Questions
How big is the Hyperram asic PCB?
It measures 59.5 × 60 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Hyperram asic use?
45 parts, built around the W25Q32JVSSIQ TR, LP5907MFX-3.3/NOPB(MS), S27KL0641DABHI020 and CAY16-22R0F4LF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hyperram asic KiCad files?
From the embelon/hyperram_asic_pcb repository on GitHub, at the commit this page was made from: the board is hyperram_asic.kicad_pcb and its schematic hyperram_asic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hyperram asic design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
