Board User's Manual 10 Revision 1.0, 2014-01-10
2.1 Power Supply
The CPU_45A-V3 board can be powered via the USB plug (5 V); however, there is a current limit that can be
drawn from the host PC through USB. If the CPU_45A-V3 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 either an external power supply connected to USB or by a satellite card, which supports external
power supply like e.g. AUT_ISO-V1, MOT_GPDLV-V2, COM_ETH-V1.
For powering the board through USB interface, connect the USB cable provided with the kit to the Micro-USB
connector on board.

PowerScale
A Hitex PowerScale probe can be connected for current sensing the
VDD3.3 (CPU power source). Default: pos. 1-2 (closed)
Note: On the PCB there is a shorting trace between pin 1-2. This trace has
to be cut first, before using PowerScale. Pin 3 is GND.
The maximum current drawn by the CPU board without any satellite cards connected is about 150 mA.

Board User's Manual 12 Revision 1.0, 2014-01-10
2.2 Reset
The reset pin (PORST#) of the XMC45000 is a bi-directional pin. An internal pull-up resistor will keep the
PORST# pin high during normal operation. A low level at this pin will force a hardware reset. In case of an
internal reset the PORST# pin will drive a low signal. An internal circuit of the XMC4500 ensures a save Power-
on-Reset. XMC4500 does not require any additional external components to generate a reset signal during
power-up. An on-board reset button (SW400, RESET) supports a hardware reset of the CPU during operation.
The reset signal is also routed to all satellite connectors. The reset state is indicated by a red LED (V407). The
LED will be “ON” during reset state and will be “OFF” during normal operation conditions.

2.3 Clock Generation
An external 12 MHz crystal provides the clock signal to the XMC4500 microcontroller. The drive strength of the
oscillator is set to maximum by software, in order to ensure a safe start-up of the oscillator even under worst
case conditions. A serial 510 Ohm resistor will attenuate the oscillations during operations.
For the RTC clock a separate external 32.768 kHz crystal is used on board.

2.4 Boot Option
During power-on-reset the XMC4500 latches the dip switch SW300 settings via the TCK and the TMS pin.
Based on the values latched different boot options are possible.

2.5 Debug Interface
The CPU_45A-V3 board supports JTAG debug via 3 different connectors.
On-board Debugger
Cortex Debug Connector (10-pin)
Cortex Debug+ETM Connector (20-pin)
The Hexagon Application Boards are designed to use “Serial Wire Debug”as debug interface. JTAG is not
supported by default because the GPIO P0.7 (TDI), where the required TDI function is mapped to, is used by
various Actuator boards connected to the ACT satellite connector.
Note: It is strongly recommended not to use JTAG debug mode, especially if satellites boards are
connected, which uses the GPIO 0.7. For the same reason also do not use the on-board debugger in
JTAG mode.
If you want to use the JTAG debug mode through the cortex debug connectors (X400, X401) anyway, enable
the JTAG interface of the XMC device by assembling the pull-up resistor R427 (4k7 Ohm) and the resistor R410
(0 - 33 Ohm).
2.5.1 On-board USB Debugger
The on-board debugger supports
Serial Wire Debug
Serial Wire Viewer
Full Duplex UART communication via a USB Virtual COM
The on-board debugger can be accessed through the Debug USB connector shown in Figure 10. The Debug
LED V502 shows the status during debugging.

When using an external debugger connected to the 10-pin/20-pin Cortex Debug Connector, the on-board
debugger is switched off.
When using the USB virtual COM port function of the on-board debugger the UART interface to the COM
satellite is disabled through the switches U301 and U303.

2.5.2 Cortex Debug Connector (10-pin)
The CPU_45A-V3 board supports Serial Wire debug operation and Serial Wire viewer operation (via the SWO
signal when Serial Wire debug mode is used) through the 10-pin Cortex Debug Connector.
When using an external debugger connected to the 10-pin Cortex Debug Connector, the on-board debugger is
switched off.

2.5.3 Cortex Debug+ETM Connector (20-pin)
The CPU_45A-V3 board supports Serial Wire debug operation, Serial Wire viewer operation (via SWO
connection when Serial Wire debug mode is used) and Instruction Trace operation through the 20-pin Cortex
Debug+ETM Connector.
JTAG operation additionally would require the TDI (P0.7) signal. By default the TDI signal is disconnected from
the Cortex Debug Connectors by a not assembled resistor R410, because the pin P0.7 is used by the Actuator
boards connected to the ACT satellite connector.

2.7 USB
The XMC4500 supports USB interface in host only mode, device only mode or as an OTG Dual Role Device
(DRD). In USB device mode, power is expected through VBUS (pin 1) from an external host (e.g. PC). When
the current is more than 500 mA power from an external source through satellite cards shall be used.
Note: Some PCs, notebooks or hubs have a weak USB supply which is not sufficient for proper supply. In this
case use an external 5 Volt power supply or a powered USB hub.
Figure 17 USB Connector Schematic
Port P0.9 of XMC4500 is connected to the USB ID pin (pin 4). An OTG device will detect whether a USB 3.0
Micro-A or Micro-B plug is inserted by checking the ID pin. When the ID = FALSE, Micro-A connector is plugged
and when ID = TRUE a Micro-B connector is plugged in. When ID is true the XMC4500 acts as USB host else
as USB device.

CPU_45A-V3
CPU Board XMC4500 General Purpose
Hardware Description
Board User's Manual 20 Revision 1.0, 2014-01-10
In the host only mode and OTG mode the CPU_45A-V3 board is capable of supplying power to the connected
device (e.g. USB mouse). The board has a power-switch which is controlled by the XMC4500. Port P3.2 (active
high) is used for this purpose. In the Host/OTG mode a low active FAULT signal indicates to XMC4500 via
HIB_IO_0 signal, if more than 500 mA current is drawn by the external device. HIB_IO_0 signal is used as
general purpose input pin for this implementation.
Diode V400 will allow powering the board through USB in all USB modes via e.g. a PC.
