MPW Run and Final Campaign Extension

We're moving full speed ahead toward a test wafer run, sponsorship to fund Open-V is still a real (if slowly evolving) possibility, and we're extending the campaign one final time, without impacting the main production schedule. Read the full update.

A Taste of Chip Design

As we work at full speed toward the May tapeout to qualify several blocks on 180 nm CMOS, we figured it would be a good time to pause just for a moment to give you a taste of what's required to accomplish this kind of project. Read the full update.

Sponsorship Possibility and 30-day Extension

We're extending the Open-V campaign by 30 days in the hope that by then we will have official sign-off on a grant from a very large organization to provide the remaining funds needed to make the Open-V microcontroller a reality. Read on for details and what this means to backers. Read the full update.

Collaboration with SiFive

Today, we're excited to announce a collaboration with SiFive, a company founded by the creators of RISC-V and dedicated to open source silicon. In the rest of this update, we'll describe the collaboration in detail, what it means for the Open-V microcontroller, and what it means to you, our supporters. Read the full update.

Campaign Extension

To make a long story short, we're extending the Open-V campaign by 45 days and hope to release some exciting news very soon to justify this extension. Read the full update.

Open True Random Number Generator

The Open-V has the potential to greatly boost and democratize hardware security. As a concrete step toward realizing this potential, we’re happy to announce today that the Open-V will include, at no additional cost, a fully open, state-of-the-art, thermal noise-based true random number generator (TRNG) peripheral. Read the full update.

Product Choices


Support Open Silicon!

Thanks for your donation! We'll use it to further push the bounds of open silicon and introduce new features.


Chip Pioneer

Receive one of the first-run Open-V chips. You can mount it proudly for display, or use it in your next project. You'll also receive three stickers commemorating the production of the world's first truly open source microcontroller.


Open-V Dev Board

Everything you need to get started developing for the Open-V microcontroller! This fully assembled board includes a microSD card holder, a micro USB receptacle, two user LEDs, three status LEDs, 32 KB EEPROM, a reset button, 1.2 V and 3.3 V regulators, a JTAG header, a 20-pin expansion port, four mounting holes, and, of course, a first-run Open-V chip. The future is now and this dev board gives you a head start.


Dev Board + Five Chips

Use the dev board (see above) to get started and then jump into your own board designs using the five extra Open-V chips in standard QFN-32 packaging.


Dev Board + 15 Chips

Use the dev board (see above) to get started and then jump into your own board designs using the 15 extra Open-V chips in standard QFN-32 packaging.


Early Access Chip-on-Board

You will receive one of limited edition chip-on-board prototypes from the very next multi-project wafer (MPW) run. Get a head start developing your own project, own a piece of history, and support open silicon all at the same time!


Super Early Access Chip-on-Board

This is one of the limited edition prototypes we've been using for testing development. Get a head start developing your own applications on the Open-V, own a piece of history, and support open silicon all at the same time!


Early Access Chip-on-Board + Design Review

In addition to receiving the early access dev board, you will actually have a seat around the table (via video conference) during the design review process. Ever wanted to learn about the inner workings of IC design? Are you already an expert and want to help guide development? Now's your chance!



With over 30 years of cumulative experience in analog, digital, and RF circuit design, the OnChip team aims to contribute to the growth of the open source community by developing open silicon.
