device and development support tool nomenclature

To designate the stages in the product development cycle, Texas Instruments assigns prefixes to the part

numbers of all TMS320 devices and support tools. Each TMS320 member has one of three prefixes: TMX, TMP,

and TMS. 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). This development flow is defined

below.

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 fully characterized, and the quality and reliability

of the device have been fully demonstrated. Texas Instruments standard warranty applies.

Predictions show that prototype devices (TMX or TMP) will 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 is still undefined. Only qualified production devices are to be used.
