SiFive is a fabless semiconductor company that produces computer chips based on the RISC-V instruction set architecture (ISA).[2] SiFive's products include SoCs and development boards.[3]

SiFive is the first company to produce a chip that implements the RISC-V ISA.


SiFive was founded in 2015 by Krste Asanović, Yunsup Lee, and Andrew Waterman, three researchers from the University of California Berkeley.[2][3] On November 29, 2016, SiFive released the Freedom Everywhere 310 SoC and the HiFive development board,[3] making SiFive the first company to produce a chip that implements the RISC-V ISA, although universities have produced earlier RISC-V processors.[3][4]

In August 2017, SiFive hired Naveed Sherwani as CEO.[5] In October, SiFive did a limited release of its U54-MC, reportedly the world’s first RISC-V based 64-bit quad-core CPU to support fully featured operating systems like Linux.[6][7]

In February 2018, SiFive released the HiFive Unleashed, a development board containing a 64-bit SoC with four U54 cores.[8][9]

In April 2018, SiFive received $50.6 million series C funding including a major amount from Intel Capital.[10]


SiFive's business model is based on designing custom computer chips for other businesses.[2][3] SiFive also produces the FE310 microcontroller and development boards.
