Which MCU has 3 lane DSI interface

According to

http://www.st.com/content/ccc/resource/technical/document/application_note/group0/1d/b8/33/4f/dc/0a/45/52/DM00287601/files/DM00287601.pdf/jcr:content/translations/en.DM00287601.pdf

, STM32F4 includes DSI interface with up to 2 lanes. See page 15.

I am wondering if there is any MCU with 3 data lanes (L0, L1, L2) and CLK lane?

 Hi rostokus,

The STM32F469/479 devices embeded MIPI® DSI host controller supporting up to 720p 30Hz resolution.

The DSI Host provides a scalable architecture using one or two data lanes.The number of lanes depends on the bandwidth requirements of the application. Each DSI lane has a maximum of 500 Mbit/s data rate, for a total 1Gbit/s rate in dual data lane mode.

Further information are detailed in AN4861application note it may help you.

Hi Nesrine,

You said 'using one or two data lanes'.

But my questions is whether you have any MCU with three data lanes?

Recommended app note does not mention about 3 lanes (only two)

Thanks

Hi

rostokus

,

Unfortunately,there is no STM32 device with 3 DSI data lanes, the STM32 embeded maximum 2 data lanes.
