Safety Instructions
●
When working with the XMC-CPU/Zulu follow the instructions below and read the manual
carefully to protect yourself from injury and the XMC-CPU/Zulu from damage.
●
The device is a built-in component. It is essential to ensure that the device is mounted in a way
that cannot lead to endangering or injury of persons or damage to objects.
●
Do not use damaged or defective cables to connect the XMC-CPU/Zulu and follow the CAN
wiring hints in chapter: "Correct Wiring of Electrically Isolated CAN Networks".
●
In case of damages to the device, which might affect safety, appropriate and immediate
measures must be taken, that exclude an endangerment of persons and domestic animals and

live parts with high voltages inside of the system into which the XMC-CPU/Zulu is to be
integrated.
→
→
All current circuits which are connected to the device have to be sufficiently
protected against hazardous voltage (SELV according to EN 60950-1) before you
start with the installation.
Ensure the absence of voltage before starting any electrical work
NOTICE
Electrostatic discharges may cause damage to electronic components.
To avoid this, perform the steps described on page 19 before you touch the XMC-
CPU/Zulu, in order to discharge the static electricity from your body
→
→
To avoid this, discharge the static electricity from your body before you touch the
XMC-CPU/Zulu.

1 Overview
Figure 1: Block circuit diagram
64-Bit XMC ARM®Host CPU
The XMC-CPU/Zulu in XMC form factor comes with a XILINX®Zynq®UltraScale+TM CG
multiprocessor system-on-chip with 1.3 GHz core frequency.
The local memory bus has a bus width of 32 bits and an overall capacity of 1 Gbyte.
64 Mbyte SPI Flash for boot loader and 32 Kbit I²C EEPROM for U‑Boot environment.
XMC-CPU/Zulu features a 16-Gbyte eMMCTM memory which is used for operating system, file
system and application software.
The XMC interface comes with quad-lane PCIe®bus and is designed according to VITATM 42.3.
Two Gigabit Ethernet interfaces are accessible via the front panel of the XMC-CPU/Zulu. This gives
an excellent base for EtherCAT®applications.
Two additional rear IO Ethernet interfaces are accessible via the XMC connector P6. The rear IO
Ethernet interfaces come without electrical isolation.
Two of the GB Ethernet interfaces (one front, one rear) are rooted through the FPGA. Therefore,
special Ethernet IP-cores can be implemented.
A serial interface, designed as terminal interface, is accessible via an USB Mini type-B connector on
the front.
The Flash memory carries the standard boot program “Das U-Boot” and enables the XMC-CPU/Zulu
to boot various operating systems from on-board Flash, network or eMMC.
Board support packages are available for Linux®and VxWorks®. The BSPs include an example
source code for the FPGA. Programming of the FPGA is done via XILINX Toolchain.
The esd EtherCAT Master Stack is available for various operating systems.

4 Hardware Configuration
The DIP-switch MODE and the 3 SMD tactile switches PROG, SRST and POR are equipped on the
bottom layer of the XMC-CPU/Zulu. See Figure 3 on page 12 for the position on the PCB.
Figure 6: Position of the switches (detail)
4.1.1Mode
The DIP-switch MODE (PS_MODE) comes with 4 Mode pins. With the DIP-switch the boot mode
can be selected. Depending on the setting of the switches the BootROM boots the system from
Quad-SPI (24b or 32b), SD or eMMC external boot devices.

5 Hardware Installation
NOTICE
Read the safety instructions at the beginning of this document carefully before you
start with the hardware installation!
WARNING
Hazardous Voltage - Risk of electric shock due to unintentional contact with uninsulated
live parts with high voltages inside of the system into which the XMC-CPU/Zulu is to be
integrated.
→
→
Disconnect all hazardous voltages (mains voltage) before opening the system.
Never carry out work while power supply voltage is switched on!
Ensure the absence of voltage before starting any electrical work.
NOTICE
Electrostatic discharges may cause damage to electronic components.
→
→
To avoid this, please discharge the static electricity from your body before you touch
the XMC-CPU/Zulu.
Furthermore, you should prevent your clothes from touching the XMC-CPU/Zulu,
because your clothes might be electrostatically charged as well.
Procedure:
1.
Switch off your system and all connected peripheral devices (monitor, printer, etc.).
2.
Discharge your body as described above.
3.
Disconnect the system from the mains.
Make sure that no risk arises from the system into which the XMC-CPU/Zulu shall be
inserted.
WARNING
Hazardous Voltage
Risk of electric shock due to unintentional contact with uninsulated live parts with
high voltages.
→
→
→
→
Disconnect all hazardous voltages (mains voltage) before opening the system.
If the system does not have a flexible mains cable, but is directly connected to
mains, disconnect the power supply via the safety fuse and make sure that the fuse
cannot switch on again unintentionally (i.e. with caution label).
Ensure the absence of voltage before starting any electrical work.
Cover or block off adjacent live parts.
4.
Open the case if necessary.
5.
For sufficient EMC shielding the XMC-CPU/Zulu shall make contact to the system's enclosure
nearly completely around its front panel. For this purpose, a conductive O-ring is contained in
the product package of the XMC-CPU/Zulu module. Mount the conductive O-ring on the front
panel of the XMC-CPU/Zulu. Additionally, or instead of it use shielding material as for example
conductive shielding gasket.
6.
Make sure that the XMC-CPU/Zulu is configured according to your needs:
- For the configuration of the hardware see chapter “Coding Switch and Reset Buttons” on
page 17.

XMC-CPU/Zulu
7.
Remove your carrier board (if already installed) and plug the XMC-CPU/Zulu carefully on the
carrier board. Pay attention that the XMC-CPU/Zulu is correctly installed on the carrier board.
NOTICE
Please note that the number of mating cycles of the XMC connectors P5 and P6 is
only 10! Do not uninstall the XMC-CPU/Zulu from the carrier board if it is not
absolutely necessary!
Fix the XMC-CPU/Zulu with the screws on the carrier board. Use the four M 2.5 x 5 mm screws
which are contained in the product package of the module.
8.
Install the carrier board in your system.
9.
Connect the Ethernet and the CON interface via the connectors in the front panel of the XMC-
CPU/Zulu.
10.
Close the system's case again (if applicable).
11.
Connect the system to mains again (mains connector or safety fuse).
12.
Switch on the system and the peripheral devices.
13.
End of hardware installation.
14.
Set the interface properties in your operating system. Refer to the documentation of the
operating system.
