Safety precautions
Note: Please note the following warnings regarding the hazards associated with development systems.
Table 1 Safety precautions
Caution: The heat sink and device surfaces of the evaluation or reference board
may become hot during testing. Hence, necessary precautions are required while
handling the board. Failure to comply may cause injury.
Caution: Only personnel familiar with the drive, power electronics and associated
machinery should plan, install, commission and subsequently service the system.
Failure to comply may result in personal injury and/or equipment damage.
Caution: The evaluation or reference board contains parts and assemblies
sensitive to electrostatic discharge (ESD). Electrostatic control precautions are
required when installing, testing, servicing or repairing the assembly. Component
damage may result if ESD control procedures are not followed. If you are
not familiar with electrostatic control procedures, refer to the applicable ESD
protection handbooks and guidelines.
Caution: A drive that is incorrectly applied or installed can lead to component
damage or reduction in product lifetime. Wiring or application errors such as
under-sizing the motor, supplying an incorrect or inadequate DC supply, or
excessive ambient temperatures may result in system malfunction.
Caution: The evaluation or reference board is shipped with packing materials
that need to be removed prior to installation. Failure to remove all packing
materials that are unnecessary for system installation may result in overheating or
abnormal operating conditions.

1 Overview
1.1 Description
The uIO-Stick v2 is an interface device for controlling EvalBoards of the MOTIX™MCU devices during run time
through PC.
It oers a USB connection to the PC, and several dierent functionalities, for example SPI, CAN, and GPIOs.
The uIO-Stick v2 registers as an HID on the PC, so no driver installation is needed.
Figure 1 uIO-Stick v2
1.2 Block diagram
The uIO-Stick v2 contains an XMC4200 microcontroller which provides the necessary hardware interface and
handles the protocols. LIN and CAN are implemented as true physical layers (using transceivers), while the
digital lines (SPI, GPIOs) provide a 3.3 V or 5 V digital level (configurable by SW). In addition, a boost converter is
implemented to generate a 12 V supply for the target device and the integrated LIN transceiver.

2 Hardware connection
The uIO-Stick v2 can be connected to the user PC via USB. For this purpose, it has a micro-USB socket. A
micro-USB cable is not included in the packaging.
For connection to an embedded device, the uIO-Stick oers several dierent interfaces available on a 16-pin
header. The connector cable, included in the packaging, fits to the 16-pin connector on the EvalBoards of the
MOTIX™MCU devices. The following figure and table describe the pinout of the 16-pin connector.

Additional remarks:
• Pin 2 - GND: the common ground connection to the target system
• Pin 5 - LIN: can be directly connected to a LIN network; is the LIN bus connection to the LIN transceiver
implemented in the uIO-Stick v2
• Pin 6 - VS: can either be driven from the implemented boost converter on the uIO-Stick v2 (+12 V) or can
be overridden by an external supply, for example the supply of the target device. This pin is also used to
internally drive the LIN transceiver available on the uIO-Stick v2
• Pin 7 - Target Reset: intended to drive the reset input of the target device
