NXP pioneers 28nm RFCMOS radar single-chip family to help build ADAS architectures for software-defined vehicles

Views : 27
Update time : 2024-01-20 09:39:19
        NXP Semiconductors N.V. (NASDAQ: NXPI) today announced a new family of automotive radar single-chip products. The new SAF86xx single-chip integrates a high-performance radar transceiver, a multi-core radar processor and a MACsec hardware engine for advanced secure data communication over automotive Ethernet. Together with NXP's S32 high-performance processor, in-vehicle network connectivity and power management, this complete system solution paves the way for advanced software-defined radar.
 
 
        The highly integrated radar SoC (system-on-chip) is expected to be able to stream large amounts of low-level radar sensor data at 1Gbit/s (maximum), helping automotive manufacturers optimize next-generation ADAS partitioning for software-defined vehicles while supporting a smooth transition to new architectures. Additionally, OEMs can easily add new software-defined radar functionality via over-the-air remote upgrades (OTAs) during the vehicle's lifecycle. 
        It also utilizes the same general-purpose architecture as the SAF85xx released last year, and its 28nm RFCMOS performance provides a significant increase in radar sensor capability compared to previous-generation 40nm or 45nm products.Tier 1 suppliers can build more compact, energy-efficient radar sensors with this new product. The detection range extends beyond 300m, enabling more reliable detection of small objects such as curbs and vulnerable road users such as cyclists and pedestrians, bringing more comprehensive and efficient safety to drivers and other road users.
        HELLA, a leading supplier of automotive electronics products, will develop its seventh-generation radar product portfolio (including different versions of front radar, rear radar, corner radar and side radar) based on NXP's SoC family of products," said Dr. Dietmar Stapel, HELLA's vice president and radar program manager, "We started to develop our RFCMOS-based radar products in cooperation with NXP about ten years ago. We started working with NXP about ten years ago to develop RFCMOS-based radar sensors, and looking back now, we can confidently say that we made the right decision to work with NXP. With NXP's RFCMOS TEF81xx and TEF82xx automotive radar transceivers, we have become a major supplier of automotive radar sensors for 77/79 GHz angles. With NXP's radar SoC family, we now plan to strengthen our market position with radar solutions for all radar-supported and relevant functions, even Level 4 autonomous driving."
        The next-generation radar single chip supports NCAP safety features, including emergency braking and blind spot detection. It also supports advanced ADAS and autonomous driving applications, including SAE Level 2+ and 3 advanced comfort features such as traffic congestion assist, high-speed cruise and park assist, forward and rear cross traffic warning, and lateral and rear collision avoidance. 
        With NXP's new SAF86xx radar single-chip family, OEMs can easily and quickly migrate their current radar platforms to the new software-defined automotive architecture," said Steffen Spannagel, senior vice president and general manager of ADAS at NXP Semiconductors. Radar sensors with software-defined capabilities connected into a vast network and using a dedicated S32R radar processor in a distributed architecture can enhance radar-based sensing capabilities to support the development of autonomous driving technologies. This includes 360-degree sensing, more powerful AI algorithms and secure OTA software updates."   
        The comprehensive SAF8xxx family includes the new SAF86xx and SAF85xx, which can be customized for individual OEM use cases. It supports a range of sensor outputs, including object, point cloud or distance FFT-level data from edge computing sensors in today's architectures and distributed streaming sensors in future distributed architectures.
