A combination of scalable security, real-time processing, and application processing.
Helps reduce ECU hardware cost, material, and weight with ultra-integrated integration capabilities

NXP Semiconductors has introduced a product that excels in safe, centralized, real-time vehicle control with high-performance deterministic computing that supports the highest level of functional safety.

NXP Semiconductors today announced the S32N55 processor, the first device in its new family of automotive ultra-integrated processors, the S32N.

At the heart of the recently announced S32 CoreRide central computing solution, it provides a scalable combination of safety, real-time processing, and application processing to address the diverse central computing needs of automakers.

Software-defined, hardware-enhanced isolation allows dozens of vehicle functions with different levels of criticality to be hosted, free from interference between functions.

Vehicle propulsion, vehicle dynamics, chassis control, body and other core vehicle functions have been implemented as individual electronic control units (ECUs), each with their own MCU and wiring.

This 'ultra-dense integration' capability allows automakers to significantly reduce the cost of ECU hardware, while also helping with sustainability and extended driving range through reduced materials and weight.

Ultimately, it can significantly reduce the number of ECUs and wiring used by automakers, reducing manufacturing complexity and time.

The S32N55 dynamically partitions resources through its 'core-to-pin' hardware isolation and virtualization technology.

This allows for continuous adjustments, enabling it to be used in an optimal way to meet changing vehicle function requirements.

Hardware-enhanced vehicle function isolation enables automakers to safely integrate ECUs, streamline software development, and support improvements and upgrades throughout the life cycle.

It also enables self-management of vehicle functions, including fault handling and reset, and can receive separate software updates with the S32N55's secure and granular over-the-air (OTA) upgrade function.

“The S32N55 processor is central to our new S32 CoreRide platform’s ability to provide real-time vehicle control, delivering a powerful combination of exceptional real-time performance, key hardware-enhanced isolation and vehicle networking capabilities,” said Ray Cornyn, senior vice president and general manager, automotive processors at NXP. “This enables more functionality with fewer devices, reducing cost and enabling upgradeability to improve and future-proof vehicles.”

Automotive etc.The automotive grade S32N55 processor integrates 16 split-locked Arm® Cortex®-R52 processor cores running at 1.2 GHz for real-time computing.

The cores can operate in split or lockstep mode to support various functional safety levels up to ISO 26262 ASIL D.

A pair of auxiliary lockstep Cortex-M7 cores help manage system and communication, while tightly coupled integrated memory and 48MB of system SRAM enable fast execution with low-latency access.

Additionally, the Hardware Security Engine with firewall provides a root of trust (RoT) for secure boot, security services, and key management.

Memory can also be expanded with LPDDR4X/5/5X DRAM, LPDDR4X flash, and NAND/NOR flash interfaces.

Supports functional safety and security requirements through memory error correction and inline encryption.

It integrates a TSN (Time-Sensitive Networking) 2.5Gbit/s Ethernet switch, a CAN hub for efficient internal routing of 24 CAN FD buses, four CAN XL interfaces, and a PCI Express Gen 4 interface to reduce wiring and system costs.

The S32N55 serves as the central vehicle controller solution for the S32 CoreRide platform and is complemented by NXP’s system power management and vehicle networking devices to accelerate customer designs.

The FS04 safety system power management IC is jointly designed to support ASIL D functional safety.It's been planned.

This, combined with the PF53 scalable core supply for platform design, enables high-efficiency power conversion, low-power mode support, and power sequencing processing.

The S32N55 is currently sampling to key customers.

A robust partner ecosystem, including NXP’s support and the S32 CoreRide software partner ecosystem, includes comprehensive boards, supporting software, tools, and system support to accelerate customer designs.
