NXP announces latest automotive radar SoC featuring innovative RF design
NXP Semiconductors has announced the SAF8444, a new automotive radar system-on-chip (SoC) featuring an innovative RF design that enables high-performance, power-efficient applications. The solution helps reduce overall system costs by simplifying thermal management for customers and enabling easier vehicle integration. These advantages make it particularly attractive for adoption in electric vehicle (EV) platforms.
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 centralised ADAS compute resources, simplify vehicle architectures, and scale compliant ADAS capabilities across more vehicle platforms worldwide.
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 optimised 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.
