STM32N645B0: TIM8 not available

Thomas_N · ‎2025-10-27

Hello Community,

I have tried to configure TIM8 in CubeMX (Version 6.15.0) with device STM32N645B0 (VFGBA198). But TIM8 is not available in the Timers Group. All other timers are displayed, only TIM8 is missing.

Also trying to activate TIM8 over the pin directly does not work.

Any ideas?

Best regards

Thomas

Hello @Thomas_N

Thank you for posting!

Actually, after checking, as mentioned in DS14791 Rev. 7, only one Advanced Control Timer is supported for this part number, in this case only TIM1 is supported.

Hello @Thomas_N

The STM32N645B0 have only 1 advanced control timer (TIM1):

so, the TIM8 does not exist on the STM32N645B0.

Best Regards.
