Hello TI,

We are use TM4c1294 to design a industry bus controller and want to expand the flash and ram on it.Is it possible to connect both SRAM and FLASH on EPI at the same time? Is there any refense design on this?

Thank you!

    Hello Bin,

    Yes, it is possible to connect SRAM and FLASH (TM4C only supports NOR Flash). There is no reference design as such but if you have an idea of which SRAM and Flash memories you want to connect to EPI, we can help you out in getting the connections

    Also do note that both memories need to be 16-bit or 8-bit. We do not support mix of data widths on the EPI Interface

    Regards
