1.10.2.1 Device and Development-Support Tool Nomenclature

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP

devices and support tools. Each DSP commercial family member has one of three prefixes: TMX, TMP, or TMS

(e.g., TMS320DM641GDK600). Texas Instruments recommends two of three possible prefix designators for

its 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

TMS

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, GDK), the temperature range (for example, blank is the default commercial temperature

range), and the device speed range in megahertz (for example, -600 is 600 MHz). Figure 1−7 provides a

legend for reading the complete device name for any DSP platform member.

The ZDK package, like the GDK package, is a 548-ball plastic BGA only with Pb-free balls. The ZNZ package

is the Pb−free version of the GNZ package.

For device part numbers and further ordering information for TMS320DM641/DM640 in the GDK, GNZ, ZDK

and ZNZ package types, see the TI website (http://www.ti.com) or contact your TI sales representative.
