NXP expands 28nm radar one-chip for ADAS in software-defined vehicles

LAS VEGAS, Jan. 09, 2024 (GLOBE NEWSWIRE) — CES – NXP Semiconductors N.V. (NASDAQ: NXPI) announced an extension of its automotive radar one-chip family. The new SAF86xx monolithically integrates a high-performance radar transceiver and a multi-core radar processor. It also incorporates a MACsec hardware engine for state-of-the-art secure data communication over Automotive Ethernet. Combined with NXP’s S32 high-performance processors, vehicle network connectivity and power management, the full system solution paves the way for advanced, software-defined radar.

The highly integrated radar SoC (System-on-Chip) is intended for streaming rich low-level radar sensor data at up to 1 Gbit/s. It helps carmakers optimize next-generation ADAS partitioning for software-defined vehicles, while providing for a smooth transition to new architectures. Additionally, OEMs will be able to easily introduce new software-defined radar features during the lifetime of the vehicle. Over-the-Air (OTA) updates can achieve this.

It also shares a common architecture with the SAF85xx introduced last year and leverages 28 nm RFCMOS performance for significantly improved radar sensor capabilities, compared to prior-generation 40 nm or 45 nm products. It enables Tier-1 suppliers to build more compact and power-efficient radar sensors. Drivers and other road users will benefit from an extended detection range beyond 300 m. This includes more reliable detection of small objects like curb stones, as well as vulnerable road users, including cyclists and pedestrians.

HELLA, a supplier of automotive electronics, will leverage NXP’s SoC family as the foundation for its 7th generation radar portfolio. This includes variants for front, rear, corner, and side radar.

“After initiating our collaboration with NXP on the development of RFCMOS-based radar sensors approximately 10 years ago, we can now look back and confidently say that choosing this collaboration was the right decision. Leveraging NXP’s RFCMOS TEF81xx and TEF82xx automotive radar transceivers, we have become a leading provider of automotive 77/79 GHz corner radar sensors. With NXP’s radar SoC family, we are now prepared to expand our market position and offer radar solutions for all relevant radar-supported functions, up to level 4 automated driving.”Dr. Dietmar Stapel, Vice President, Radar Program Management at HELLA

The new radar one-chip supports NCAP safety functions including emergency braking and blind-spot detection. It also supports advanced ADAS and autonomous driving applications. This includes advanced comfort features for SAE levels 2+ and 3, such as traffic jam assist, highway pilot, and park assist. Additionally, it provides front and rear cross-traffic alerts, as well as lateral and rear collision avoidance.

“Using our new SAF86xx radar one-chip family, OEMs can quickly and easily migrate their current radar platforms to new software-defined vehicle architectures. A network of connected radar sensors with software-defined functions on a dedicated S32R radar processor in a distributed architecture can enhance radar-based perception to support advancements in autonomous driving. That includes 360-degree sensing, more powerful AI-based algorithms and secure OTA software updates.”Steffen Spannagel, SVP and GM, ADAS, NXP Semiconductors

The comprehensive SAF8xxx family featuring the new SAF86xx and SAF85xx can be tailored for individual OEM use cases. It supports a range of sensor outputs, including object data. It also supports point cloud- or range-FFT-level data for smart sensors in today’s architectures. Additionally, it accommodates streaming sensors in future distributed architectures.

Extending NXP’s 3rd generation RFCMOS radar platform

  • Built on the proven RFCMOS automotive radar expertise of NXP, which was the first to ramp to high volume series production and has already shipped tens of millions of units
  • The SAF86xx radar SoC, optimized for streaming sensors and including a Gigabit Ethernet interface and enhanced MACsec security, operates at a highly integrated 76 to 81 GHz.
  • Developed in accordance with the ISO 26262 Safety Element out of Context (SEooC) methodology supporting ASIL Level B, the SAF86xx adheres to ISO/SAE 21434 (as a component-out-of-context) and fulfills the latest security requirements through its HSE security engine.
