Application note
EMC design guide for ST microcontrollers
Introduction
The continuing demand for more performance, complexity and cost reduction require the
semiconductor industry to develop microcontrollers with both high density design
technology and higher clock frequencies. This has intrinsically increased the noise emission
and noise sensitivity. 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 STMicroelectronics microcontroller EMC features and compliance standards to help
application designers reach the optimum level of EMC performance.
