10.2 Device Nomenclature Boilerplate

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 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:

Device development evolutionary flow:

    TMX Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow.
    TMP Prototype device that is not necessarily the final silicon die and may not necessarily meet final electrical specifications.
    TMS 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.

TMX and TMP 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.
