4.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
TMS320 DSP devices and support tools. Each TMS320 DSP commercial family 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).
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 with 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, GQW or ZQW) and temperature range (for example, “Blank” is the default temperature
range). Figure 4−1 provides a legend for reading the complete device name for the TMS320UC5405 device.
For device part numbers and further ordering information for TMS320UC5405 in the GQW and ZQW package
types, see the TI website (http://www.ti.com) or contact your TI sales representative.
