1 Introduction

The AM62x (AMC) is an extension of the low-power, low-cost Sitara Industrial/Auto grade family of processors. The AM62x (AMC) is based on the Cortex-A53 microprocessor, M4F microcontroller with dedicated peripherals, 3D graphics acceleration, dual display interfaces, and extensive peripheral and networking options for a variety of embedded applications. The AM62x (AMC) is available in a 17.2-mm × 17.2-mm FBGA package with a 0.8-mm ball pitch. The package BGA design is built leveraging TI Flip Chip BGA Technology (FC-BGA) technology. This document is intended to provide a reference for escape routing on the AM62x (AMC) device. Care must be taken to route signals with special requirements such as DDR and high speed interfaces. Refer to the High-Speed Interface Layout Guidelines and DDR Routing Guidelines for more details. Details on Power Delivery Network are provided in AM62x PDN Application note and any routing and layout requirements specified in those documents supersede the generic requirements provided here.
