• Operates as a single-chip solution for 76-GHz to 81-GHz automotive radar sensing
• Utilizes a compact 161-lead FC/CSP package for space-constrained designs

Applications

• Automotive proximity sensors
• Automotive radar systems
• Short-range detection applications

Procurement Notes

Verify the specific ordering suffix against the official Texas Instruments datasheet to ensure correct package type and temperature rating. Confirm that the requested part matches the exact functional specifications required for the target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Ensure all electrical and mechanical parameters align with the design requirements before finalizing procurement orders.

Selection Notes

Select this component when a fully integrated radar solution is required without external processing units. The choice depends on the need for combined RF, baseband, and processing functions in a single package. Consider the 161-FC/CSP footprint constraints during PCB layout planning. Evaluate the thermal performance requirements given the specified operating temperature range. This part is suitable for applications prioritizing integration density over modular flexibility.

Part Context

This component belongs to the AWR1843 series of single-chip radar sensors. It is part of Texas Instruments' portfolio of wireless and RF integrated circuits designed for automotive use. The series includes variants with different packaging options such as FCCSP and FCBGA. These devices are engineered to meet automotive reliability standards and provide complete radar functionality on a single die.

Replacement Considerations

Check for other AWR1843 variants with different package codes if physical footprint changes are acceptable. Verify compatibility with existing power management solutions like TPS65313-Q1 or TPS65653-Q1. Ensure substitute parts maintain the same 76-GHz to 81-GHz operational range and integration level.
