Efinix Released 64-bit RISC-V Embedded Processor Core
The Sapphire RV64 SoC brings expanded memory and Linux support to embedded FPGA designs.
Updated on Sept. 28, 2026 in Semiconductors
Efinix has announced the Sapphire RV64 SoC, a 64-bit processor core designed for its Titanium, Topaz, and Trion FPGAs. This new core enables higher performance for embedded applications that exceed the memory limits of existing 32-bit cores.
Why it matters
The transition to 64-bit architecture allows developers to deploy more complex software and larger memory footprints on field-programmable hardware. This development addresses the performance bottlenecks commonly found in smaller embedded systems as they scale in data requirements.
The Sapphire RV64 SoC features a seven-stage pipeline and supports memory controllers for DDR3, HyperRAM, and LPDDR4x at speeds up to 3,200 Mbps. It includes an optional SV39 memory management unit to support Linux operating systems.
The players
Efinix
A developer of FPGA technology known for its small-footprint programmable logic silicon used in embedded computing.
The details
Engineers configure the SoC core through the Efinity IP Manager to optimize it for Titanium, Topaz, or Trion FPGA platforms. The design incorporates the RISC-V instruction set architecture, the fundamental rules that define how software communicates with the processor hardware. Debugging and software development are managed via the proprietary Efinity RISC-V Embedded Software IDE.
Timeline
September 28, 2026: Efinix announced the availability of the Sapphire RV64 SoC.
The Tech Race
This release positions Efinix alongside competitors integrating the open-standard RISC-V architecture into programmable logic. The move directly competes with established embedded platforms that have historically relied on 32-bit architectures for local processing tasks.
Developers working with Titanium, Topaz, and Trion T20 (and above) FPGAs can immediately begin using the new core in their design workflows. The platform requires using the Efinity IP Manager for configuration and the Efinity RISC-V Embedded Software IDE for software development.
The takeaway
The move to 64-bit processing in embedded FPGAs signals a shift toward handling more demanding data loads at the edge. Developers should monitor Efinix for future updates to the Efinity software suite that might enable broader peripheral support for these 64-bit cores.
