Hi everyone,

I'm designing my first STM32 design using STM32F103C8and wondering if I can use 2 Ceramic resonators instead of oscillators as shown in my schematic.

thanks in advanced!

    Hi @TAlle.1​ 

    Yes, you can use ceramic resonator instead of oscillator.

    As mentioned by @Uwe Bonnes​, you can refer to application note AN2867 "Oscillator design guide for STM8AF/AL/S, STM32 MCUs and MPUs". Along of this document you will find how to select a suitable resonator for your MCU, a not exhaustive list of recommended resonators, PCB design guidelines...

    Have a look at AN2867
