DEVICE#B063

Francis,

Could you tell me which exact part number you are using?

This errata only apply on specific devices and may not be applicable on yours.

Hello Jean-Marc

I am using spnz195d.pdf

It can also be found on spnz193d.pdf.

Regards,

Francis.

Hello again,

I am also using revision C of the TMS570LS31x/21x

Regards,

Francis.

Francis,

These are not partnumber but device family.
Can you tell me the marking on the device?

Hello Jean-Marc

On the device I can read TMS570LS3137CZWTQQIYFC-39C7V3W

I know what TMS570LS3137CZWT means, but what is the meaning of the last part QQIYFC-39C7V3W?

(As far as I know we are using TMS570LS3137 revision C package ZWT. I did not know that there were more sub-classes of the device)

Regards,

Francis.

Francis,

Q – temp rating

Q1 – Automotive qualification

Rest of it looks like lot trace code to me.

Hello Jean-Marc,

Thanks for the info but this is not answering my initial question.

I asked:

"I can see that in the errata sheet  (spnz195b.pdf) there is errata DEVICE#B063.

I understand the issue, but what I do not understand is is condition

"1. A logic power domain is disabled at reset by a factory OTP setting"

under what circumstances might these happen?

"

and you replied: 

"Could you tell me which exact part number you are using?

This errata only apply on specific devices and may not be applicable on yours."

Thanks,

Francis.
