Introduction

Continual demand is placed on the semiconductor industry for increased microcontroller performance and complexity, as well

as cost reduction. This requires the development of microcontrollers with both high-density design technology, and higher

clock frequencies. These factors have intrinsically increased the noise emission and noise sensitivity of microcontroller devices.

Application developers must therefore now apply EMC "hardening” techniques in their firmware design, PCB layout, and at

system level.

This application note explains the microcontroller EMC features and compliance standards to help application designers reach

the optimum level of EMC performance.
