APPLICATION NOTE
EMC DESIGN GUIDE
FOR ST MICROCONTROLLERS
by Cyril Troise - Microcontroller Division Applications
INTRODUCTION
The continuing demand for more performance, complexity and cost reduction require the sem-
iconductor industry to develop Microcontrollers with both high density design technology and
higher clock frequencies. This has intrinsically increased the noise emission and noise sensi-
tivity. Application developers therefore, must now apply EMC “hardening” techniques in the
design of firmware, PCB layout and at system level. This note aims to explain ST Microcon-
troller EMC features and compliance standards to help application designers reach the op-
timum level of EMC performance.
