MSPM0L1105: TRACE_ID not unique

Hello Catarina,

Can you help to double check whether the chip is RTM version. In theory, the trace value of each RTM chip should be different.

Hello Janz,

Thanks for your fast reply. I believe the chips are RTM, I am not sure if this helps, but one of the samples has the following written:

35A2FLK

L1105T

277

Hello Catarina,

Thanks for your new important information. I want to confirm with you: 

1). Where is the position the "35A2FLK, L1105T, 277" written to? screen printing?
2). This one chip's trace value is also 0x0 ?

Best Regards,

Hello Janz,

Here are some pics of what I gathered.

MUC registers (using Code Composer Studio):

Hello Catarina, 

I have got your meaning and I will try to read the TRACE ID of L1105 on my side. By the way, can you also provide one picture of the screen printing of other chips because according to your description " but one of the samples has the following written:", it seems that other chips have different screen printing ?

Hi Janz,

All the other 3 chips I checked also have it at 0, as can be seen on the following pics:

Hello Catarina,

Thanks for your more information but I mean that what are the screen printing of other 3 chips ? Are they all " 35A2FLK L1105T 277 " ? IF not, can you take pictures for me ? Much thanks for your help

Hello Catarina,

Can you help to see the seal time of the chip you purchased which is marked on the sealed bag? After discussed with my colleague, the trace ID of some earlier batches of RTM chips may be 0x0h.
