New Delhi: NXP Semiconductors announced the S32N55 processor, the inaugural device in the S32N family of vehicle super-integration processors. As the core of the S32 CoreRide central compute solution, it offers scalable combinations of safe, real-time, and applications processing to meet automakers’ central compute needs. The S32N55 processor specializes in safe, centralized, real-time vehicle control, accommodating high-performance, deterministic computing for maximum functional safety. Through software-defined, hardware-enforced isolation, it can manage numerous vehicle functions independently.
The S32N55 processor enables the consolidation of vehicle functions, reducing ECU hardware costs significantly. This "super-integration" capability decreases material usage and weight, contributing to sustainability and extended driving range. Ultimately, fewer ECUs and less wiring result in lower manufacturing complexity and time for carmakers.
With the S32N55’s hardware isolation and virtualization technologies, its resources can be dynamically partitioned to adapt to evolving vehicle function needs over time. Hardware-enforced isolation enables safe consolidation of ECUs, streamlining software development and supporting lifetime enhancements and upgrades. Vehicle functions can receive independent software updates with the S32N55’s safe, granular Over-the-Air (OTA) upgradeability.
Ray Cornyn, senior vice president and general manager of automotive processors at NXP, stated, “The S32N55 processor is the central brain for real-time vehicle control in our new S32 CoreRide platform. With unrivalled real-time performance, critical hardware-enforced isolation, and vehicle networking capabilities, it can deliver more functionality with fewer devices, reduce costs, and offer upgradeability to improve and future-proof vehicles.”
The S32N55 processor integrates 16 split-lock Arm® Cortex®-R52 processor cores running at 1.2 GHz for real-time computing, supporting different functional safety levels up to ISO 26262 ASIL D. Tightly-coupled integrated memory and 48 MB of system SRAM enable fast execution with low-latency accesses. An integrated Time-Sensitive Networking (TSN) 2.5 Gbit/s Ethernet switch, a CAN hub, and a PCI Express Gen 4 interface help reduce wiring and system cost.
S32N55 is sampling to lead customers, with comprehensive enablement by NXP and a strong partner ecosystem, including the S32 CoreRide software partner ecosystem, to accelerate customer designs.
