TMS320DM643: Does the TMS320DM643 support 12-bit raw data input?

Hello Meiling,

As per the banner on the product page, there is no design support for this part:
https://www.ti.com/product/TMS320DM643

We cannot answer any hardware design or software design questions about this part number. The part is "active", which means that if you have an existing design, we will continue producing the part in our factories for a long time. For more information about the product life cycle, refer to https://www.ti.com/support-quality/quality-policies-procedures/product-life-cycle.html 

However, if you are creating a new design, I would suggest that you use a more recent device where we will be able to answer questions, like AM62Ax. If you have questions about part selection, I can send your thread to a member of our marketing team for further discussion.

Regards,

Nick
