1 Introduction
The DRA72x evaluation module (EVM) is an evaluation platform designed to speed up development
efforts and reduce time to market for applications such as infotainment, reconfigurable digital cluster or
integrated digital cockpit. To allow scalability and re-use across DRA72x Jacinto Infotainment SoCs, the
EVM is based on the Jacinto 6 Eco DRA718 SoC that incorporates a heterogeneous, scalable architecture
that includes a mix of an ARM®Cortex®-A15 core, two ARM Cortex-M4 processing subsystems, one C66x
Digital Signal Processors (DSPs), 2D- and 3D-graphics processing units including Imagination
Technologies POWERVR™ SGX544 and a high-definition image and video accelerator. It also integrates
a host of peripherals including multi-camera interfaces (both parallel and serial) for LVDS-based surround
view systems, displays, CAN and Gigabit Ethernet AVB.
The main CPU board integrates these key peripherals such as Ethernet or HDMI, while the infotainment
application daughter board (JAMR3) and LCD/TS daughter board will complement the CPU board to
deliver complete system to jump start your evaluation and application development.
2 Overview
An EVM system is comprised of a CPU board with one or more application boards. The CPU board
(shown in Figure 1) can be used standalone for software debug and development. Each EVM system is
designed to enable customers to evaluate the processor performance and flexibility in the following
targeted markets:
• Automotive and infotainment applications
• Automotive and ADAS applications
The CPU board contains the DRA72x (Superset part) applications processor, a companion power solution
(TPS65917), DDR3 DRAM, several types of flash memories (QSPI, eMMC, NAND, and NOR), and a
multitude of interface ports and expansion connectors. The board provides additional support components
that provide software debugging, signal routing, and configuration controls that are not needed in a final
product. Different versions of the CPU boards will be built to support the development process that
include:
• Socketed processor for wakeup, early SW development, and quick and easy chip revision evaluation
• Soldered-down processor for high-performance use cases and evaluations
All other components on-board are soldered-down.

3.2 Power Architecture
Figure 5 shows the complete power distribution system of the EVM. The companion power management
IC (PMIC) for SoC is the TPS65917-Q1. A step-down 12-V to 3.3-V and 5-V converter is available to
provide a 3.3-V and 5-V DC input to the PMIC, as well as 3.3-V and 5-V power rails at the board level.
Refer to the PMIC data sheet for the power on/off sequence.
Figure 5. Power Distribution Block Diagram
An external power is required to power the EVM, but is not included as part of the EVM kit. The external
power supply requirements are:
• Power Jack: 2.5-mm ID, 5.5-mm OD
• Nom voltage: 12 VDC
• Max Current: 5000 mA
• Efficiency Level V
