The comments on the page are likely correct - CP10356AT. Custom asic or semi custom pd controller for nintendo that supports pd 3.0+, which includes secure vendor-defined messages
The STM32G0B0 is possible but less likely if the CP10356AT is on the pd line, and the STM could coordinate handshake message success
Another scumbag move by nintendo. I hope someone figures out a way to mimic the dock response, dumps the firmware, or emulates it. That’s beyond me but fuck them. Flood the market with $15 clone docks
