NXP Semiconductors enables the implementation of Advanced Driver Assistance Systems (ADAS) in entry-level vehicles through a new automotive radar system-on-chip (SoC).

NXP announced the 'SAF8444' automotive radar SoC on the 10th. This product is designed with a 28nm RFCMOS-based one-chip architecture.

The SAF8444 features a structure that performs data processing and recognition functions directly within the radar sensor itself. This approach reduces dependence on a central computing unit and simplifies the vehicle system configuration.

The product is designed to directly fuse camera and radar data within the chip. The company explained that this structure is used to reduce system complexity, power consumption, and component costs.

In addition, it integrates an Arm Cortex-A53 application processor, a Cortex-M7 core, and a DSP-based radar accelerator to support real-time processing at the sensor level.

The SAF8444 operates in the 76–81 GHz automotive radar band and is applied to adaptive cruise control, automatic emergency braking, blind spot detection, parking assist functions, etc.

In particular, it is characterized by being designed to enable Level 2 and Level 2+ ADAS functions to be applied even to entry-level vehicles.

Recently strengthened safety standards were also cited as a background for product development. Regulations such as Euro NCAP 2030 require real-world performance, including pedestrian recognition in low-light environments and response to adverse weather conditions.

The company explained that while existing methods relied on increasing central computing resources to improve performance, the SAF8444 takes an approach that reduces costs and heat issues by performing processing functions at the sensor level.

The SAF8444 is equipped with a dual-threaded accelerator that includes radar interference mitigation capabilities. This enables stable operation even in environments where multiple radars are used simultaneously.

It also provides a software ecosystem, including radar SDKs and development tools.

The product is currently in the pre-mass production phase, and development support for key customers is underway.
