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 (e.g., TMS320C6412GNZA500, TMS320C6412GDK600). 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, GDK), the temperature range (for example, blank is the default commercial temperature
range), and the device speed range in megahertz (for example, -600 is 600 MHz). Figure 27 provides a
legend for reading the complete device name for any TMS320C6000
DSP platform member.
