Running STM32H725 SPI at higher frequencies

I'm working on my first STM32 project and have an stm32h725rg configured as a SPI master. Ideally, I'm aiming for a clock frequency of 60 MHz but had to slow it down to 12 MHz (the lowest that my sensor can be configured for) after an initial round o...

Resolved! STM32C0 with 5V power as in AN392

Hello, I am a little confused here, AN392 claims to run STM32C0 from a 5V power supply, directly from the main fed RCD dropper with a 5.6V Zener. But the datasheet says the maximum voltage is 4V.So does the AN suggest running way over max specs or is...
