Bosch has introduced two new radar system-on-chip (SoC) solutions, the SX600 and SX601, designed to enhance advanced driver assistance systems (ADAS) with superior object detection and classification capabilities. These next-generation chips target a wide range of SAE Level 2+ automated driving functions, such as automatic emergency braking, adaptive cruise control, blind spot detection, and lane change assist.
Both SoCs operate in the 77 GHz frequency band and incorporate a fully digital, fast-response phase-locked loop (PLL) that enables highly flexible signal output and exceptional resolution. The integrated radar receivers deliver a high dynamic range, allowing the sensors to detect small and distant objects with greater sensitivity and fewer errors compared to conventional radar sensors.
Manufactured using advanced 22-nanometer RF-CMOS technology, the SX600 and SX601 combine a millimeter-wave sensor front end with powerful digital signal processors capable of conventional or AI-based data processing. This results in radar systems with sensing ranges about 30% longer than current market standards. The onboard multicore subsystem provides ample memory and computing power to support customer-specific functions and future scalability.
The SX601 stands out as the most powerful radar SoC available, offering enhanced AI capabilities through neural networks that can classify various objects in real time, such as pedestrians, cyclists, other vehicles, and static objects. This intelligent recognition is especially beneficial for navigating complex urban environments. Bosch also provides a dedicated toolchain to facilitate AI feature development.
Both chips are designed for flexible integration with CAN XL and high-speed Gigabit Ethernet interfaces and include hardware security modules and encryption to protect against unauthorized access and data tampering. The two models share a common form factor and are fully drop-in compatible, allowing easy upgrades without hardware redesign. While the SX600 is optimized for cost-sensitive applications, the SX601 offers higher computing power and greater memory resources. Each supports up to four transmit and four IQ receive channels and can be cascaded for high-end applications needing extended performance. Development samples of the SX601 are already available globally for testing and validation.
With over 25 years of experience in radar semiconductor development, Bosch now directly supplies these SoCs to OEMs and distributors, supporting the ongoing advancement of safer, smarter, and more scalable automated driving technologies.
This launch marks a significant step forward in radar sensor capabilities for ADAS, combining precision, performance, and AI-enabled intelligence to meet the demands of next-generation vehicle safety systems.
