1 / 41 page ![]() February 2015 DocID15287 Rev 9 1/41 1 AN2867 Application note Oscillator design guide for STM8S, STM8A and STM32 microcontrollers Introduction Most designers are familiar with oscillators (Pierce-Gate topology), but few really understand how they operate, let alone how to properly design an oscillator. In practice, most designers do not even really pay attention to the oscillator design until they realize the oscillator does not operate properly (usually when it is already being produced). This should not happen. Many systems or projects are delayed in their deployment because of a crystal not working as intended. The oscillator should receive its proper amount of attention during the design phase, well before the manufacturing phase. The designer would then avoid the nightmare scenario of products being returned. This application note introduces the Pierce oscillator basics and provides some guidelines for a good oscillator design. It also shows how to determine the different external components and provides guidelines for a good PCB for the oscillator. This document finally contains an easy guideline to select suitable crystals and external components, and it lists some recommended crystals (HSE and LSE) for STM32 and STM8A/S microcontrollers in order to quick start development. Refer to Table 1 for the list of applicable products. Table 1. Applicable products Type Product categories Microcontrollers STM8S Series STM8AF Series, STM8AL Series STM32 32-bit ARM Cortex MCUs. www.st.com |
