AWR1843ARBSALPQ1

Overview

The AWR1843ARBSALPQ1 is a single-chip 76-GHz to 81-GHz automotive radar sensor featuring an integrated antenna on package, DSP, and MCU. It operates within a temperature range of -40°C to +125°C and utilizes a 180-pin FCCSP package. The device supports a maximum data rate of 900 Mbps with an output power of 12 dBm. Power supply requirements are between 1.14 V and 1.32 V. Program memory size is 2 MB.

Feature Summary

• Integrates antenna directly onto the package for compact form factor
• Combines RF front-end with digital signal processing and microcontroller units
• Designed specifically for automotive radar applications

Applications

• Automotive radar sensing
• Advanced driver assistance systems (ADAS)
• Autonomous driving perception

Procurement Notes

Verify the specific suffix ALPQ1 against official Texas Instruments documentation to confirm package type and qualification status. Ensure compatibility with automotive environmental standards before procurement. Cross-reference ordering part numbers with manufacturer datasheets to avoid substitution errors due to minor suffix variations.

Selection Notes

Select this component when an integrated antenna-on-package solution is required to minimize board space. Consider the 180-pin FCCSP footprint for layout constraints. Evaluate the 76-81 GHz frequency band suitability for target resolution and penetration requirements in automotive environments compared to other family members.

Part Context

This model belongs to the AWR1843 family of single-chip mmWave sensors. It shares core processing capabilities with variants like AWR1843ABGABLQ1 but differs in packaging and integration level. The ARBSALPQ1 variant specifically denotes the antenna-integrated FCCSP configuration distinct from standard BGA packages.

Replacement Considerations

Direct substitutes include other AWR1843 variants such as AWR1843ABGABLQ1 or AWR1843ARBGALPQ1, provided the package difference (FCCSP vs BGA) is accommodated in the design.
