Open to the core

lowRISC is a not-for-profit company with a full stack engineering team based in Cambridge, UK. We use collaborative engineering to develop and maintain open source silicon designs and tools.

OpenTitan® Partnership Makes History as First Open-Source Silicon Project to Reach Commercial Availability

Definitive Project Success is Result of Five Years of Strong Collaboration and Investment by the OpenTitan Coalition to Bring First Trustworthy, Transparent, Secure Silicon Platform to Market CAMBRIDGE, England – February 13, 2024 – lowRISC C.I.C., the open silicon ecosystem organization, and the OpenTitan coalition today announced a historic milestone as the first open-source silicon project to reach commercial availability, with validated chips in hand. The capstone moment is the result of an unprecedented amount of support and investment by the nine coalition members, including Google, Winbond, Nuvoton, zeroRISC, Rivos, Western Digital, Seagate, ETH Zurich and Giesecke+Devrient, hosted by the non-profit lowRISC CIC.

Announcing OpenTitan, the first transparent silicon root of trust

We are excited to unveil the OpenTitan silicon root of trust project, a new effort built using the successful collaborative engineering model created by lowRISC in partnership with Google and other commercial and academic partners.

This effort sets a new bar for transparency in trusted silicon, and lowRISC is proud to serve as both steward and not-for-profit engineering contributor to OpenTitan, the world’s first open source silicon root of trust.

Silicon root of trust chips increase trust in the integrity of the infrastructure on which software runs. Open sourcing the silicon design makes it more transparent, trustworthy, and ultimately, secure.
