The extended temperature “A version” devices may have different operating conditions than the commercial temperature devices. For
more details, see the recommended operating conditions portion of this data sheet.

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 2-10 provides 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.
