Fresh and custom silicon day! 😍
This is a multicore riscv soc design based on the serv processor core.
Based on GF180MCU PDK, and fabricated through wafer.space 🚀
I like that the COB is done with clear epoxy on these samples, rather than just a black blob

I'm going to need a bigger zoom... 🤏

@gregdavill@chaos.social Looks great for e.g. a conference badge.

@gregdavill@chaos.social oooooooh, was it really like $4000 worth or did you go on a TinyTapeout?

@gregdavill@chaos.social aren’t they light sensitive, though? Cf Pi’s rebooting under flash photography…

@gregdavill@chaos.social FYI, semiconductors can be light sensitive. I noticed current consumption jumping on a MCU when the microscope light was above the black epoxy case. Photons hitting the junctions has an effect. So when bringing the IC up you can test w/wo a black box encapsulating it.
