Application note
EMC guidelines for STM8 microcontrollers
Introduction
To meet the demand for higher performance, complexity and cost reduction, the
semiconductor industry develops microcontrollers with both high density design technology
and higher clock frequencies. This has intrinsically increased the potential noise emission
and noise sensitivity. Therefore, application developers must now apply electromagnetic
compatibility (EMC) “hardening” techniques in the design of hardware, PCB layout, firmware
and at system level.
This application note is intended for application designers who need to reach the optimum
level of EMC performance. It gives an overview of microcontroller EMC features and
compliance standards. This document focuses on STM8 features and behaviors, and on the
differences between the STM8 family members.
