LS400 | Gateway and Domain Controller

Product Positioning

LS400 is purpose-built for next-generation domain controllers (DCU) and zonal controllers (ZCU), combining 500 MHz of real-time compute with functional safety ASIL-D, the highest level defined by ISO 26262. LS400 is more than a compute core: it is a scalable foundation for the move of vehicle E/E architectures toward centralization, and for the longer-term shift to software-defined vehicles (SDV).

Key Specifications

  • Core frequency: 500 MHz (high-performance real-time computing)
  • Functional safety: ASIL-D
  • Availability: engineering samples, Q3 2026.

Typical Applications

  • Domain controllers: centralized control and function consolidation for body, chassis, powertrain and other domains
  • Zonal controllers: local aggregation and actuation-management nodes for zonal architectures
  • In-vehicle gateways: multi-network aggregation, data forwarding and communication management
  • ADAS and automated driving systems: control and coordination nodes requiring higher compute performance and higher safety integrity
  • Key management: in-vehicle secure communication, key management and secure boot (configuration depends on the project)
  • Sensing and monitoring: multi-source sensor acquisition, condition monitoring and system health management
  • Ultrasonic sensing: control and data-processing nodes for in-vehicle ultrasonic systems

Core Technical Capabilities

  • Functional safety by design: LS400 is developed in accordance with the ISO 26262 lifecycle and supports advanced safety mechanisms such as lockstep cores, giving safety-critical functions a high level of diagnostic coverage.
  • 灵活扩展架构：基于 RISC-V 指令集，在提升算力的同时保持与 Ulyss 全系的代际兼容，保护客户软件资产长期复用。
  • 全方位硬件加固：
    • Connectivity: multiple high-speed in-vehicle bus interfaces for domain-control applications.
    • Cybersecurity: integrated secure boot, key management and hardware cryptography provide a solid basis for in-vehicle security.
  • A joint hardware and software ecosystem: a complete RISC-V development SDK and debug toolchain, a pre-integrated MCAL layer, and close alignment with mainstream software ecosystems such as AUTOSAR.

Product Highlights

  • Built for the highest safety integrity: addresses the most demanding safety requirements for gateway and domain-control applications.
  • Investment protection: a single architecture across the portfolio substantially reduces the engineering effort of moving between generations.
  • Ecosystem alignment: pre-integration shortens the path to production and lowers system-integration TCO.
  • Predictable delivery: a supply chain close to our customers supports faster response and delivery.

Software Toolchains and Development Ecosystem

Lysotech develops hardware and software together, and provides a complete software development environment for its MCU products, including:

  • 开发工具链支持 RISC-V
  • Driver libraries and basic software components (SDK)
  • Debug interfaces and trace support
