Hello ST,The STM32N6 Datasheet (DS14791 Rev 2) claims that the device has 1 HR Timer and 4x 32-bit General Purpose Timers, yet the Functional Overview section does not support these claims. Nor does the Reference Manual (RM0486 Rev 1). Could you pl...

Hello,I would like to know the behavior of the BOOT0 pin on a factory fresh STM32G474 device. I'm wondering if I can use PB6 as a general input without causing side effects if the flash option register is at factory defaults. The reference manual sh...

Hello,I would like to know the process size used in the STM32G4xx. I understand the 'F4, L4 and G0 are 90 nm and the 'H7 is 40nm. My interest stems from an application in a high RF environment, where larger process size would seem to be more robust...

Hello,Can anyone provide a bit of clarity regarding ST's "Marketing Status" terminology? For example, in the STM32CubeMX MCU/MPU selector, I see the following entries for various 'H7 devices:"NA", "Proposal", "Evaluation", "Preview" & "Active". I p...

Hello,I'm hoping to get clarification on the dual-bank flash availability in STM32G47x parts with fewer than 512K of FLASH. The datasheets (DS12288 & DS12712) cover the B, C and E flash sizes. The first page refers to "up to 512KB Flash", yet there...

Hello LCE,Have you considered providing protection ifu32Cycles -= u32CycStart;wraps around? Perhaps that would account for the two consistent values...Regards,Dave

I'll second that! A revision level for peripherals so enhancements can be followed without deep diving into each data sheet during preliminary selection of the MCU. TI does something like this with its Piccolo series...Dave

Hello Adamp,If you're at liberty to change processors, maybe consider the STM32G474 HRTIME1. This timer has amazing flexibility plus you would be on a newer generation series.Regards,Dave

Now that ST is promoting the STM32MP13 as a real-time solution, it would be a logical addition to the Azure licensing list?

Hello Martin,Are you unlocking and writing the option bytes somewhere? After that, they take effect at the next reset or immediately if you "launch" them.Regards,Dave
