PRODUCTION DATA.
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all microprocessors (MPUs) and support tools. Each device has one of three prefixes: XMS, PMS, or MSP. These prefixes represent evolutionary stages of product development from engineering prototypes through fully qualified production devices and tools.
Device development evolutionary flow:
Experimental devices and tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices and 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 have a greater failure rate than the standard production devices. TI 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, ZAD) and the temperature range (for example, blank is the default commercial temperature range). Figure 8-1 shows a legend for reading the complete device name for the device.
For orderable part numbers of the device, see the Package Option Addendum of this document, ti.com, or contact your TI sales representative.
For additional description of the device nomenclature markings on the die, see the device-specific silicon errata.
