The U575 included in that kit has 2 SAI blocks, which I can be configured I2S and PCM. This should cover both a standard codec and a high voltage SLIC interface. You will need to assess the relevant peripherals to ensure they meet the requirements for your application.
The U575 is well tested on our side for HaLow support. It forms a key part of our micro-controller SDK test infrastructure.
Note, that this kit uses a module which is tuned for 902-928 MHz only (Mouser appears to have an error) - so will work for the Americas, Australia and some of Asia.
