Device Nomenclature

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

microprocessors (MPUs) and support tools. Each device has one of three prefixes: X, P, or null (no prefix)

(for example, your device). 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 (TMDX) through fully qualified production devices and tools (TMDS).

Device development evolutionary flow:

Experimental device that is not necessarily representative of the final device's electrical

specifications and may not use production assembly flow.

Prototype device that is not necessarily the final silicon die and may not necessarily meet

final electrical specifications.

null

Production version of the silicon die that is fully qualified.

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.

X and P devices and TMDX development-support tools are shipped against the following disclaimer:

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 (for example, your device). 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 and TMDX) through fully qualified production

devices and tools (TMS and TMDS).

Device development evolutionary flow:

TMX

Experimental device that is not necessarily representative of the final device's electrical

specifications and may not use production assembly flow.

TMP

Prototype device that is not necessarily the final silicon die and may not necessarily meet

final electrical specifications.

TMS

Production version of the silicon die that is fully qualified.

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."

Production 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 (X or P) 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.
