CPU Board XMC4500 SDRAM

Overview

Board User's Manual 7 Revision 1.0, 2013-02-20

Introduction

This document describes the features and hardware details of the CPU board “CPU Board XMC4500 SDRAM”

(CPU_45B-V1) designed to work with Infineon’s XMC4500 Microcontroller. This board is part of Infineon’s

Hexagon Application Kits. Please visit www.infineon.com/xmc-dev for more information about the Hexagon

Application Kit family.

1 Overview

The CPU board CPU_45B-V1 houses the XMC4500 Microcontroller and three satellite connectors (HMI, COM,

ACT) for application expansion. The board along with satellite cards (e.g. HMI_OLED-V1, COM_ETH-V1,

AUT_ISO-V1 boards) demonstrates the capabilities of XMC4500.

The main use case of this board is to demonstrate the external bus unit (EBU) of the XMC4500 device including

the tool chain. For this purpose a 64 Mbit SDRAM is connected to the XMC4500 and for external bus extension

an asynchronous 16-bit wide bus interface is available at the COM satellite connector.

Attention: This board (CPU_45B) has not been designed to work with the “General Purpose Motor Drive

Card” (MOT_GPDLV). For this purpose please use the CPU boards CPU_45A, CPU_44A or

CPU_42A.

The focus is safe operation under evaluation conditions. The board is neither cost nor size optimized and does

not serve as a reference design.

Two User Buttons connected to P5.10 and P0.10

7 LED’s

3 Power indicating LED’s

2 User LEDs (P5.2 and P1.1)

1 RESET LED

1 Debug LED

Potentiometer, connected to analog input P14.1

Power supply

−Via Debug USB connector

−Via Micro-USB connector in USB device mode

−Via satellite connector pins (COM/ACT satellites cards can supply power to CPU board)

−RTC backup battery

2 Hardware Description

The following sections give a detailed description of the hardware and how it can be used.

Figure 2 CPU Board XMC4500 SDRAM (CPU_45B-V1)

2.1 Power Supply

The CPU_45B-V1 board can be powered via either of the USB plugs (5 V); however, there is a current limit that

can be drawn from the host PC through USB. If the CPU_45B-V1 board is used to drive other satellite cards

(e.g. AUT_ISO-V1 or MOT_GPDLV-V2) and the total current required exceeds 500 mA, then the board needs to

be powered by a satellite card, which supports external power supply like e.g. AUT_ISO-V1, MOT_GPDLV-V2,

COM_ETH-V1.

The typical current drawn by the CPU board without any satellite cards connected is about 220 mA (@5V).

For powering the board through an USB interface, connect the USB cable provided with the kit to either of the

Micro-USB connector on board as shown in Figure 3.
