MSPM0G1519: Missing RTC_B unit in SDK

Oleksandr Ohlashennyi

Part Number: MSPM0G1519
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hello!

While checking the MSPM0G1519 MCU found that RTC_B is missing in the “mspm0g151x.h” file of the MSPM0 SDK(2.04.00.06), when the datasheet does not limit the availability of the RTC unit on MSPM0G151x devices.

Screenshot from “SLASFA2A – NOVEMBER 2024 – REVISED APRIL 2025”

Comparison of “mspm0g351x.h” and “mspm0g151x.h” in the SDK version 2.04.00.06

Is there a specific reason for the absence of RTC for this controller? Will this peripheral be supported in the future?

Hi, thanks for the question. I am not sure why it is not showing up in that particular header file, but the RTC_B is supported based on enabling it in Sysconfig (see below). It may have been moved into another header file, but the MSPM0G1519 does have the capability of using the RTC. Hope this helps!

Hello and thank you, Brian, for your answer!

Yes, I can confirm that RTC_B does show up in the Sysconfig GUI, but the software is not compilable when RTC_B is enabled. Does it on your side?

Yes I am seeing that as well now, looks like the header file is missing the RTC defines. We are working to address this and will have this corrected in the next SDK release. Appreciate you bringing this to our attention, we will get this fixed on our end as soon as possible!
