9.1.2

Device and Development Support-Tool Nomenclature

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

MPUs and support tools. Each device has one of three prefixes: X, P, or null (no prefix). 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

(TMDX) through fully qualified production devices/tools (TMDS).

Device development evolutionary flow:

Pre-production device that is not necessarily representative of the final device's electrical

specifications and may not use production assembly flow.

Prototype device that is not necessarily the final silicon die and may not necessarily meet

final electrical specifications.

null

Production version of the silicon die that is fully qualified.

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.

X and P devices and TMDX development-support tools are shipped against the following disclaimer:

"Developmental product is intended for internal evaluation purposes."

Production 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 (X or P) 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.

9.1.3

Device Nomenclature

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the

package type (for example, AAR), the temperature range (for example, blank is the default commercial

temperature range), and the device speed range (for example, 01 is the 720 MHz ARM device). Figure 9-1

provides a legend for reading the complete device name for any DM385 device.

For device part numbers and further ordering information of DM385 devices in the AAR package type, see

the TI website (www.ti.com) or contact your TI sales representative.
