Tools: Free Opentitan Shipping In Production 2026

Last year, we shared the exciting news that fabrication of production OpenTitan silicon had begun. Today, we're proud to announce that OpenTitan® is now shipping in commercially available Chromebooks.

The first OpenTitan part is being produced by Nuvoton, a leader in silicon security.

Over the past seven years, Google has worked with the open source communities to build OpenTitan, the first open source silicon Root of Trust (RoT). The RoT is the foundation upon which all other security properties of a device are derived, and anchoring this in silicon provides the strongest possible security guarantees that the code being executed is authorized and verified.

The OpenTitan project and its community are actively supported and maintained by lowRISC C.I.C., an independent non-profit.

OpenTitan provides the community with a high-quality, low-cost, commoditized hardware RoT that can be used across the Google ecosystem and also facilitates the broader adoption of Google-endorsed security features across the industry. Because OpenTitan is open source, you can choose to buy it from a commercial partner or manufacture it yourself based on your use case. In any of these scenarios, you can review and test OpenTitan's capabilities with a degree of transparency never afforded before in security silicon. This allows optimization for the use case at hand, whether it is having multiple reliable suppliers or ensuring the complete end-to-end control of the manufacturing process.

With OpenTitan, we are pushing the boundaries of what can be expected from a silicon RoT. For example, OpenTitan is the first commercially available open source RoT to support post-quantum cryptography (PQC) secure boot based on SLH-DSA. This helps future proof the security posture of these devices against potential adversaries with the capability to break classical public-key cryptography (e.g., RSA) via quantum computing. In addition, by applying commercial-grade design verification (DV) and top-level testing to an open source design, we have pushed for the highest quality while still allowing these chips to be transparent and independently verifiable. An added advantage of this approach is that we expect the high quality IP developed for OpenTitan to be re-usable in other projects going forward.

In addition to delivering this first instance of OpenTitan silicon as a product, we are proud of the processes that we have collaboratively developed along the way. In particular, both individual IP b
