I built a microcontroller for high-assurance applications on TSMC 22nm. I call it the "Baochip-1x". Read more about what it is and how it came about at this blog post: https://www.bunniestudios.com/blog/2026/baochip-1x-a-mostly-open-22nm-soc-for-high-assurance-applications/

@bunnie I understand only half of it, but I'm amazed. The thing where I stumble across microchips is audio stuff, Synthesizer, effects -how does it find into that bracket, where at the moment stuff like rp2040, stm32, teensy, electrosmith daisy, ... lives?

@bunnie i did my fair part and subscribed the first batch of the eval board.. drooling waiting..

Way to go.. 22nm is pretty good. What about an "open source" fpga, in the future?

@bunnie is that a play on words, like "bao bun"? cause i did the same thing in ffxiv so imo you're a genius

@xyhhx yep, it's a play on words!

@bunnie i absolutely love that (as well as this project!)
