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:
X
Pre-production device that is not necessarily representative of the final device's electrical
specifications and may not use production assembly flow.
P
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.
