Open source release accelerates path to market for commercial CHERIoT-based secure microcontrollers, supporting industry adoption and innovationCAMBRIDGE, United Kingdom, April 02, 2025 (GLOBE NEWSWIRE) -- lowRISC C.I.C., the open silicon ecosystem organisation, together with SCI Semiconductor, a leader in CHERI solutions and both CHERI Alliance founding members, today announced the release of the open source Sunburst Chip design repository, a key milestone in phase two of the DSbD/UKRI-funded Sunburst Project (Grant Number: 107540).
"Our release, with SCI, of the permissively licensed open source Sunburst Chip repository is a significant turning point in bringing CHERI-based security to the embedded systems market, and represents a core deliverable of the Sunburst project.” This news follows lowRISC and SCI Semiconductor’s commitment to tape out the Sonata™ design (incorporating Microsoft's Ibex®-based CHERIoT core).
"We are on a mission to ensure that the market has access to robust, open source foundations for secure-by-design microcontrollers enabling a focus on differentiation, just as we have with Iceni.” The Sunburst Chip repository is now publicly available on GitHub at Developers and researchers are encouraged to explore the repository and leverage the technology for their own CHERIoT-Ibex based designs.
