S6 Series
S61
The SiFive® Essential™ S61 Standard Core is a mid-range performance 64-bit embedded processor that is fully-compliant with the RISC-V ISA.
The S61 is ideal for latency-sensitive applications in domains such as storage and networking that require 64-bit memory addressability (e.g., general purpose embedded, industrial, IoT, high-performance real-time embedded, automotive).
