device and development-support tool nomenclature
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., TMS320C6711DGDP250). Texas Instruments recommends two of three possible prefix designators for 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
TMDS Fully qualified
TMX and TMP devices and TMDX
“Developmental product is intended for internal evaluation purposes.”
TMS devices and TMDS
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
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, GDP), the temperature range (for example, blank is the default commercial temperature range and A is the extended temperature range), and the device speed range in megahertz (for example,
The ZDP package, like the GDP package, is a
