    Hello @AMS12345 and welcome to the ST Community :smiling_face_with_smiling_eyes:.

    The reference manual of this MCU is the RM0385

    Best Regards.

    Thanks for the reply @STTwo-32. Could you able to say that this board is flexible for generating tones for single channel and multiple channel using pwm peripheral, pcm peripheral and TDM peripheral.

    @mƎALLEm  can you suggest me the microcontroller that supports PCM-PWM to generate tones without any audio interfaces like I2S, SAI, DAC or om other. With my frequency need to genearte pcm samples and fed to pwm to generate audio as output.

    PCM-PWM can be generated by any GP timer having PWM output.
