Using LPC21x for 3-phase AC motor drive Опции

[doomer#gp]

I have taken a look at this series. PWM modules provides 6 single or 3 double front control channels.
But for 3-phase brige it's neccessary 3 PWM outputs with the same quantity of the non-overlaped it inverted outputs.
Could i use LPC series for this purpose anyway ?

Are there a more appropriate MCUs or DSPs for this purpose (must have 6 outputs for 3-phase bridge drive) ?

ADSP21xx from AD, DSP56f8xx form Motorola etc.

ADSP2199x is good, but i wanna find more chiper solution

you have to search MCU for inverter application, like :

i think, Fujitsu has too some MCUs from MB90 family for this purpose.

DSP56f83xx - dream of poet! And inexpensive.

Look at Infineon XC866

OK, thanks to all. I'm gonna research features of the suggested MCU & DSP series.

Check the ADuC702x. They have three phase PWM
