STM32H7 MCU selction: HRTIM with DLL?

Title and content edited: modified MPU by MCU. There is a big differenece between MPU and MCU products

Hi,

we are currently selecting an STM32 MCU.

We need a dual core M7+M4 and so we've spotted STM32H757, so far so good.

Unfortunately we (lately) found out that even if its timer(s) are stated as HRTIM they do not have the DLL feature implemented and do not support high resolution PWM.

So the question is "Is there any ST MCU fullfilling both requirements, M4+M7 and HRTIM with DLL?"

Hello @Tototo and welcome to the ST Community.

The STM32H745/H755/H747/H757 are the Dual core STM32 MCUs that does not include the DLL. the DLL is supported only on the STM32F334, STM32G47x and STM32G48x that are not dual core products.

Best Regards.

Thank you much STTwo-32,

it's not what I wished to hear, but at least it's a clear, simple statement.

Thank you again.
