32bit MCU recommend for DMM and audio analysis

Xing Ou

Hi Team,

We need a MCU for new design which include DMM and audio play and analysis founction, and need some interface like I2C/I2S/UART/SPI.

Would you please help to recommend some 32bit MCU?

Best Regards!

Hi,

I think the TI ARM processor product page will be a good starting point for search the various TI processors supporting the mentioned interfaces (I2C/I2S/UART/SPI). TM4C123x and TM4C129x are two general purpose MCU that you can consider.

Hi Charles,

Thanks for your kindly replyed and recommended. But I found that most TI MCUs do not have an I2S interface. Please help provide some solutions to connect to CODEC/DAC, or can I use other interfaces instead of I2S to transmit audio signals？

Best Regards!!

Hi Xing,

You can emulate I2S with a dual channel SPI. Please refer to this app note for TM4C123. The TM4C129 can do the same implementation as well.
