2 Hardware Description
The following sections give a detailed description of the hardware and how it can be used.
Figure 2 CPU Board XMC4200 Actuator(CPU_42A-V1)
2.1 Power Supply
The CPU_42A-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_42A-V1 board is used to drive other satellite cards e.g.
MOT_GPDLV-V2 and the total system current required exceeds 500 mA, then the CPU_42A-V1 board needs to
be powered by the satellite cards. These satellite cards support external power supply.
The typical current drawn by the CPU board without any satellite cards connected is about 170 mA (@5 V).
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.

XMC4200.

JP300
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.
2.2 Encoder Jumper
The jumper JP200 “ENENC#” on the CPU_42A-V1 board is used to enabled/disable an external unit connected
to the ACT satellite connector, e.g.an encoder line receiver on the Motor Drive Card MOT_GPLV-V2.
The signal on the encoder jumper is not connected to the XMC4200. It’s connected to pin 30 of the ACT satellite
connector only. If the jumper JP200 is shorted, a ground level is driven at pin 30 of the ACT satellite connector.
If the jumper is open the line is floating. In this case a pull-up resistor on the ACT satellite card must ensure a
high level.

2.3 CAN
The CPU_42A-V1 board provides a CAN interface via a Sub-D DE-9 connector (X200). Infineon’s high speed
CAN transceiver IFX1050GVIO for industrial application supports 3.3V I/O logic and is suitable for 12V and 24V
bus systems with an excellent EMC performance. The CAN bus is terminated on-board with 120 Ohm.

The CAN signals CAN_TXD and CAN_RXD are routed to XMC4200 port pins P1.5 and P1.4 respectively via
the switches U301 and U303.These switches will disconnect the CAN transceiver from the port pins P1.5 and
P1.4 in case a UART function is required. On these pins of the XMC4200 the UART function is overlaid with the
CAN function. The UART function can be used for external communication via a USB virtual COM port, which is
supported by the on-board debugger.

2.4 Reset
A reset signal connected to the low-active PORST# pin of XMC4200 (U300) can be issued by
an on-board Reset Button (SW400, RESET)
an on-board debugger (U500)
an external debugger connected to either of the Cortex Debug connector X400 or X401
The RESET signal is routed to all satellite connectors. The reset circuit includes a red LED (V407) to indicate
the reset status: The Reset LED (V407) will be “ON” during active reset state and will be “OFF” if reset is not
active.
Be aware that PORST# is a bidirectional reset pin of the XMC4000 family which can also be pulled low by the
XMC4000 device itself.

2.5 Clock Generation
An external 12 MHz crystal provides the clock signal to the XMC4200 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.
Figure 9 Clock Generation
2.6 Boot Option
During power-on-reset the XMC4200 latches the dip switch SW300 settings via the TCK and the TMS pin.
Based on the values latched different boot options are possible.

2.7 Debug Interface
The CPU_42A-V1 board supports debugging via 3 different channels:
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 debug is
not supported by default because the GPIO P0.7, where the required TDI function is mapped to also, 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 P0.7. For the same reason also do not use the on-board debugger in JTAG debug
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).

2.7.1 On-board Debugger
The on-board debugger [1] supports
Serial Wire Debug
Serial Wire Viewer [2]
Full Duplex UART communication via a USB Virtual COM
[1] Attention: Newer firmware versions of the on-board debugger require the latest J-Link driver (V4.62 or
higher) and a Serial Port Driver (CDC driver) installed on your computer. Please check “Install J-Link Serial
Port Driver” when installing the latest J-Link driver (see Figure 11)
Figure 11 Installation of Serial Port Driver
[2] If Serial Wire Viewer is used, the User LED cannot freely be programmed and starts flickering, because the
Serial Wire Viewer function is overlaid with the GPIO function connected to the User LED.
The on-board debugger can be accessed through the Debug USB connector shown in Figure 12. The Debug
LED V502 shows the status during debugging.
Figure 12 On-board Debugger
When using an external debugger connected to the 10pin/20pin Cortex Debug Connector, the on-board
debugger is switched off.
When using the USB virtual COM port function of the on-board debugger the on-board CAN interface is
disabled through the switches U301 and U303.

2.7.3 Cortex Debug+ ETM Connector (20-pin)
The CPU_42A-V1 board supports Serial Wire Debug operation, Serial Wire viewer operation (via SWO
connection when Serial Wire Debug mode is used) through the 20-pin Cortex Debug+ ETM Connector. The
board does not support the Instruction Trace operation.
JTAG Debug 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 port pin P0.7
is used by the Actuator boards connected to the ACT satellite connector.
