RM46L852: Compatibility of the TMDSEMU110-U debug probe with RM46L852 and RM57L843 MCUs

Hi Rafael,

Rafael Savariego said:

Please could you confirm me that TMDSEMU110-U is compatible with the MUCs indicated?

TMDSEMU110 debug probe supports all the Hercules controllers, that includes RM57L843 and RM46L852 as well.

You can verify below thread once, here customer successfully used this debugger with RM57x:

First of all, thank you very much for confirming the compatibility of the TMDSEMU110.

Secondly, could you please answer the other three questions:

• Question 2 y 3:

Rafael Savariego said:

On the other hand, the hardware development sheet for the RM57 and RM46 MCUs indicates that TMDSEMU200-U is a compatible JTAG debug probe, but I can't find the datasheet for that probe on the TI website. I have found a datasheet on the blackhawk website but I am not sure if that datasheet corresponds to the TMDSEMU200-U probe. Please could you confirm if the datasheet I just sent you corresponds to the TMDSEMU200-U? If not, could you please send me the documentation for the TMDSEMU200-U debug probe?

• Questions 4:

Finally, do you have any comparison between TMDSEMU110-U and TMDSEMU200-U? TMDSEMU200-U seems to be faster based on the answers from another forum question, but I don't know if it has any other advantages over TMDSEMU110-U.

Thank you very much!

Yes, the same datasheet will applicable.

Alongside i will also suggest you go through below link:

TMDSEMU200-U Debug probe | TI.com

Here you can find Features, as well as pinout information etc.

The XDS200 would give you a bit more performance at a higher cost:

You can refer below comparison table for more details:

Last question: What is the maximum TCK clock frequency that the TMDSEMU110-U and TMDSEMU200-U debuggers can generate?

For example, could I debug the RM46L852 at its maximum system clock frequency (220 MHz)?
