 S32G combines hardware security, ASIL D safety, high-performance real-time and application processing, and network acceleration for service-oriented gateways, domain controllers and safety co-processors.

S32G274A主要特性:

S32G274A目标应用:

Central gateways that require acceleration for deterministic networking and processor offloading and embedded security for emerging over-the-air services

Service-oriented gateways that require high-performance application processing with isolation to rapidly deploy new safe and secure services

Domain controllers that require high-performance real-time and application processing to support ECU consolidation, network protocol translation and local domain control

Safety co-processors that require ASIL D functional safety processing with network connectivity and PCI Express® for data sharing with other components and central mass storage

Designed and manufactured to our proven automotive practices, and with an embedded hardware security engine (HSE), the S32G processor satisfies developers needs for high performance, safety, security and reliability
