AWR1843ARBGALPQ1

Overview

The AWR1843ARBGALPQ1 is a single-chip automotive radar System on Chip (SoC) operating in the 76 GHz to 81 GHz frequency range. It integrates an ARM Cortex-R4F core, 2 MB of program memory, and 2 MB of SRAM data RAM. The device features six ADC channels with 10-bit resolution and supports a maximum data rate of 900 Mbps. It delivers 12 dBm output power and operates within a voltage range of 1.14 V to 1.32 V. The component is housed in a 180-FCBGA package measuring 15 mm by 15 mm with a height of 0.435 mm. It functions reliably between -40°C and +125°C.

Feature Summary

• Integrates a high-performance ARM Cortex-R4F processor for efficient signal processing tasks.
• Provides six analog-to-digital converter channels with 10-bit resolution for detailed radar sensing.
• Supports high-speed data transmission up to 900 Mbps via integrated interfaces.
• Delivers consistent 12 dBm output power for reliable long-range detection capabilities.

Applications

• Automotive blind spot detection systems
• Surround view monitoring applications
• Adaptive cruise control sensors

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature grade. Confirm that the procurement channel provides valid traceability documentation for automotive-grade components. Ensure that storage conditions comply with moisture sensitivity level requirements prior to assembly. Cross-reference the manufacturer part number against official Texas Instruments databases to avoid counterfeit risks.

Selection Notes

Choose this model when a compact 180-ball BGA footprint is required for space-constrained automotive designs. Select this variant over the ABGA package if the specific pinout or thermal characteristics of the ARBG package are necessary for the PCB layout. Consider the integrated ARM Cortex-R4F core if complex onboard processing is needed without external microcontrollers.

Part Context

This component belongs to the AWR1843 family of 76-81 GHz automotive radar SoCs from Texas Instruments. It shares functional similarities with the AWR1843ABGABLQ1 but differs in its physical packaging configuration. The ARBGALPQ1 designation indicates a specific lead-free and tape-and-reel or tray packaging option distinct from the ABGA series.

Replacement Considerations

The AWR1843ABGABLQ1 serves as a direct functional alternative with identical electrical specifications but utilizes a different FCBGA-161 package. Designers must verify mechanical compatibility and pin mapping before substituting the ABGA package for the ARBG package.
