KIT_XMC71_EVK_LITE_V1 XMC7100 Lite Evaluation Board guide
Introduction
1Introduction
The XMC7100 Evaluation Board enables you to evaluate and develop your applications using the XMC7100D
microcontroller(hereafter called “XMC7100D”).
XMC7100D is designed for industrial applications. XMC7100D is a true programmable embedded system-on-
chip, integrating up to two 250 MHz Arm®Cortex®-M7 as the primary application processors, 100 MHz Arm®
Cortex®-M0+ that supports low-power operations, up to 4 MB flash and 768 kB SRAM, Ethernet, Controller
Area Network Flexible Data-Rate (CAN FD), programmable analog and digital peripherals that allow faster
time-to-market.
The evaluation board has two Infineon’s shield2Go standard headers (S2GO) and a mikroBus header for
interfacing sensors, and headers compatible with Arduino for interfacing Arduino shields. In addition, the
board features an onboard programmer/debugger(KitProg3), a 512 Mbit QSPI NOR flash, CAN FD transceiver,
standard 10/100 Base Tx Ethernet PHY transceiver with RJ45 connector interface, a micro-B connector for USB
device interface, two user LEDs, one potentiometer, and two push buttons. The board supports operating
voltages from 3.3 V to 5.0 V for XMC7100D.
ModusToolbox™ software is used to develop and debug the XMC7100D projects. ModusToolbox™ is a set of
tools that enable you to integrate these devices into your existing development methodology.
For more details on XMC7100D, see the AN234334 - Getting started with XMC7000 MCU on ModusToolbox™
software application note, which aids in creating a customized design using the Eclipse IDE for ModusToolbox™.
1.1 Getting started
The guide has the following sections:
•The Kit details chapter provides the kit package and board details.
•The Kit operation chapter describes the major features of the XMC7100 Evaluation Board and their
functionalities such as programming, debugging, the USB-UART and USB-I2C bridges.
•The Hardware chapter provides a detailed hardware description, kit schematics, and the bill of materials
(BOM).
•Application development using XMC7100 Evaluation Board is supported in ModusToolbox™.
ModusToolbox™ is a free development eco-system that includes the Eclipse IDE for ModusToolbox™ and the
XMC7100 SDK with XMC7100D. ModusToolbox™enables and configures device resource and middleware
libraries; writes C/assembly source code; and programs and debugs the device. The software can be
downloaded from the ModusToolbox™ home page. For more details, see the ModusToolbox™ tools package
installation guide.
•There are wide range of code examples to evaluate the XMC7100 board. These examples help to familiarize
with XMC7100D, and help to create a customized design. These examples can be accessed through
ModusToolbox™ Project Creator tool. To access the code examples, visit Infineon’s Code Example page.
1.2 Additional learning resources
Infineon provides a wealth of data on the 32-bit XMC™ Industrial Microcontroller Arm® Cortex®-M webpage to
select the right XMC™ MCU for the design and to quickly and effectively integrate the device into the design.

The XMC7100 Evaluation Board has the following peripherals.
Table 4 Peripheral details
Sl. No.
Peripheral
Description
1.
External power supply VIN
connector (J6)
External power supply from DC Jack. A DC adapter with
7 V –24 V, 2.5 A can be used as a source of power to the
kit. Not loaded by default.
2.
Power LED (LED4)
Power supply ON/OFF LED status indicator.
3.
KitProg3 USB connector (J5)
Connect to a PC to use the KitProg3 onboard programmer
and debugger and to provide power to the board.
4.
KitProg3 status LED (LED3)
Indicates the status of KitProg3. For details, see the
KitProg3 user guide.
5.
512 Mbit serial NOR flash memory
(S25HL512T - U9)
Connected to the serial memory interface (SMIF) of the
XMC7100D. The NOR flash device can be used for both
data and code memory with execute-in-place (XIP)
support and encryption.
6.
KitProg3 programming mode
selection button (SW3)
Use this button to switch between various modes of
operation of KitProg3. Note that this board supports only
CMSIS-DAP BULK mode. For more details, see the
KitProg3 user guide. This button function is reserved for
future use.
