SAF8444 automotive radar system level chip reduces the system cost and design complexity of next-generation ADAS deployment
Latest Updates
NXP Semiconductors announced today the launch of the SAF8444 Automotive Radar System on Chip (SoC) solution. This product adopts innovative RF design, which can achieve high-performance and high-efficiency applications, while also helping customers simplify thermal management design, reduce vehicle integration difficulty, and effectively reduce overall system costs. The above advantages make it more in line with the requirements of electric vehicle platforms for radar assembly rate.
SAF8444 is based on NXP's first 28nm RFCMOS radar single-chip architecture, enabling advanced L2 and L2+level ADAS functions to be widely popularized in affordable and entry-level models.
Meindert van den Beld, Senior Vice President and General Manager of Radar and ADAS at NXP Semiconductors, said, "SAF8444 further enhances our single-chip radar product portfolio, achieving a good balance between performance, energy efficiency, and cost. It helps customers reduce system costs while meeting increasingly stringent safety requirements, which is a key step in promoting the popularization of ADAS.
Significant importance
With advanced driving assistance functions becoming increasingly a rigid demand in various vehicle segments, coupled with the practical usage scenario requirements proposed by Euro NCAP 2030 regulations (such as detecting obstructed pedestrians in low light environments and maintaining robust performance in various weather conditions), vehicle manufacturers and first tier suppliers are facing greater pressure to achieve a perfect balance between performance, regulatory compliance, and cost. SAF8444 addresses the above challenges by directly integrating camera data and radar data on the chip, which can significantly reduce system complexity, power consumption, and overall material costs.
In the past, meeting higher security requirements such as Euro NCAP 2030 typically meant increasing processing power and central computing resources, thereby driving up costs, increasing thermal management loads, and increasing architecture complexity. SAF8444 solves the aforementioned trade-off problem by implementing intelligent processing at the radar sensor end. This chip supports direct perception level processing on radar SoCs, enabling vehicle manufacturers to reduce their reliance on central ADAS computing resources, simplify vehicle architecture, and scale up the deployment of ADAS functions that comply with regulatory requirements on more vehicle platforms worldwide.
More details
SAF8444 is manufactured using NXP 28nm RFCMOS technology and operates in the 76-81GHz automotive radar frequency range, supporting short-range, medium range, and long-range radar detection. This chip has been optimized for mainstream ADAS functions such as adaptive cruise control, automatic emergency braking, blind spot detection, and assisted parking.
This device integrates embedded radar processing capabilities and includes an Arm ® Cortex ®- A53 application processor, one Arm ® Cortex ®- M7 real-time kernel, as well as NXP's proprietary Signal Processing Toolbox (SPT) radar accelerator that supports DSP.
SAF8444 integrates a powerful dual line radar accelerator, supports advanced radar interference suppression functions, and can efficiently execute computationally intensive anti-interference algorithms. With the increasing density of radar on the road, this feature helps ensure reliable operation in congested RF environments, meeting current deployment requirements and providing support for future regulatory requirements.
SAF8444 has received comprehensive radar software and enabling ecosystem support from NXP, including radar SDK, security framework, security components, and development tools, aimed at accelerating customer development cycles. NXP also provides in vehicle network and power management IC solutions, as well as algorithms that empower network edge artificial intelligence to achieve robust and high-precision angle estimation.
Supply situation
The SAF8444 single-chip SoC for automotive radar was released today and is currently in the pre production stage, targeting the design of next-generation forward and angle radar. At present, we can provide development support for our main clients. For more information, please visit nxp.com.cn/saf8444.
