Part Number: TM4C1230C3PM
Other Parts Discussed in Thread: TM4C123AE6PM

Hi champs,

customer need approx. 13bit PWM resolution (~10000steps) @  ~25KHz frequency .

How can we achieve this with a TM4C123x device ?

    Hello DJ-NG,

    With the Timer peripheral, that device can support 16-bit PWM mode with an 8-bit prescaler, so 13-bit resolution is possible. They would need to use the Timer module however and so depending on their requirements they may be lacking features since it is a very basic PWM. If they want a dedicated PWM module then they should consider something like TM4C123AE6PM.
