This document describes the known exceptions to the functional and performance specifications to TI CMOS Radar Devices (IWR1443).

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 IWRx (for example: IWR1443FQAGABL). These prefixes represent evolutionary stages of product development from engineering prototypes (XI) through fully qualified production devices (IWR).

Device development evolutionary flow:

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 IWR1443 Radar Device's package symbolization.

This identifying number contains the following information:

• Line 1: Device Number
• Line 2:Temperature and Security Grade
• Line 3: Lot Trace Code
  • YM = Year/Month Code
  • PLLL = Assembly Lot
  • S = Assembly Site Code
• Line 4:
  • 964 = IWR1443 Identifier
  • D = ES2.0
  • FC = ES3.0
  • BLANK = ES1.0
  • ABL = Package Identifier
  • G1 = "Green" Package Build (must be underlined)

Usage notes highlight and describe particular situations where the device's behavior may not match presumed or documented behavior. This may include behaviors that affect device performance or functional correctness. These usage notes will be incorporated into future documentation updates for the device (such as the device-specific data sheet), and the behaviors they describe will not be altered in future silicon revisions.
