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 (e.g.,
TMX320DM647ZUT720
). 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).
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 have 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, ZUT), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, "Blank" is the default
[720-MHz]).
