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 family devices and support tools. Each TMS320
DSP 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). This development flow
is defined below.
Device development evolutionary flow:
SMX
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
SM/SMJ
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 has 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, HFG, GNM, or GNL) and temperature range (for example, M). Figure 13 provides a legend for
reading the complete device name for any TMS320
DSP family member.
