ERRATA

AWR1243 DeviceSilicon ErrataSilicon Revisions 1.0, 2.0, and 3.0

1 Introduction

This document describes the known exceptions to the functional and performance specifications to TI CMOS Radar Devices (AWR1243).

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: X1x or AWR1x (for example: AWR1243FBIGABLRQ1). These prefixes represent evolutionary stages of product development from engineering prototypes (X1x) through fully qualified production devices (AWR1x).

Device development evolutionary flow:

X1x —Experimental device that is not necessarily representative of the final device's electrical specifications and may not use production assembly flow.
AWR1x —Production version of the silicon die that is fully qualified.

X1x 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 AWR1243 Radar Device's package symbolization.

  • Line 3: Lot Trace Code
    • YM = Year/Month Code
    • PLLL = Assembly Lot
    • S = Assembly Site Code
  • Line 4:
    • 964 = AWR1243 Identifier
    • F = ES3.0
    • D = ES2.0
    • BLANK = ES1.0
    • ABL = Package Identifier
    • G1 = "Green" Package Build (must be underlined)
