Automotive TSN ECU

This solution stands out by providing integrated hardware TSN acceleration, including a nanosecond-level timestamp engine and a traffic shaper supporting the 802.1Qbv standard. This ensures sub-microsecond time synchronisation (802.1AS/gPTP), safeguarding critical control data flows. The high-performance Arm® Cortex®-M7 core delivers the reliable real-time processing power required to run complex TSN protocol stacks alongside application tasks.

A key advantage of this solution is the single-chip integration of multiple automotive interfaces, including TSN Ethernet (MAC), multiple CAN FD, LIN, and FlexIO. This enables designers to create real-time gateways or bridges between new in-vehicle TSN Ethernet backbones and traditional vehicle buses like CAN FD, significantly simplifying system architecture.

Built on an automotive-grade foundation, the MCU is AEC-Q100 Grade 1 qualified, incorporates a Hardware Security Engine (HSE), and supports ASIL-B/D functional safety. This provides the necessary reliability and security for in-vehicle networks. Development is accelerated by NXP S32K3 automotive software and development tools, including real-time drivers (AUTOSAR and non-AUTOSAR) and TSN protocol stacks.
