NXP Semiconductor has unveiled the first member of the S32N family, the S32N55 processor, designed for real-time vehicle control in software-defined vehicles (SDVs). This new processor is a significant step forward in the automotive industry, offering advanced features to meet the evolving needs of modern vehicles.

The S32N55 processor is powered by 16 ARM Cortex R52 real-time microcontroller cores, each running at 1.2GHz. These cores are organized into eight clusters of two, allowing them to operate in lock-step mode for enhanced functional safety. This architecture ensures reliable and precise control over vehicle functions.

One of the key features of the S32N55 is its "core-to-pin" hardware isolation and virtualization technologies. This enables dynamic partitioning of resources, allowing the processor to adapt to changing vehicle function requirements over time. Automakers can consolidate ECUs, streamline software development, and support lifetime enhancements with this innovative technology.

Moreover, the S32N55 supports hardware-enforced isolation of vehicle functions, enabling independent management of various functions within the vehicle. This capability facilitates fault handling, reset procedures, and independent software updates. The processor's safe Over-the-Air (OTA) upgradeability is crucial for SDVs to enhance their functionality continuously.

The S32N55 processor is designed to meet stringent functional safety requirements, supporting different safety levels up to ISO 26262 ASIL D. It features auxiliary pairs of lockstep Cortex-M7 cores for system and communication management, along with integrated memory and system SRAM for fast and low-latency operations. Additionally, a Hardware Security Engine provides secure boot and key management.
