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™ MCU devices and support tools. Each TMS320 MCU commercial family member has one of
three prefixes: TMX, TMP, or TMS (for example,
TMX
320F28377S). 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
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, PTP) and temperature range (for example, S).
provides a legend
for reading the complete device name for any family member.

TI sales representative.
