How many PWM effective outputs does STM32G474RE have???

Hi all,

Thanks in advance for your time

regarding the specific microcontroller STM32G474RE which has a total of 64 pins. How can I know how many of them can be used as PWM outputs???

Thank you

Use StCubeMX to find out. Select the Chip and add PWM function.

I've done it and found out why an exact number is not given in the datasheet... tens of functionalities collide in the same pin and its a mess!! But now I've got the number I was looking for. Thank you very much!!!

Or look at the pin table in datasheet, "PWM output" are timer channels.

They may however collide with other needed system function, so the pure number is not enough, only the number of PWM remaining after other needed pin are also observed.
