9 Device and Documentation Support

TI offers an extensive line of development tools. Tools and software to evaluate the performance of the device,

generate code, and develop solutions are listed below.

9.1 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, TDA4VM). 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:

"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.

For orderable part numbers of TDA4VM devices in the ALF package type, see the Package Option Addendum of

this document, the TI website (ti.com), or contact your TI sales representative.

9.1.1 Standard Package Symbolization

Note

Some devices may have a cosmetic circular marking visible on the top of the device package which

results from the production test process. In addition, some devices may also show a color variation in

the package substrate which results from the substrate manufacturer. These differences are cosmetic

only with no reliability impact.
