Real-time Vehicle Control with NXP's S32N55 Processor
S32N55 Processor: Enabling Real-Time Central Vehicle Control
On April 9, 2024, NXP® Semiconductors N.V. announced the launch of the S32N55 microprocessor chip, the first product in the S32N series of ultra-high integrated vehicle processors. S32N55 As the core of the S32 CoreRide central computing solution, it provides a scalable combination of security, real-time and application processing designed to meet the diverse central computing needs of automakers.
S32N55 Processor: Core Features
S32N55 processor excels in safe, centralized, real-time automotive control, supporting high performance and deterministic computing capabilities required for the highest levels of functional safety. Through software-defined hardware-enforced isolation, S32N55 can host dozens of automotive functions with different levels of importance while avoiding interference between different functions.
S32N55 Processor: Technical Specifications And Safety Features
1. The automotive-grade S32N55 processor integrates 16 Arm® Cortex®-R52 processor cores in split-core lockstep, running at up to 1.2GHz for real-time computing.
2. Supports functional safety up to ISO 26262 ASIL D, and can run in split-core mode or lockstep mode.
3. Two auxiliary lock-step Cortex-M7 cores support system and communication management.
4. Tightly coupled integrated memory and 48MB of system SRAM ensure fast execution and low-latency access.
5. Firewall-protected hardware security engine provides a root of trust for secure boot, security services and key management.
S32N55 Processor: SDV Integration And Cost Optimization Achieved
Traditional automotive powertrain, chassis control, body and other functions are usually implemented through independent electronic control units (ECUs), but now these functions can be safely integrated into the S32N55 processor, realizing the integration of software-defined vehicles (SDV). This "ultra-high integration" capability enables automakers to significantly reduce ECU hardware costs, reduce materials used and weight, thereby improving sustainability and mileage. In addition, fewer ECUs and significantly reduced wiring also help reduce manufacturing complexity and shorten manufacturing time.
S32N55 Processor: Expansion Capabilities And Network Functions
1. Memory expansion:S32N55 processor supports expansion through LPDDR4X/5/5X DRAM, LPDDR4X flash memory and NAND/NOR flash memory interfaces, while built-in memory error correction and inline encryption functions to meet the needs of functional safety and information security.
2. Network functions:Integrated time-sensitive networking (TSN) 2.5Gbit/s Ethernet switch, CAN hub for efficiently routing 24 CAN FD buses internally, 4 CAN XL interfaces and 1 PCI Express Gen 4 interface, effectively reducing the overall cost of wiring and system.
As a third-party international chip trading company, we are honored to introduce how the S32N55 processor released by NXP complements NXP's system power management and car networking devices to form the automotive central controller solution of the S32 CoreRide platform. This integrated solution helps our customers accelerate the design process and achieve faster time to market. The FS04 safety system power management IC is co-designed to support ASIL D functional safety, ensuring the reliability and safety of the system under extreme conditions. Combined with the PF53 scalable core power supply for platform design, it provides efficient power conversion, supports low power modes, and properly handles power startup timing, further improving the energy efficiency and reliability of the system. This tight ecosystem integration ensures that the S32N55 processor can achieve high-performance, safe and reliable central real-time control in software-defined vehicles (SDVs).
