NXP Unveils Single-Chip Radar SoC Targeting Affordable ADAS Adoption

NXP Semiconductors has announced the SAF8444, an automotive radar system-on-chip (SoC) built on the company's 28nm RFCMOS one-chip architecture. The device is designed to bring advanced driver assistance capabilities to mainstream and entry-level vehicle segments, where cost and complexity constraints have historically limited adoption.

The chip supports L2 and L2+ ADAS functions — including adaptive cruise control, autonomous emergency braking, blind spot detection, and park assist — and operates across the 76–81 GHz automotive radar band for short, medium, and long-range sensing. NXP says the integration of camera and radar data processing directly on the chip reduces reliance on centralised compute resources and can lower a vehicle's overall bill of materials.

Internally, the SAF8444 combines 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. A dual-threaded radar accelerator enables advanced interference mitigation and anti-jamming algorithms — capabilities the company positions as increasingly relevant as radar-equipped vehicle density grows on public roads.

NXP frames the SAF8444 partly as a response to tightening regulatory requirements. Euro NCAP's 2030 criteria call for real-world scenarios such as detecting partially obstructed pedestrians in low-light conditions and maintaining reliable performance across adverse weather. Previously, meeting these requirements typically necessitated additional centralised processing hardware, increasing cost and thermal load.

The company also highlights the chip's suitability for electric vehicle platforms, where thermal management and power efficiency are heightened design concerns. By consolidating radar signal processing on a single chip, NXP says vehicle integrators can simplify system architecture without sacrificing sensor performance.

The SAF8444 is currently in pre-production, targeting next-generation front and corner radar designs. Development support for lead customers is available now. The chip is supported by NXP's radar software ecosystem, including SDKs, safety frameworks, and security components.
