Device and Development Support Tool Nomenclature
K.1 Device and Development Support Tool Nomenclature
To designate the stages in the product development cycle, Texas Instruments
assigns prefixes to the part numbers of all TMS320 devices and support tools.
Each TMS320 member has one of three prefixes: TMX, TMP, and TMS. Texas
Instruments recommends two of three possible prefix designators for its sup-
port 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 de-
fined below.
Device Development Evolutionary Flow:
TMX
TMP
TMS
Support Tool Development Evolutionary Flow:
TMDX Development support product that has not yet completed Texas
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 fully character-
ized, and the quality and reliability of the device has been fully demonstrated.
Texas Instruments standard warranty applies.
Note:
Predictions show that prototype devices (TMX or TMP) will have a greater
failure rate than the standard production devices. Texas Instruments recom-
mends that these devices not be used in any production system because
their expected end-use failure rate is still undefined. Only qualified produc-
tion 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, N, FN, or GB) and temperature
range (for example, L). Figure K–1 provides a legend for reading the complete
device name for any TMS320 family member.

Experimental device that is not necessarily representative of the final
device's electrical specifications.
Final silicon die that conforms to the device's electrical specifications
but has not completed quality and reliability verification.
Fully qualified production device.
