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.

On Track for the May MPW Run

As we discussed in a previous update, the next test run of the Open-V chip will take place in collaboration with SiFive as part of their May multi-project wafer (MPW) run. In preparation, we’ve been meeting with the SiFive team every two weeks and we’ve started delivering IP blocks to them. Getting ready for this MPW has been a lot of work, but we’re on schedule and looking forward to the results when they come back in June.

Sponsorship Update

In a previous update, we described the process we’re going through to receive a grant from an interested, credible partner. That situation hasn’t changed much - they are still interested and credible, but they are slow moving. If nothing else, we think the fact the process is still moving at all is a good sign. We will keep everyone posted as soon as we have news one way or the other.

Final Campaign Extension

This is it! We’ve already extended the campaign twice before, though the duration of each extension was arbitrary. We’re going to extend the campaign one more time, and this time the duration of the extension actually means something. In particular, we’re going to extend the campaign until June 30, 2017.

As mentioned above, we’re already racing toward the MPW run, which doesn’t depend on the money from this campaign. We’ll get the results of the MPW back sometime in June, at which point we will need to put into action our plans for actual production, which is where the big expenses covered by this campaign come in.

By June 30, we will either need the money from this campaign to continue the work needed to bring the Open-V chip to production, or we will need to shut down the project or drastically change the production schedule, neither of which would be fair to our backers.

As in our previous campaign extension announcements, we will honor any order cancellations up through the end of the campaign. (No credit cards have actually been charged yet.)

Thanks for all your support. In our next update, we’ll return to our more technical progress reports, or have definitive news about the grant we’re hoping to get.

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.
