7 Device and Documentation Support

TI offers an extensive line of development tools for the device platform, including tools to evaluate the

performance of the processors, generate code, develop algorithm implementations, and fully integrate and

debug software and hardware modules. The tool's support documentation is electronically available within

the Code Composer Studio™ Integrated Development Environment (IDE).

The following products support development of the device applications:

7.1 Device 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., TMS320C6745). 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, ZWT), the temperature range (for example, "Blank" is the commercial

temperature range), and the device speed range in megahertz (for example, "Blank" is the default).

Figure 7-1 provides a legend for reading the complete device.
