XMC4500 - PWM pinout capability at XMC4500 (QFP144)

[forix]

You are wondering how many PWM signals are available at XMC4500.

Here we have a calculation:
CCU8 has 4 slices with one timebase each, each timebase has 2 compares, ie. 8 PWM capable pins, each PWM pin can have a complementary output with deadtime, we have 2 CCU8, ie. 16 PWM capable pins on CCU8x.
CCU4 has 4 slices with one timebase each, each timebase has 1 compare, ie. 4 PWM capable pins, we have 4 CCU4, ie. 16 PWM capable pins on CCU4x.
There are 8 PWM capable pins on our Touch Sense Module one one bit timebase.

Hence we have theoretically 32 capable PWM pins (16bit) + 8pins (8bit).

On XMC4500, we have all CCU8x/CCU4x PWM pins on the 144pin packages.

Please note, additionally there is one System Timer and one RTC timer left for SW timebase.

Hi Bernd,

Very nice explanation. Can you confirm that deadtime is available on all OUT signals, not just CCU80_OUT00/CCU80_OUT01 ?

Thank you
Best regards

Hi Aaron,

The deadtime is available on all the CCU8 output.
There are 2 dead time generators for each channel to provide independent dead time values for rising and falling transitions.

Hi Jackson, thank you very much for the confirmation. The reason for the question is I am unable to get the deadtime working with PWMSP002. Please see post below.

The deadtime is only possible between outputs 0 and 1 or 2 and 3, but not 0 and 3 for example.

Hi Dmitry, thak you very much for the information. I will create the deadtime in my C code instead by offsetting the 2 channel timers from each other and adjusting the pulse widths.

Best regards
Aaron
