Its a fun radio, the Si4844-A10 is another one and it can tune AM as well. I built one for my house that was connected to an STM32 that was connected to the Internet and would let me stream AM radio to my phone. That way I could listen to sports when I was on the road with the "home" announcers :-).
The Silicon Labs folks did a write up on their radio with an Arduino here: https://community.silabs.com/s/share/a5U1M000000knsEUAQ/buil...
