Hello, Currently we are using STM32G4A1VET6 MCU in our board and we dont have any high speed application in the board, suppose i dont want to use any crystal/oscillator on these pins, then how these pins should be taken care in our schematic, I checked in the documents regarding thsi but it is not mentioned what to do with these pins if we dont connect any crystal/oscillator how can we terminate or can we use it as GPIO, could you please provide the supporting documents for these?

Hello @Meghna
According to the chapter 9.3.13 of the RM0440 Rev9, When the HSE or LSE oscillator is switched OFF (default state after reset), the related oscillator pins can be used as normal GPIOs.
Best Regards.
