AN80994 - PSoC® 3, PSoC 4, and PSoC 5LP EMC Best Practices and Recommendations

AN80994 provides recommendations and best practices for improving the EMC performance of designs based on PSoC® 3, PSoC 4, and PSoC 5LP. This application note also details the requirements to pass IEC 61000-4-2 electrostatic discharge (ESD) immunity tests and IEC 61000-4-4 electrical fast transient (EFT) and burst immunity tests.

Introduction

This application note gives engineers the information they need to use Cypress PSoC® 3, PSoC 4, and PSoC 5LP devices to build and test electromagnetic compatibility (EMC)–compliant electronic devices. Included are recommendations to the schematic and PCB designers that help meet EMC specifications. Cypress designed an experimental test board and tested it to provide examples of how to build electronic devices that meet the electrostatic discharge (ESD) and electrical fast transient (EFT) EMC requirements. This application note also presents those test results.
