Introduction

This application note provides board-level design guidelines for SmartFusion® 2 and IGLOO® 2 devices. The Layout Guidelines for SmartFusion 2 and IGLOO 2-Based Board Design section describes the PCB design. These guidelines must be treated as a supplement to standard board-level design practices.

Good board design practices are required to obtain expected performance from both PCB and SmartFusion 2/IGLOO 2 devices. High quality and reliable results depend on minimizing noise levels, preserving signal integrity, meeting impedance and power requirements.

This document assumes that the reader has a good understanding of the SmartFusion 2/IGLOO 2 devices, is experienced in digital and analog board design, and knows about the electrical characteristics of systems.

Important: The standard uses “Master” and “Slave.” The equivalent Microchip terminology used in this document is Initiator and Target, respectively.
