M4 with I2s

Calum,

You can filter on that peripheral if you use the "Add/Hide Parameters" button at the top left of the product search table. That said, we do not have any M4 devices that have an i2s peripheral.

However, we do have an app note that reviews how to emulate i2s on the M4 devices using two spi peripherals!

Hope that helps.

And just as a reminder, TI offers plenty of great ADC solutions :-)

PCM1804: 112dB SNR Stereo ADC with Differential Inputs

PCM4202: 118dB SNR Stereo Audio ADC

Thanks - That explains why I couldn't find one!!

Are there any plans to add I2S on future devices?

Hello Keegan

I see this app note, but can I get a data rate on it as well?

Thank you

Elush,

What specifically are you looking for? The clock rate of the codec is determined by the clock input and the PLL settings of the codec. From the app note, the following common sample rates are supported:

- Codec sample rate (8 kHz, 11.025 kHz, 16 kHz, ... , 64 kHz )

- Fsref (44.1 kHz, 48 kHz)
