This document describes the known exceptions to the functional specifications for the device.
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 and support tools. Each device has one of three prefixes: X, P, or null (no prefix).
Device development evolutionary flow:
X — Experimental device that is not necessarily representative of the final device's electrical
specifications.
P — Final silicon die that conforms to the device's electrical specifications but has not completed quality
and reliability verification.
null — Fully-qualified production device.
X and P devices are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
X and P 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 (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.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the silicon
revision, the package type and the temperature range (for example, "T" is -40 to 105C).
