To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of Radar / mmWave sensor devices. Each of the Radar devices has one of the two prefixes: XIx or IWRLx (for example: XI6432BGABL). These prefixes represent evolutionary stages of product development from engineering prototypes (XI) through fully qualified production devices (IWRL).
Device development evolutionary flow:
XI — | Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow. |
IWRL — | Production version of the silicon die that is fully qualified. |
XI devices are shipped with the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Texas Instruments recommends that these devices not to be used in any production system as their expected end –use failure rate is still undefined.
Figure 3-1 shows an example of the IWRL6432 Radar Device's package symbolization.
