8.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of
all devices and support tools. Each commercial family member has one of three prefixes: TMX, TMP,
or TMS (for example,TMS570LS1224). 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.
TMX and TMP devices are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
TMS devices 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.
