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, GDH), the temperature range (for example, “A”is the extended temperature range), and the device speed range in megahertz (for example, -300 is 300 MHz). Figure 2-10provides a legend for reading the complete device name for any TMS320C6000™ DSP platform member.

The ZDH package, like the GDH package, is a 256-ball plastic BGA, but Green.

For device part numbers and further ordering information for TMS320C672x in the GDH, ZDH, and RFP package types, see the Texas Instruments (TI) website at http://www.ti.com or contact your TI sales representative.

²The extended temperature ªA versionº devices may have different operating conditions than the commercial temperature devices. For

more details, see the recommended operating conditions portion of this data sheet. ³ BGA = Ball Grid Array

TQFP = Thin Quad Flatpack

§The ZDH mechanical package designator represents the Green version of the GDH package. For more detailed information, see the
