AWR1843ARBGALPRQ1

Overview

The AWR1843ARBGALPRQ1 is an integrated single-chip FMCW radar sensor operating in the 76 to 81 GHz automotive band. It utilizes a 45nm low-power process and integrates ARM Cortex-R4F and C674x DSP cores. The device features six ADC channels, four transmit channels, and twelve receive channels with a maximum data rate of 900 Mbps. It supports I2C, SPI, and UART interfaces within a 161-FCBGA package.

Feature Summary

• Integrates RF transceiver and processing cores for compact system design
• Supports high-resolution imaging through multiple TX and RX channels
• Complies with automotive functional safety standards

Applications

• Automotive blind spot detection
• Rear cross traffic alert systems
• Adaptive cruise control sensors

Procurement Notes

Verify that the specific suffix ALPRQ1 matches the required tape-and-reel packaging configuration for automated assembly lines. Confirm that the component meets AEC-Q100 qualification requirements for the target automotive environment. Ensure compatibility with existing reference designs for signal integrity validation prior to mass production deployment.

Selection Notes

Select this model when operation within the 76-81 GHz spectrum is mandatory for regulatory compliance or performance needs. Choose this SoC over discrete solutions to reduce board space and power consumption. Consider the integrated DSP capabilities for on-chip signal processing requirements without external processors.

Part Context

This part belongs to the AWR1843 family of automotive-grade mmWave sensors. It shares architectural similarities with industrial variants like the IWR1843 but includes specific automotive certifications. The device represents a generation of high-performance radar sensors designed for advanced driver assistance systems.

Replacement Considerations

The AWR1843ABGABLQ1 serves as a tray-packaged alternative within the same functional family. Verify package type differences if reflow profiles differ significantly between reel and tray configurations.
