Device and Development-Support Tool Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all

TMS320 DSP devices and support tools. Each TMS320 DSP commercial family member has one of three

prefixes: TMX, TMP, or TMS (e.g., TMS320VC5407/TMS320VC5404). Texas Instruments recommends two

of three possible prefix designators for 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

TMS

Fully qualified production device

Support tool development evolutionary flow:

TMDX Development-support product that has not yet completed Texas Instruments internal qualification

testing.

TMDS Fully qualified development-support product

TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer:

“Developmental product is intended for internal evaluation purposes.”

TMS devices and TMDS development-support tools have been characterized fully, and the quality and

reliability of the device have been demonstrated fully. TI’s standard warranty applies.

Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard

production devices. Texas Instruments recommends that these devices not be used in any production system

because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.
