Bosch has announced two new system-on-chips (SoCs), the SX600 and SX601, developed to support a variety of advanced driver assistance system (ADAS) features associated with SAE Level 2+ autonomy. These chips are designed to enable functions such as automatic emergency braking, adaptive cruise control, blind spot detection, and lane change assistance.
Both SoCs incorporate a fully digital phase-locked loop (PLL) for signal accuracy and integration flexibility. The integrated radar receiver supports a high dynamic range, aiming to enhance object detection capabilities across various distances, with reduced error rates compared to previous radar solutions.
Manufactured with 22nm RF CMOS technology, the SX600 and SX601 are built to offer a balance of performance, integration, and cost efficiency. The chips include a millimeter-wave sensor frontend and a digital signal processor for conventional and AI-based data processing. Bosch noted that the design enables support for neural network-based algorithms and can accommodate future system updates.
The SX600 is intended for cost-sensitive applications, while the SX601 provides additional memory and processing capacity. Both chips are interchangeable and support flexible integration with CAN XL and Ethernet interfaces. Each chip includes four transmit and four receive channels and features hardware-based security functions.
For higher system requirements, Bosch offers a cascadable configuration using two interconnected chips. Samples of the SX601 are currently available for development and testing. Bosch also provides an engineering environment to support application development using machine learning tools.
According to the March 2025 Automotive Semiconductor Market Tracker by S&P Global Mobility, the radar semiconductor segment is projected to grow at an annual rate of 12%, faster than the broader automotive semiconductor market.
