1 Introduction

The AM263x and AM263Px devices are single, dual or quad-core Arm® Cortex®-R5F based MCUs in the Sitara™ MCU family intended for the industrial and automotive motion control environments. A typical AM263x or AM263Px-based design with a discrete power solution is shown in Figure 1-1. This diagram is excerpted from the AM263x Launchpad (LP-AM263) system block diagram. A typical AM263x- or AM263Px-based design with a PMIC (Power Management Integrated Circuit) based power solution is shown in Figure 1-2. This diagram is excerpted from the AM263Px controlCard (TMDSCNCD263P) system block diagram. As can be seen below, the AM263x and AM263Px devices offer designers a wide range of digital connectivity, control and analog sensor feedback options with multiple power solutions supported.
