May 2017 DocID15287 Rev 111/431AN2867 Application noteOscillator design guide for STM8AF/AL/S and STM32 microcontrollers IntroductionMany designers know oscillators based on Pierce-Gate topology (hereinafter referred to as Pierce oscillators), but not all of them really understand how they operate, and only a few master their design. In practice, many of them do not even really pay attention to the oscillator design until they realize that it does not operate properly (usually when the product where it is embedded is already being produced). A crystal not working as intended results in project delays if not overall oscillator should receive the proper amount of attention during the design phase, well before moving to the manufacturing phase. The designer must avoid the nightmare scenario of products being returned from Application note introduces the Pierce oscillator basics and provides guidelines for good oscillator design.
