This document describes the known exceptions to the functional and performance specifications to TI CMOS Radar Devices (IWR2944).

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of Radar / millimeter Wave sensor devices. Each of the Radar devices has one of the two prefixes: XIx or IWR2x (for example: IWR2944ABSALT). These prefixes represent evolutionary stages of product development from engineering prototypes (XIx) through fully qualified production devices (IWR2x).

Device development evolutionary flow:

XIx 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 IWR2944 Radar Device's package symbolization.
