For a project, i need 7 32bits timers (clk around 8MHz ) : - 4 output generate (1 signal, 3 interruptions) - 3 input capture I expect to use 32-bits timers (TIMER15 and 16) . is it OK with STM32H753 ? Regards

Most timer in STM32 are 16-bit, with 16-bit prescaler, does that count as 32-bit?

TIM15 has only two channels, TIM16 only one. An overview of timers in STM32 families is in AN4013, details are in TIM chapters of STM32H7xx RM.

sorry for my errors : as seen in AN4013 document (page 7), i expect to use TIM2 and TIM5. My need is 32 bits counters, because of the frequency (8MHz min) and duration (at least 500ms). The question is about the number of channels in these timers and the capability to have TIM2 and TIM5 fully synchronized (same count at same time).

All timers except tim2 and tim5 are 16 bit. Both timers have 4 channels. meets the number of IOs you want. I hope you will not have any problems while managing the timers in practice.

Many thanks to all, i have the answer, so we may carry on using ST device.
