Industry’s First Open-Source SoC Platforms

SiFive recently introduced the Freedom family of system on a chip (SoC) platforms that are built around the open-source RISC-V instruction set architecture, which was developed by the company’s founders at the University of California, Berkeley.

Features and specs:

  • Freedom U500 Series: The Freedom Unleashed (U) family features a fully Linux-capable embedded application processor featuring the world’s most advanced, multi-core RISC-V CPUs, running at a speed of 1.6 GHz or higher with support for accelerators and cache coherency. Designed in TSMC 28 nm, the Freedom U500 platform is well suited for machine learning, storage, and networking applications. The platform also supports standard high-speed peripherals including PCIe 3.0, USB 3.0, Gigabit Ethernet, and DDR3/DDR4.
  • Freedom E300 Series: The Freedom Everywhere (E) family is designed for embedded microcontroller, IoT, and wearables markets. Designed in TSMC 180 nm and architected to have minimal area and power, the Freedom E300 platform features efficient RISC-V cores with support for RISC-V compressed instructions that have been shown to reduce code size by up to 30%.

Full FPGA models of each SoC are now available. Visit dev.sifive.com for more information.
