NXP Semiconductors has introduced the SAF8444, a next-generation automotive radar system-on-chip (SoC) designed to bring advanced Level 2 and Level 2+ ADAS processing directly onto the sensor, making sophisticated driver assistance technologies more accessible across mainstream vehicle segments.
The new single-chip radar solution features an innovative RF architecture that combines high-performance sensing with improved power efficiency. By integrating advanced radar processing capabilities into a compact SoC, the SAF8444 simplifies system design while helping automakers reduce overall system costs.
The solution also minimizes thermal management requirements and streamlines vehicle integration, enabling manufacturers to develop more efficient and scalable radar systems. These benefits are particularly valuable for electric vehicle platforms, where optimizing power consumption, space utilization, and thermal performance remains a key priority.
SAF8444 builds on NXP’s industry-first 28nm RFCMOS radar one-chip architecture, and paves the way for broad market adoption of advanced L2 and L2+ ADAS functionality in even the most aggressively priced economy class car models and entry-level vehicle lines.
“SAF8444 strengthens our one-chip radar portfolio with a solution that balances performance, power efficiency, and cost,” said Meindert van den Beld, Senior Vice President and General Manager, Radar & ADAS, NXP Semiconductors. “It allows customers to meet tightening safety requirements while reducing system cost—an essential step toward democratizing ADAS adoption.”
Why it matters: As advanced driver assistance features become increasingly required across vehicle segments — and to address Euro NCAP 2030 requirements, which call for real life use cases such as detecting obstructed pedestrians in low-light environments and enabling robust performance in all weather conditions — automakers and Tier 1 suppliers are under increasing pressure to balance performance, regulatory compliance, and cost. SAF8444 addresses these challenges by fusing camera and radar data directly on the chip, which can dramatically reduce system complexity, power consumption, and overall bill of materials.
Meeting higher safety requirements like Euro NCAP 2030 has traditionally meant adding more processing and central compute — driving up cost, thermal load, and architectural complexity. SAF8444 helps break that trade-off by enabling intelligence at the radar sensor itself. By supporting perception level processing directly on the radar SoC, OEMs can reduce reliance on centralized ADAS compute resources, simplify vehicle architectures, and scale compliant ADAS capabilities across more vehicle platforms worldwide.
More details: Manufactured using NXP’s 28nm RFCMOS technology, SAF8444 operates across the 76–81 GHz automotive radar band and supports short, medium , and long range radar sensing. It is optimized for mainstream ADAS functions such as adaptive cruise control, autonomous emergency braking, blind spot detection, and park assist.
The device integrates embedded radar processing, combining an Arm® Cortex®-A53 applications processor, an Arm® Cortex®-M7 real time core, and NXP’s proprietary Single Processing Toolbox (SPT) radar accelerator with DSP support.
SAF8444 integrates a powerful dual threaded radar accelerator supporting advanced radar interference mitigation, and enabling efficient execution of compute-intensive anti-jamming algorithms. As radar density increases on today’s roads, this capability helps ensure reliable operation in congested RF environments — supporting both current deployments and future regulatory expectations.
SAF8444 is supported by NXP’s comprehensive radar software and enablement ecosystem, including radar SDKs, safety frameworks, security components, and development tools designed to accelerate customer development cycles. NXP also provides in-vehicle networking and PMIC solutions, as well as algorithms that empower AI at the network’s edge for robust and highly accurate angle estimation.
Availability: The SAF8444 automotive radar one-chip SoC is announced today and is currently in pre-production, targeting next generation front and corner radar designs. Development support for lead customers is available now.
