Highlights

  • New S32R47 processors deliver up to twice the processing power of previous generations
  • The processors enable improved radar resolution, sensitivity, and dynamic range for autonomous driving
  • NXP’s S32R47 meets functional safety requirements for automotive applications, including Level 3 autonomy

NXP Semiconductors N.V. [NASDAQ: NXPI] has introduced its third-generation S32R47 imaging radar processors, designed for the growing autonomous driving market. Built on 16 nm FinFET technology, these processors deliver up to twice the processing power of previous models, with enhanced power efficiency and reduced system cost. The S32R47 is paired with NXP's radar transceivers, power management solutions, and in-vehicle networking components to support advanced autonomous driving systems and meet safety standards such as ASIL B(D).

Imaging radar technology is crucial for the development of autonomous vehicles, especially in the most challenging driving conditions, such as complex urban environments. The S32R47 processors improve radar resolution, sensitivity, and dynamic range, making them well-suited for demanding applications like piloted driving, automated parking, and enhanced driver assistance systems (ADAS).

According to the Status of the Radar Industry 2024 report by Yole Intelligence, autonomous vehicles, including those at Level 2+ and Level 3, are expected to represent 40% of all vehicles by 2029. This shift underscores the need for radar solutions that can deliver higher performance to support these advanced autonomy features.

The S32R47 can process up to three times more antenna channels in real time compared to current solutions, allowing for denser point cloud data and more accurate environmental modeling. This improved data enables AI-based perception systems, enhancing the vehicle's ability to identify and classify objects such as vulnerable road users and obstacles like lost cargo.

NXP’s third-generation radar solutions offer increased scalability and are designed for volume production with optimized bill of materials. The S32R47 processors address key challenges in radar integration, reducing system size, power consumption, and cost.
