NXP unlocks full potential of vehicle data with S32G vehicle network processor
On January 9, 2020, NXP Semiconductors NV (NASDAQ: NXPI) announced the launch of a new S32G vehicle network processor. This processor marks an important turning point in the design and implementation of the vehicle architecture. As the latest product in the NXP S32 processor family, the S32G processor can help the automotive industry shift to high-performance, domain-based vehicle architectures, reduce software complexity, and increase cryptographic security and functional safety. At present, this S32G has been adopted by major global OEMs and plays an important role in service gateways, helping OEMs to transform from auto manufacturers to vehicle data-driven service providers, thereby expanding business opportunities.
In the new data-driven vehicle business in the future, connected cars need to significantly improve computing performance and communication security. The S32G processor securely manages the transmission of vehicle data and protects critical applications from malicious exploitation, thereby elevating automotive network security to a whole new level. S32G is the first time in the world that a traditional MCU and a high-performance MPU with ASIL D functional safety are integrated on a single chip. At the same time, a network communication accelerator is integrated. Compared with the previous single-function chip, the performance has been significantly improved.
As vehicles continue to evolve toward interconnectedness, automation, and electrification, a large number of data-based services will emerge. Supported by NXP's strong secure and reliable processing technology, OEMs have begun researching new business models, such as vehicle usage-based insurance, vehicle health monitoring, and fleet management services.
In addition, S32G is not just a network processor. The unique combination of functions enables it to support the latest ADAS applications, and provides secure and reliable communication functions, significantly improving the overall integration of the vehicle network. "We believe that the unique combination of network communication, computing performance, and functional safety of the S32G processor is a perfect fit for our next-generation ADAS domain controller," said Bernhard Augustin, Audi's autonomous driving ECU development director.
About NXP S32 processor series
The NXP S32 architecture addresses the challenges of future automotive development through a series of architectural innovations designed to enable automakers to bring rich in-vehicle experiences and autonomous driving capabilities to the market faster.
The NXP S32 processor family provides a unified architecture, including high-performance MCUs and MPUs, application-specific accelerators and interfaces, and the ability to provide the same software environment across application platforms. In this software development environment, developers can share costly R & D work to respond faster to changing vehicle architectures and demanding time-to-market requirements. The application platform can provide automotive-grade quality and reliability, as well as ASIL D functional safety performance in multiple application areas of the vehicle.
Key features of the S32G processor
· Computing performance—The S32G processor provides both ASIL D-level MCUs and MPUs, as well as hardware accelerators for network communications, which can reduce the burden on the processor and provide determinism for the complex real-time environment in which the new generation of OEM vehicles are located Network performance to provide value-added services.
Cryptographic security—Like all other S32 platform processors, S32G embeds a high-performance hardware security accelerator and a public key infrastructure (PKI) supported by the hardware security engine (HSE). A firewall HSE is a root of trust that supports secure startup, provides system security services, and protects against bypass attacks.
Functional safety-NXP S32G processors provide complete ASIL D functionality, including the lock-step Arm® Cortex®-M7 microcontroller core and the lock-step Arm Cortex-A53 high-performance core group, enabling automotive safety processors to achieve Higher level of computing power, and support for high-end operating systems and larger memory.
S32G system solution
NXP has introduced the multi-gigabit secure automotive Ethernet switch SJA1110, which is optimized for integration with S32G processors. The new Ethernet switch complies with the latest TSN standards and provides an integrated 100BASE-T1 PHY, hardware-level security features, and multi-gigabit interfaces. NXP combines the S32G processor, SJA1110 switch and VR5510 power management unit to solve the biggest challenges facing vehicle networks today, including scalability, security and high-speed traffic engineering design.
S32G launch and support
The S32G series includes four devices, and the S32G274A is the first product to be launched, and samples are available to major customers today. NXP's support and a strong partner ecosystem provide comprehensive board, software, tools, and system support to accelerate customers' design processes.
