STM32WBA50KG I2S Function Pinout

JimRVLock · ‎2024-11-13

The product page shows that the STM32WBA50KG supports I2S for a serial audio interface. I want to connect a Class-D Amp and cannot find any reference to I2S or SAI in the data sheet or programmers reference manual. Does the processor support I2S?

Hello @JimRVLock

As you can see on the top of the page 1646 of the RM0493 Rev 5, the SAI is Available only on STM32WBA54/55xx devices. So, the STM32WBA50KG does not support the SAI/I2S.

Best Regards.

Yes, the STM32WBA50KG includes various communication peripherals, including I2S functionality. This allows it to connect with audio devices such as Class D amplifiers.

Understood and I upgraded to the STMWBA54.

Just to be clear, the data in the product selector is wrong and should be corrected at some point, but it's not a problem at this point {see below screen shot}.

Thank you for the information and quick response to my question.
