Device and Development-Support Tool Nomenclature

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

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

or TMS (for example,TMS570LS1114). 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.

TMS

Fully-qualified production device.

TMX and TMP devices are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes."

TMS devices 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.

The figure below illustrates the numbering and symbol nomenclature for the TMS570LS1114 .
