SiFive, a US-based fabless provider of customised semiconductors, received $50.6m yesterday in a series C round that featured multiple corporates.

SK Telecom, part of diversified conglomerate SK Group, wearable device maker Huami and computer storage vendor Western Digital all participated in the round, co-led by spinout-focused investment firm Osage University Partners, Sutter Hill Ventures and Spark Capital.

SiFive provides customised semiconductors built on Risc-V, an instruction set architecture (ISA), which acts as the conduit between a computer’s software and hardware.
