The transition to digital is impacting every aspect of the vehicle, from the bumper to the cockpit, and manufacturers need solutions that are easy to implement, cross compatible and supported today and well into the future. With challenging power budgets there is also a need to extract high-performance in the smallest possible footprint.

 

RISC-V offers the automaker simplicity, security and software flexibility that is supported by a broad industry ecosystem. SiFive takes that one step further with high-end applications and real time processors that bring industry leading performance, with the lowest area and power consumption and tailored to vehicle specific needs for safety, security and performance.

 

The SiFive Automotive  series is designed for a variety of real-time applications from system control to hardware security modules (HSMs) and safety islands.

 

SiFive Automotive E6-A

The SiFive Automotive E6-A Series is a family of 32-bit RISC-V processors that are optimized for area, performance, and efficiency. These processors are specifically designed for the automotive and functional safety markets. The E6-A Series builds on the mature SiFive Essential portfolio and offers multi-core capabilities and industry-leading functional safety support as a Safety Element out of Context. This enables the use of these processors in applications with Automotive Safety Integrity Levels (as per ISO26262) up to ASIL B and ASIL D.

 

The E6-AB, which is targeted at ASIL B integrity levels, uses minimal hardware redundancy to guarantee that safety metrics are satisfied without the need for Software Test Libraries (STL). This enables faster time to market and minimizes software integration work.

 

The E6-A series offers a range of out-of-the-box features and design scalability, allowing designers to achieve the optimal balance of power, performance, and area while also achieving the fastest time to market for automotive microcontrollers, system controllers, battery management systems (BMS), and safety island for SoC markets. In addition to the automotive market, the E6-A series is also well-suited for deployment in other microcontroller applications that require functional safety capabilities.

 

The SiFive Automotive E6-A series offers IP options that are both area and performance optimized for different integrity levels like ASIL B, ASIL D or split-lock, in line with ISO26262. Automotive products are accompanied by complete safety packages that include documentation to accelerate the SEooC integration and, with it, our customers time-to-market. SiFive Automotive products are also compliant with relevant cybersecurity standards, such as WP.29 R155 and ISO21434.
