HSE option

[Jin2]

In our application we are using part no STM32G0KCIU6 of LQFP32 / UFQFPN32 - GP package.in application we are using USB communication there by we also required 16Mhz HSE, but in this package Pin No 2 of MCU has additional options to configure as OSC_IN whether this pin can be configured for HSE requirement?

Hello @Jin2 and welcome to the ST Community.

The pin that you mentioned can be used as an oscillator input pin for HSE Oscillator. You can't use a HSE Crystal since you will need two pins (OSC_IN. and OSC_OUT). Refer to the step 4 of this article: https://community.st.com/t5/stm32-mcus/how-to-use-stm32cubemx-to-configure-hse-high-speed-external/ta-p/49604 to understand the difference between them.

As a conclusion : you can have a HSE on this pin (an oscillator and not a cristal one).

Best Regards.

Thanks!!

Can I use 48Mhz xtal oscillator? It is our requirement. can be possible to tie on 2nd pin of the controller?

Can be possible to use the same or similar this MPN?

I suggest you to take a look at this discussion. It should be really helpful. Also, the only pin that can be used is the OSC_IN we already mentionned.

Best Regards.
