Unlocking smarter automotive storage with Silicon Motion

Silicon Motion’s latest PCIe Gen4 SSD controller is designed specifically for next-generation vehicles, delivering real-time performance, robust data security, and full compliance with automotive safety standards. With ASPICE CL3 certification, SR-IOV support, and ultra-fast 1,600 MT/s throughput, this controller enables the shift toward software-defined and autonomous mobility.

Discover how this industry-leading solution is helping OEMs build safer, more responsive, and more intelligent vehicles.

Vehicles today generate and process more data than ever – from high-definition camera feeds to AI-driven navigation systems. Behind the scenes, that data needs to move fast, stay secure, and be instantly accessible. Silicon Motion’s PCIe Gen4 Automotive SSD controller delivers precisely that, setting a new standard for performance, safety, and reliability in the automotive storage space.

What’s inside

The controller features a PCIe Gen4 x4 interface and eight NAND channels operating at speeds up to 1,600MT/s. This high bandwidth supports real-time workloads across ADAS, infotainment, and the growing range of software-defined vehicle (SDV) applications.

Built-in SR-IOV support allows for up to eight virtual functions, enabling OEMs to isolate workloads and streamline software deployment across subsystems. Multiple namespace support adds flexibility, making it easier to allocate storage for various in-vehicle services – from digital dashboards to autonomous driving systems.

Security is a top priority. The controller includes AES 128/256-bit encryption, TCG Opal compliance, and full self-encrypting drive (SED) capabilities. It also complies with ISO21434, ensuring protection against evolving cybersecurity threats.

Silicon Motion’s 7^th-generation NANDXtend technology boosts endurance and data integrity, making it ideal for demanding automotive conditions. The controller meets AEC-Q100 Grade 2/3, ISO26262 ASIL-B, and IATF 16949 standards, ensuring it performs reliably in safety-critical systems.

What sets it apart

This is the only SSD controller in its class with ASPICE Capability Level 3 certification – a mark of mature, consistent, and high-quality software development. OEMs gain a reliable integration partner and reduce the risk of costly delays or bugs in production.

Our PCIe Gen4 controller leads in performance with up to 1,600MT/s throughput. Competing products typically fall short of this mark, often lacking the bandwidth and advanced virtualisation features that make our controller future-ready.

Our security approach goes further than most. While many controllers stop at basic encryption, we offer a fully integrated, multi-layered protection strategy. Combined with full ISO21434 compliance, it ensures the protection of both vehicle systems and user data.

Crucially, our advanced storage architecture with SR-IOV and namespace support gives manufacturers the tools to design flexible, scalable in-vehicle data systems – perfectly aligned with the shift towards software-defined mobility.

Why it matters

Faster data access improves real-time responsiveness for features like collision detection, adaptive cruise control, and live infotainment. By supporting these functions with low latency and high reliability, the controller enhances driver safety and experience.

Thanks to ASPICE, CL3-certified manufacturers benefit from a shorter development cycle and better product quality. This helps them meet regulatory targets while keeping pace with innovation.

Energy efficiency is also built into the platform, reducing power draw without compromising performance – an essential factor for electric and autonomous vehicles.

Silicon Motion’s PCIe Gen4 SSD controller isn’t just a component – it’s a foundation for the next generation of connected mobility. Backed by best-in-class performance, robust security, and full automotive compliance, it gives OEMs the confidence to build smarter, safer, and more resilient vehicles.
