device and development-support tool nomenclature
To designate the stages in the product-development cycle, TI assigns prefixes to the part numbers of all SMJ320
devices and support tools. Each SMJ320 member has one of three prefixes: SMX, SM, or SMJ. 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 (SMX / TMDX)
through fully qualified production devices/tools (SMJ / TMDS).
Device development evolutionary flow:
SMX
Experimental device that is not necessarily representative of the final device’s electrical
specifications
SM
Final silicon die that conforms to the device’s electrical specifications but has not completed
quality and reliability verification
SMJ
Fully qualified production device processed to MIL-PRF-38535
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
SMX devices and TMDX development-support tools are shipped against the following disclaimer:
“Developmental product is intended for internal evaluation purposes.”
SMJ 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 ( SMX or SM) 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, GLP), the temperature range, and the device speed range in megahertz (for example, 16 is
167 MHz). Figure 4 provides a legend for reading the complete device name for any SMJ320 family member.
