STM32H7R3Z8 , 144pin lqfp.

all have RGB ... STM32U5G9J-DK2 - Discovery kit with STM32U5G9ZJ MCU - STMicroelectronics

but check pinouts 

[Acelink]

Ok I must of missed the RGB interface page. Yes the STM32UG9ZL looks great.

I'll download all the reference manuals, datasheets etc and see if its suitable.

Oh, we'll be designing out own PCB for this chip. I know I have to use STM32CubeIDE to write the code but do you know which debugger I need to use to download my code to the flash? 

Thanks again for your help, I very much appreciate it.
