Guidance for Interfacing 7" 1024×600 LCD with STM32H743ZI

Hi,

We are planning to use STM32H743ZI for our project.

Our requirement is to interface a 7-inch LCD touch display with 1024x600 resolution using a 24-bit RGB interface (RGB888) through LTDC.

Can STM32H743ZI reliably support this display resolution? Also, what frame rate can realistically be achieved with this configuration?

Are there any important hardware or performance considerations before selecting this MCU?

Any suggestions or reference designs would be helpful.

Thanks.

Riverdi (among others) have a number of displays - up to 12.1" - based on H7:

ST have eval boards with 5/5.7" displays:

Thanks for the suggestion.

Could you please share the hardware design documents for the RVT70HSSFWN00 module, especially the schematics and any available reference design files?

It would be very helpful for understanding the LCD interface implementation and overall hardware architecture.

Hello @Kannika and welcome to the ST community;

AN4861 "Introduction to LCD-TFT display controller (LTDC) for STM32 MCUs"

https://www.st.com/en/partner-products-and-services/riverdi-stm32-displays.html

Using Riverdi board:

So yes it can interface 7" 1024×600 LCD with STM32H743ZI.

PS1: STM32H755 have the same LCD-TFT peripheral.

PS2: STM32H743ZI is a 144 package check if all LTDC signals are available on that package.

    You'd have to go to Riverdi for that - it's their product:

      Most important is SDRAM here ... And too DSI ?
