U6 Series
U64
The SiFive® Essential™ U64 Standard Core is a single-core instantiation of a mid-range performance RISC-V application processor, capable of supporting full-featured operating systems such as Linux.
The U64 is ideal for applications requiring high-throughput, single-thread performance in a power-constrained environment (e.g., general purpose embedded, industrial, IoT, high-performance real-time embedded, automotive).
