E7-A Features

The SiFive Automotive E7-A Series is a 32-bit RISC-V processor family, optimized for performance and efficiency, specifically designed for the Automotive and Functional Safety markets. Building on the robust foundations of the mature SiFive Essential™ portfolio, the multicore capable design of the E7-A Series offers industry best-in-class functional safety support as a Safety Element out of Context to enable use in applications with Automotive Safety Integrity Level (as per ISO 26262) up to ASIL B and ASIL D. 

The E7-AB, targeted at ASIL B integrity levels, employs minimal hardware redundancy of the logic to guarantee safety metrics are satisfied, without the use of Software Test Libraries (STL), enabling faster time to market and minimizing software integration work. 

The finely tuned combination of out-of-the-box features and design scalability ensures designers can achieve the optimal balance of power, performance, and area while achieving the fastest time to market for the 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 an ideal choice for broader deployment in microcontroller applications requiring functional safety capabilities.
