device and development support tool nomenclature (continued)

Support tool development evolutionary flow:

TMDX

Development support product that has not completed TI’s 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 fully characterized, and the quality and reliability

of the device have been fully demonstrated. 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, PN, PQ, and PZ) and temperature range (for example, L). Figure 16 provides a legend for reading

the complete device name for any TMS320x2xx family member.
