Tool/software:
Hi
Hope you are doing well I’d like to ask the same question because want to make sure that if SM320C6678 and TMS320C6678 pin and functional compatible or not? As you know Aselsan is using C6678 but now they have some temperature problems. They would like to replace it with SM320C6678- HIREL. So want to make sure that there will not be any effort on HW as well as SW side.
Mustafa,
Software will be common/generic base as it uses C66x.
As per the device NOMENCLATURE,
=============================
2.9.2 Device Support 2.9.2.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices and support tools.
Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS (e.g., TMX320CMH). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
• TMX: Experimental device that is not necessarily representative of the final device's electrical specifications
• TMP: Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification
• SM: Fully qualified production device Support tool development evolutionary flow:
• TMDX: Development-support product that has not yet completed Texas Instruments internal qualification testing.
• TMDS/TMS: Fully qualified development-support product

Both should be PIN compatible.
However, Kyle will comment on Functional PIN compatibility.
Both are
