AM335x Industrial communication profibus slave device

Other Parts Discussed in Thread: PROFIBUS, AM3356

For the industrial communication profibus slave device using AM335x (the part number proposed would be AM3356).

Is it possible to implement the profibus slave on AM3356 without DDR?

As we know, AM335x had 64k internal RAM and 64k Shared RAM. Are we able to execute profibus slave completely from internal memory (without DDR)?

If not, can you please suggest what is the minimum DDR size requirement for profibus slave?


Thanks.

    Hello Joseph,

    Thanks for your interest.

    Yes, The P/N would be AM3356. It's possible to eliminate the DDR but it depends on your application size and the feature set that your application needs. You can email me at gurrapu@ti.com so we can discuss more about your application needs and see if this is possible,

    Thanks,

    Srik

    Joseph,

    the Profibus example in IA-SDK does have several different project configs. The NOR and IRAM should work without DDR required. Just try this and have a look at the .map files to see required memory sizes.
