10.2.2 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 family devices and support tools. Each TMS320 DSP member has one of three prefixes: TMX, TMP, or

TMS. TI 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:

SMX

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

SM/SMJ

Fully-qualified production device

Support tool development evolutionary flow:

TMDX

Development support product that has not yet completed TI 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 has 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. TI 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.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type

(for example, HFG, GNM, or GNL) and temperature range (for example, M). Figure 39 provides a legend for

reading the complete device name for any TMS320 DSP family member.
