Hi,

How many PWM signal pairs is it possible to output with the XMC4300 and with the XMC4800?

Thanks

Hi Lionel,

per CCU4 slice you can generate 1 PWM signal. (No inverted signal)
Each Module has 4 Slices, this means you can generate 4 PWM signals.

per CCU8 slice you can generate 4 PWM Signals (2 + 2 inverted with deadtime)
Each Module has 4 Slices, this means you can generate 16 PWM signals. (8 +8 inverted with deadtime)
(In asymmetric center aligned mode you can generate 4+4 inverted with deadtime)

XMC4800:
- 4x CCU4 Modules: 16 PWM signals
- 2x CCU8 Modules : 32 PWM signals ( 16 + 16 inverted with deadtime)

XMC4300:
- 2x CCU4 Modules: 8 PWM signals
- 1x CCU8 Modules : 16 PWM signals ( 8 + 8 inverted with deadtime)

Due to the reduced pins you can not use the full amount of CCU output pins in the XMC4800 LQFP100.
The XMC Pinout Tool can help you to find the right output pins.

Eric

You could still add the channels by using software-style PWM. But it will be barely necessary I guess.
