TMS320C6746: Compatibility between TMS320C6746EZWTD4 and TMS320C6746EZWTA3

Part Number: TMS320C6746

Tool/software:

Hi,

I am currently using the TMS320C6746EZWTD4 in my design,

but due to supply constraints, I am considering replacing it with the TMS320C6746EZWTA3.

Could you please confirm if these two devices are functionally and electrically compatible,

and if they can be used interchangeably without any firmware or hardware changes?

If there are any differences (e.g., speed grade, temperature range),

I would appreciate detailed clarification.

Thank you.
