To designate the stages in the product development cycle, TI assigns prefixes to all part numbers and/or date-code. Each device has one of three prefixes/identifications: X, P, or null (no prefix) (for example, XCC2651P3 is in preview; therefore, an X prefix/identification is assigned).

Device development evolutionary flow:

Support tool development evolutionary flow:

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.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, RGZ).

For orderable part numbers of CC2651P3 devices in the RGZ (7-mm x 7-mm) package type, see the Package Option Addendum of this document, the Device Information in Section 3, the TI website (www.ti.com), or contact your TI sales representative.
