6.1 Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of
all devices.Each device has one of three prefixes: X, P, or null (no prefix) (for example, xRM46L852).
These prefixes represent evolutionary stages of product development from engineering prototypes
through fully qualified production devices/tools.
Device development evolutionary flow:
x
Experimental 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
Fully-qualified production device.
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 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. 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.
The figure below illustrates the numbering and symbol nomenclature for the RM46Lx50 devices.
