STM32 Microcontroller with at least 6 ADCs and advanced PWM with deadtime management

Hi,

Would you please help me to choose a STM32 microcontroller which must have 6 number of ADCs and must be capable of generating PWM signals with deadtime. Thanks in advance.

> must have 6 number of ADCs

6 independent ADC's or just the capability to monitor 6 ADC channels? I'm assuming the latter, which most (all?) chips can do. Don't think any have 6 ADCs. The G4 family has 5.

> capable of generating PWM signals with deadtime

Most families have 1-2 advanced timers.

Those criteria are not very limiting. STM32L4 for low-power, STM32H7 for high performance.
