This document describes the known exceptions to the functional and performance specifications to TI CMOS Radar Devices (AWR6843).

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: XAx or AWRx (for example: XA6843BGABL). These prefixes represent evolutionary stages of product development from engineering prototypes (XI) through fully qualified production devices (AWR).

Device development evolutionary flow:

XA 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 AWR6843 Radar Device's package symbolization.

This identifying number contains the following information:

• Line 1: Device Number
• Line 2: Safety Level and Security Grade
• Line 3: Lot Trace Code
  • YM = Year/Month Code
  • Z = Assembly Site Code
  • LLL = Assembly Lot Code
  • 9 = Primary Site Code
• Line 4:
  • 60 GHZi = AWR6843 (ES1.0) Identifier
  • 678A = AWR6843 (ES2.0) Identifier
  • 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.

The maximum SPI speed under 3-wire operation was only tested up to 33 MHz. This affects AWR6843 ES2.0.
