1 Introduction

The Hardware Design Guide for AM65x family of Devices Application Report provides a starting point for the engineers designing with AM65x processors. It provides an overview of the flow, design efforts and highlights important areas that must be addressed. Note that this document does not contain all the information needed to complete the system design. In many cases, it refers to the device-specific data manual or to various other user guides as sources for specific information.

The document is organized in a sequential manner. It starts from decisions that must be made during the initial planning stages of the design, through the selection of key devices, electrical, and thermal requirements. For ensuring design success, issues discussed in each of the section should be resolved before moving to the next section.

Note: This guide may not cover every aspect of the system design.
Note:

The AM65x device has capabilities to help system designers address safety requirements.

This guide is focused on non-safety applications.
