IWR6843AOP Device Silicon ErrataSilicon Revisions 1.0 and 2.0

1 Introduction

This document describes the known exceptions to the functional and performance specifications to TI CMOS Radar Devices (IWR6843AOP).

2 Device Nomenclature

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: XI6843AOPQAGALB). These prefixes represent evolutionary stages of product development from engineering prototypes (XI) through fully qualified production devices (IWR).

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.
IWR —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.

3 Device Markings

Figure 3-1 shows an example of the IWR6843AOP Radar Device's package symbolization.

GUID-F43A2541-A4B3-436E-8A60-1665A9C6EF3D-low.gif Figure 3-1 Example of Device Part Markings

This identifying number contains the following information:

  • Line 1: TI Logo
  • Line 2: G1 = "Green" Package Build (must be underlined)
  • Line 3:
    • XIWR6843 = xIWR6843 Device Identifier (Pre-Production Industrial) , IWR6843 ES2.0 Device Identifier (Production Industrial)
    • BG ALP = Package Identifier
    • YM = Year/Month Code
    • Z = Assembly Site Code
    • LLL = Assembly Lot Code
    • 9 = Primary Site Code

4 Usage Notes

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.
