Question

Are there any documentations about FSMC layout?

I am now designing a board for STM32F103VET6 and would like to use the FSMC to control the TFT LCD (320x480 resolution)

May I ask if there are any notes or guides that mention the layout requirements? Such as what conductor impedance should the data lines have and what is the maximum difference in length between data lines?

Thanks!

Did you check out  the 'Documentation' tab on the Product Page?

Yes, but none of the 3 FSMC-related documents mentioned about the trace impedance.

There's 4 documents.

Would've helped to say that you'd already looked in those!
