Question

confirmation for the LPTIM present in the STM32C011J6Px

Now I want to know whether the STM32C011J6Px has a Low-Power Timer (LPTIM).
Currently, we are planning to use the STM32C011F6P6 MCU in STOP Mode 2. Since we do not have any external pin interrupt available as a wakeup source, we are planning to use the LPTIM to wake up the system every 1 ms, read one analog value, and then go back to deep sleep again.

I checked the datasheet and found the following list of timers for this series. Can you please confirm whether this is correct, or let me know if I am missing anything?

TIM1 – Advanced-control 16-bit

TIM3 – General-purpose 16-bit

TIM14 – General-purpose 16-bit

TIM16 – General-purpose 16-bit

TIM17 – General-purpose 16-bit

IWDG – Independent Watchdog

WWDG – Window Watchdog

SysTick – System Timer

    Hello @VIGNESH_KUMAR_M 

    I can confirm that the STM32C011J6Px have 1 advanced-control timer (TIM1), 4 GP timers (TIM3, 14, 16 & 17), Systick timer,IWDG and WWDG as you said (no LPTimer)

    PS: you may use the STM32 sidekick chat bot for such a request. I think it will be helpful.

    Best Regards.
