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 family member has one of three prefixes: TMX,
TMP, or TMS. 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
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 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, GJC), the temperature range (for example, blank is the default commercial temperature range),
and the device speed range in megahertz (for example, -167 is 167 MHz). Table 2 identifies the available
320C6701 devices by their associated orderable part numbers (P/Ns) and gives device-specific ordering
information (for example, device speeds, core and I/O supply voltage values, and device operating temperature
ranges). Figure 4 provides a legend for reading the complete device name for any TMS320
DSP family
member.
