Figure 2 PCB of the XMC4300 Relax EtherCAT®kits
2.1 Power supply
The XMC4300 Relax EtherCAT®Kit must be supplied by an external 5 volt DC power supply connected to any
of the micro USB plugs (X100, X101). Out of the box with the pre-programmed EtherCAT®slave application and
the on-board debug probe in operation, the XMC4300 Relax EtherCAT®Kit typically draws about 440 mA in an
EtherCAT®environment. This current can be delivered via the USB plug of a PC, which is specified to deliver up
to 500 mA. The green Power LED (VDD3.3) indicates the presence of the generated 3.3 V supply voltage.
On-board reverse current protection diodes will ensure safe operation when power is provided through both
USB plugs at the same time. These protection diodes allows to use the on-board debug probe connected with a
PC/Notebook via X101 and a second host PC/Laptop connected with the XMC4300 Relax EtherCAT®Kit via X100.
If the board is powered via a USB plug, it is not recommended to apply an additional 5 Volt power supply to one
of the 5 Volt power pins (VDD5, 5 V) on the Arduino headers or mikroBUS™socket, because there is no protection
against reverse current into the external power supply. These power pins can be used to power an external
circuit, but care must be taken not to draw more current than USB can deliver. A PC acting as a USB host can
typically deliver up to 500 mA current. If higher currents are required and in order to avoid damage to the USB

host, the use of an external USB power supply which is able to deliver higher currents than 500 mA is strongly
recommended.
Aer power-up the green DEBUG LED starts blinking. When there is a connection to a PC via the Debug USB
plug X101 and the USB Debug Device drivers are installed on this PC, the DEBUG LED will turn from blinking to
constant illumination.

Figure 4 Mapping of Arduino™functions to XMC™pin functions
The XMC4300 Relax EtherCAT®Kit features a bi-directional voltage level shier and therefore supports 5 V
Arduino shields as well as 3.3 V Arduino shields. Jumper JP300 (IOREF) determines whether the Arduino shield
is driven with 5 V or 3.3 V.
The analog input signals (ADC0-5) are limited to 3.3 V input voltage. A serial 100 Ohm resistor protects the
analog input pin against overcurrent.
Primarily, ADC0 to ADC3 should be used as analog inputs, because there is no additional circuit connected
to these pins, whereas ADC4 and ADC5 have additional circuitry and require an input signal with low input
impedance (<500 Ohm).
Note: Parallel operation of I2C and ADC4/ADC5 is not possible, because they share the same Arduino pins.
2.3 mikroBUS™socket
The mapping of GPIOs and XMC™pin functions to mikroBUS™functions can be found in Table 5. The mikroBUS™
connector supports
• SPI interface with one chip select (SPI_xxx)
• I2C interface (I2C_xxx)
• UART interface (UART_xxx)
• PWM signal output (PWM)
• ADC input (ADC)

Attention:Jumper JP300 (IOREF) must be set to 3.3 V (VDD3.3) when using click™boards. 5 V click™boards
cannot be used with the XMC4300 Relax EtherCAT®Kit.
Note: The mikroBUS™UART and debugger’s UART shares the same USIC channel (U1C0) of the XMC4300
device, but do not share the same pins. Parallel operation by time multiplexing is possible.

2.5 Debugging and UART-to-USB communication
The XMC4300 Relax EtherCAT®Kit supports debugging via 2 dierent channels:
• On-board debug probe
• 10-pin Cortex®Debug connector (not assembled)
2.5.1 On-board debug probe
The on-board debug probe supports Serial Wire Debug (SWD) and UART communication. Both require the
installation of Segger’s J-Link Driver which is part of the DAVE™installation. DAVE™is a highly eicient
development platform for the XMC®microcontroller families to simplify and shorten soware development.
It can be downloaded at http://www.infineon.com/dave. The latest Segger J-Link Driver can be downloaded
at http://www.segger.com/jlink-soware.html. Table 4 shows the pin assignment of the XMC4300 used for
debugging and UART communication.

2.6 Reset
The reset pin (PORST#) of the XMC4300 is a bi-directional pin in open drain mode. An internal pull-up resistor
keeps the PORST# pin high during normal operation. A low level at this pin will force a hardware reset. In case
of a MCU internal reset the PORST# pin will drive a low signal.
A reset signal can be issued by
• the on-board Reset Button (SW102, “RESET”)
• the on-board debug probe (IC101.46)
• the external debugger connected to the 10-pin Cortex®debug probe connector (X102
• the Arduino Power Header (RESET)
• the mikroBUS™socket (RST)
An XMC™internal circuit always ensures a safe Power-on-Reset. The XMC™does not require any additional
external components to generate a reset signal during power-up.
2.7 CAN transceiver
The XMC4300 Relax EtherCAT®Kit provides a CAN interface via a D-Sub DE-9 connector. Infineon’s high speed
CAN transceiver {IFX1051LE) for industrial applications supports 3.3V I/O logic and is suitable for 12 V and 24 V
bus systems with an excellent EMC performance. The CAN bus (signals CANH, CANL) are terminated by a 120
Ohm resistor.

2.8 Phy-2-Phy EtherCAT®connection
For backplane/mid-plane oriented EtherCAT®applications, communication can be implemented without using
isolation transformers. Instead, low-cost ceramic capacitors can be used. The PCB layout of the XMC4300 Relax
EtherCAT®Kit has been prepared for EtherCAT®operation through direct Phy-2-Phy connection.
For this purpose two XMC4300 Relax EtherCAT®kits are required and some modifications must be made to the
kits (see Figure 6). All components required for this modification can be found attached to the kit.
• Remove four 0 Ohm resistors from each XMC4300 Relax EtherCAT®Kit
• Solder two 0 Ohm resistors onto each XMC4300 Relax EtherCAT®Kit
• Solder the connectors onto the XMC4300 Relax EtherCAT®Kits
Note: Aer this modification EtherCAT®communication through the RJ45 is disabled.
