NXP Semiconductors has introduced its third-generation S32R47 imaging radar processors, built on 16nm FinFET technology, promising up to 2x the processing power of its predecessor while enhancing cost and power efficiency.
The launch marks a significant leap in radar processing technology, enabling higher resolution imaging radar essential for advanced driver assistance systems (ADAS) and autonomous driving levels L2+ to L4, as forecasted in Yole Intelligence’s 2024 radar industry report.
Meindert van den Beld, SVP & GM of Radar & ADAS at NXP, “The S32R47 can efficiently process three times or more antenna channels in real time than today’s production solutions. It delivers the resolution, sensitivity, and dynamic range required for next-gen use cases like piloted driving and fully automated parking—while staying within OEM power and cost targets.”
Key Highlights of the S32R47 Platform:
- Built on proven foundations of NXP’s prior two radar processor generations
- Offers AI/ML support for advanced object classification and improved Direction of Arrival (DoA) processing
- Features a 38% smaller chip footprint, making it easier to integrate into compact automotive systems
- Achieves performance parity or better with up to 89% fewer antenna channels, significantly lowering system cost and complexity
- Supports software reuse across NXP’s S32R platform, accelerating development and deployment
- Complies with ASIL B(D) functional safety standards and modern cybersecurity protocols, including over-the-air updates
Designed to generate richer point clouds and enable AI-powered perception systems, the S32R47 allows precise detection of vulnerable road users and small or unexpected objects in complex environments. This enhances the reliability and safety of autonomous features in challenging urban conditions.
As the global push for autonomous vehicles intensifies, NXP’s scalable radar sensing portfolio—ranging from corner radar to high-resolution 4D imaging radar—is positioned to be a key enabler of the next wave in automotive innovation.
