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. 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 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. 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.

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

(for example, PZ, PGE, PBK, or GGU) and temperature range (for example, L). Figure 14 provides a legend

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