I'm surprised this isn't custom silicon? I thought the U1 chip was required and Apple made?

- detaro 5y agoU1 is only the UWB wireless interface.
- randyrand 5y agoIt likely still includes a small micro thats sufficient. But you need something for the DAC/Speaker and Bluetooth LE, so that may have influenced adding another micro.
- tuankiet65 5y agoSeems like there's an nRF52.
- londons_explore 5y agoKinda surprising Apple uses such a common bit of hardware. What's next - the next MacBook battery controller Arduino controlled?
