2 Nomenclature, Package Symbolization, and Revision Identification
2.1 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 (for example, TMS 320F28379D). 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 (with TMX for devices and TMDX for tools) through fully
qualified production devices and tools (with TMS for devices and TMDS for tools).
Device development evolutionary flow:
TMX Experimental device that is not necessarily representative of the final device's electrical specifications and
may not use production assembly flow.
TMP Prototype device that is not necessarily the final silicon die and may not necessarily meet final electrical
specifications.
TMS Production version of the silicon die that is fully qualified.
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."
Production 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 (X or P) 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, PTP) and temperature range (for example, T).
