Introduction

This application note provides guidance on how Microchip secure element devices can be effectively used as building blocks in the creation of ISA/IEC 62443-compliant products.

This document is targeting engineers and managers tasked to obtain ISA/IEC 62443-compatible or certified products.

In the context of ISA/IEC 62443, Microchip components ATECC608 and TA100 can be acknowledged as technology enablers on the path to reaching compliance and certification of Industrial and Automation Control System (IACS) products according to the standard (with specific reference to part 62443-4-2 of the all-encompassing ISA/IEC 62443 standard: “Technical Security Requirements for IACS components”), as clarified in this document.
