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.

@SofLit 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.

Any STM32 having TIM2, TIM3, TIM4 and TIM5 for example, there are many.

STM32F407 as example.
