"The HiFive board is intended to drive demand for custom SoCs SiFive will design and comes with a growing pool of open source Linux variants and tools fed by an expanding foundation that maintains the RISC-V instruction set."
"Choice is always a good thing, and now SiFive, a fabless semiconductor company, has released the HiFive1 as a crowdfunding campaign on CrowdSupply. The heart of the HiFive1 is SiFive’s FE310 SoC, a 32-bit RISC-V core running at 320+ MHz."
"By contributing the FE310 RTL code to the open-source community, SiFive said it aims to encourage open-source development of both software support for RISC-V as well as other open hardware development."
"The FE310 is the first member of the Freedom Everywhere family of customizable SoCs designed for microcontroller, embedded, Internet of Things, and wearable applications."
"SiFive is on a mission to encourage open-source development of both software support for RISC-V as well as other open hardware development... SiFive’s “chips-as-a-service” offering can customize the FE310 to meet [developers'] unique needs."
The HiFive1 is an Arduino-Compatible development kit featuring the Freedom E310, the industry’s first commercially available RISC-V SoC.
The Freedom E310 (FE310) is the first member of the Freedom Everywhere family of customizable SoCs. Designed for microcontroller, embedded, IoT, and wearable applications, the FE310 features SiFive’s E31 CPU Coreplex, a high-performance, 32-bit RV32IMAC core. Running at 320+ MHz, the FE310 is among the fastest microcontrollers in the market.
Additional features include a 16KB L1 Instruction Cache, a 16KB Data SRAM scratchpad, hardware multiply/divide, a debug module, flexible clock generation with on-chip oscillators and PLLs, and a wide variety of peripherals including UARTs, QSPI, PWMs, and timers. Multiple power domains and a low-power standby mode ensure a wide variety of applications can benefit from the FE310.
The FE310 is the first open-source RISC-V SoC available in industry. SiFive has contributed the FE310 RTL code to the open source community. That means you can see what’s inside the chip and completely understand how the hardware works.

By releasing the RTL code, SiFive wants to encourage open source development of both software support for RISC-V as well as promote open hardware development.
The RTL code also empowers chip designers with the ability to customize their own SoC on top of the base FE310. For system architects, developers, or companies without chip design capabilities, SiFive’s “chips-as-a-service” offering can customize the FE310 to meet their unique needs.
Unless you had millions of dollars to spend, the dream of getting custom silicon was just that – a dream. With the end of conventional transistor scaling and escalating chip design costs, the silicon industry is no longer able to serve the fragmented market and the needs of the next generation of innovators.
At SiFive, we believe that by bringing the power of open-source and agile hardware design to the semiconductor industry, we greatly reduce the cost to harness the performance and energy-efficiency of custom silicon to the smallest company, inventor, or maker.
SiFive’s “chips-as-a-service” is meant for you – the system architect, developer, inventor, creator, and dreamer.
Do you want to write your own RTL? Download the open-source RTL to FE310 and connect your accelerator or peripheral right into the SoC and prototype it on our FPGA dev kits (available separately at dev.sifive.com. Then contact us about how we can quickly deliver an affordable sample of your custom chip and then take you to production by delivering packaged, tested chips.
Or, if you simply know what you want, we can customize the FE310 to meet your unique needs. No RTL needed. So play around with the HiFive1, develop some software, figure out what more you need in your version of the FE310.
Either way – come talk to SiFive. We can make and deliver your own custom chips based on the FE310 for much less than you’d probably pay just to license a different CPU core. Learn more about chips-as-a-service at www.sifive.com.
Perfect! This board is the first RISC-V based development kit in the market. As you can expect from SiFive and the inventors of RISC-V, the FE310 supports the latest RISC-V specifications as of Nov 27, 2016:

We do plan to make the individual Freedom E310 chips available, but currently the only thing available is the Hifive1 board. There are some additional complexities associated with providing chips and support that we are working through. Please stay tuned for an update!
SiFive has launched and demoed the first set of HiFive1 dev kits and Freedom Everywhere 310 SoCs at the 5th RISC-V Workshop held on November 29, 2016.
To get these dev kits to everybody as soon as possible, we are expediting our next manufacturing build. These limited run boards will be known as “HiFive1 Founder’s Edition” and will come with a special silkscreen featuring the signatures of the Founding Team at SiFive, and will be slightly more expensive than the production boards but will ship in December 2016.
The standard HiFive1 dev kits will be available by early February 2017.
Please note that these boards and chips are Engineering Samples, and are intended for development use only.
