Fast center PWM for Space PWM / BLDC motor

Question asked by bil.til on May 5, 2015
Could anybody give me a hint, which STM32 processor to choose, if I want to get highest possible resolution for centered PWM application (space vector PWM for BLDC motor driving)?

Is this just the standard STM32F407?

I saw the STM32F334 - this has a very fast HiRes Timer with 250 psec resolution, but unfortunately I think there centered PWM does not work (these HRTIM timers run only upwards). So I think this cannot be used for BLDC driving space vector PWM.

... just wondering whether there might hide somewhere some other STM32 controller with a very fast timer mode for space center PWM...
