Which is Best Controller for Speaker design?

sanketkulkarni — Fri, 15 Mar 2019 19:00:35 GMT

I am starting a design for a 2.1 speaker or a 2.0 speaker design. I want to add Wifi and BLE capability to my speaker. I have selected class D amplifier as TDA8954.

But I am confused which controller should I use?

Please help me on the selection of Controller.

I am designing my own PCB. So please suggest a controller and not a board.

Also, my aim is to design a speaker with excellent bass and treble capabilities.

Hi Sanket,

NXP hasn't WIFI chip. KW and QN series device hasn't I2S/SAI interface. You have to use 2 NXP MCU and a WIFI module to build your system. If the master's job is transfer data only, you can use KL16+KW3x. If there is also sound boost/filter algorithm, you can choose K10+KW3x. If you want your system can be extended easily, you can choose RT1015/1020+KW3x.
