E7 Series

E76-MC

The SiFive E76-MC Standard Core is a high-performance quad-core 32-bit embedded processor which is fully-compliant with the RISC-V ISA. Its advanced memory subsystem enables inclusion of tightly-integrated memory and caches.

The E76-MC is ideal for applications with high-throughput requirements such as In-storage Compute, Sensor Hubs, Edge-compute Nodes, Biometric Signal Processing, and Autonomous Machines (i.e., Robots, Drones, ADAS systems, etc.)
