Supported MCUs for 720*1280 DSI Display

[KAgga.1]

Hello There,

I'm new to DSI based Displays. We have got a DSI Display of 720(H) x 1280 (V) resolution which is based on ILI9881D and supports 2 Lanes.

I want to know whether STM32F469VET6 could support it? As I couldn't find any guide for this.

Any help is appreciated.

Two main limitations, the availability of sufficiently large frame buffer, and the ability to hit the timing and bandwidth expectations / limitations of a two lane interface.​

I​ think I've had a 1280x720 mode working on an F7 board

Thanks @Community member​ for replying.

Yes I'm aware that an external SDRAM will be required for such high resolution.

As per datasheet it supports displays 720p @30Hz. So, do you suggest F469 for this display?

That'd have a pixel clock up around 27-30 MHz, 16bpp, would perhaps be around 450 Mbps on the DSI

I'd probably not bother with F4 designs at this point unless you have some compelling design reason for using them over an H7 or F7

I'd design with a 32-bit wide SDRAM, and QSPI NOR FLASH via a SOIC16/SOP16(W) type foot-print or a dual SOIC8/16 foot-print to accomodate a broad array of sourceable parts.

VE package no. Cant connect SDRAM. F4 is lowest power, better is F7 or H7...