8.
XMC7100D VTARG current
measurement jumper (J12)
Connect an ammeter to this jumper to measure the
current consumed by the XMC_VDD power domain of the
MCU.
9.
XMC7100D VDDIO1 current
measurement jumper (J24)
J24 connects MCU VDDIO1 to XMC_VDD which is outcome
from J8 (VCC_3V3 or VDD_5V0) power supply selection.
Not loaded by default.
10
XMC7100D VDDIO2 current
measurement jumper (J25)
J25 connects MCU VDDIO2 to XMC_VDD which is outcome
from J8 (VCC_3V3 or VDD_5V0) power supply selection.
Not loaded by default.
11.
System power (VTARG) selection
jumper (J8)
J8 is a three-pin voltage selection header to select
between VCC_3V3 or VDD_5V0 voltages.
12.
XMC7100D 20-pin debug and trace
header (J11)
Connect to an Embedded Trace Macrocell (ETM)-
compatible programmer and debugger. This is not loaded
by default.
13.
XMC7100D 10-pin SWD/JTAG
program and debug header (J10)
This 10-pin header allows you to program and debug the
XMC7100D using an external programmer, such as
MiniProg4.
14.
XMC7100D reset button (SW1)
Resets XMC7100D. It connects the XMC7100D reset (XRES)
pin to ground.
15.
Potentiometer (R77)
10 kΩ potentiometer connected to a XMC7100D pin P6[0].
This pin has shared connection to A0 of Arduino-
compatible analog header J2 to simulate sensor output
to XMC7100D.

Kit operation
Sl. No.
Peripheral
Description
16.
Potentiometer connection jumper
(J13)
Connects the XMC7100D VDDA supply to the
potentiometer.
17.
XMC7100D extended I/O headers
(J21, J23)
These headers provide connectivity to XMC7100D GPIOs
that are not connected to the headers compatible with
Arduino. Few of these pins are multiplexed with onboard
peripherals and are not connected to the XMC7100D by
default. These connectors are not populated by default.
18.
Power header compatible with
Arduino Uno R3 (J1)
Powers the shields compatible with Arduino. It also has a
provision to power the kit though the VIN input.
19.
Analog-IN header compatible with
Arduino Uno R3 (J2)
Bring out pins from XMC7100D to interface with the
Arduino-compatible shields. Some of these pins are
multiplexed with onboard peripherals and are not
connected to XMC7100D by default. For detailed
information on how to rework the kit to access these pins,
see Table 3.
20.
XMC7100D user buttons (SW2, SW4)
Provide an input to XMC7100D. Note that by default the
button connects the XMC7100D pin to ground when
pressed, so you need to configure the XMC7100D pin as a
digital input with resistive pull-up for detecting the
button press. The SW4 button also provides a wakeup
source from hibernate mode of the device.
21.
XMC7100D user LEDs (LED1 and
LED2)
The user LEDs can operate at the entire operating voltage
range of XMC7100D. The LEDs are active LOW; therefore,
pins must be driven to ground to turn ON the LEDs.
22.
Shield2Go- S2GO2 (J16 & J18)
Infineon’s shield2go-compatible header to support
sensor functionality working with I2C, UART or SPI
interface.
23.
Shield2Go- S2GO1 (J20 & J22)
Infineon’s shield2go compatible header to support sensor
functionality working with I2C, UART or SPI interface.
24.
XMC7100D Microcontroller
(XMC7100D-F176K4160AA –U1)
XMC™ MCU device used on the kit.
25.
Mikro-Bus compatible header (J19
& J17)
MIKROE’s mikroBUS-compatible header to support
sensor functionality working with I2C, UART or SPI
interface.
26.
RJ45 Ethernet connector (U16)
RJ45 ethernet connector port to connect kit to the
Ethernet network. Not loaded by default.
27.
Ethernet physical layer (PHY)
transceiver (U12)
Ethernet PHY. Not loaded by default.
28.
