Resolved! STM32H7 USB VBUS sensing question

I am using the USB OTG FS on the STM32H7. My MCU is self powered, so I need to use VBUS sensing. Can a 3.3V signal be used for the VBUS sensing on PA9 or must it be 5V? Based on the linked forum, I believe 3.3V would work, but would like to confirm w...

ADC Data extraction at high sampling frequency

ST moderator: Edited the tile to add "ADC" I want to extract data at high sampling frequency ~10KHz at STM32N6570-DK, Is it possible with USART for three channels or we have any other mode for this purpose. I want to continuously stream data at 10KHz...

STM32N6 XIP with Quad spi

We have both a very RAM constrained and space constrained board.  So the OctoFlash chips are larger then i would like.   So being able to XIP off a spi flash that only has 4 SPI lanes would be very helpful.  I just don't know the ramifications of som...
