- Designed for high-performance automotive sensing applications
- Supports cascading configurations for expanded channel counts
Applications
- Automotive blind spot detection systems
- Advanced driver assistance systems (ADAS)
- Surround view monitoring
Procurement Notes
Verify that the specific suffix matches the required silicon revision and packaging configuration. Confirm AEC-Q100 qualification status for automotive integration. Ensure compatibility with existing board designs regarding the 161-LFBGA footprint and thermal requirements before finalizing procurement orders.
Selection Notes
Select this component when migrating from earlier engineering samples or non-cascadable variants like the AWR1243FBIGABLQ1. It provides enhanced performance and cascading support compared to previous generations. Ensure the design requires the specific 161-pin package and integrated MCU architecture for optimal system integration.
Part Context
This part belongs to the Texas Instruments mmWave sensor family. It serves as a production-grade replacement for engineering sample versions such as the ES 2.0 silicon. The XA1243 variant specifically addresses limitations in earlier models by enabling cascading operations for higher resolution sensing.
Replacement Considerations
It replaces the AWR1243FBIGABLQ1 which lacks cascading support. Verify pinout compatibility during migration from older silicon revisions to ensure seamless hardware integration without redesigning the PCB layout.
FAQ
Does the XA1243FPBGABL support cascading?
Yes, unlike the AWR1243FBIGABLQ1, the XA1243FPBGABL supports cascading configurations to increase the number of virtual channels.
What is the primary difference between XA1243 and AWR1243 variants?
The XA1243 variant is a production-grade MMIC that supports cascading, whereas certain AWR1243 variants may not support this feature.
