2 Overview
2.1 Description
The µIO-Stick is an interface device for controlling Infineon boards/kits during run time through PC. It enables
the connection between the evaluation board and USB for SPI programming and monitoring. Besides, it plugs
into the evaluation board via a standard 16-pin connector and allows easy interface to the microcontroller via
USB for communication through UART, SPI, LIN. It also implements GPIO ports, PWM generation up to 20 kHz
and an analog measurement interface (ADC).
Figure 1 µIO-Stick Overview
The µIO-Stick provide two exclusive functions:
1. Infineon Embedded Power Fast LIN BSL Support
The Infineon Embedded Power devices provide a built-in boot strap loader (BSL), for programming the
embedded power devices over the built-in LIN transceiver or UART. The µIO-Stick acts as an interface
between the embedded power device and a PC. It handles the BSL protocols as well as the physical
layers. A PC application provides access to all BSL functions of the Embedded Power device.
Supported Embedded Power ICs:
• TLE984x family
• TLE986x family
• TLE987x family
2. Run-Time Control - Programming and Monitoring
The µIO-Stick connects the Evaluation Board with the computer. Via the ConfigWizard soware – a
powerful and intuitive Graphical User Interface (GUI) – the user gets a customized programming,
monitoring and evaluation support for various Infineon Automotive Products.
Supported Devices:
• System Basis Chip (SBC)

2.2 Key Features
The µIO-Stick provides the following features:
• Communication with the connected device via LIN, SPI and UART
• Four GPIOs
• PWM signal generation up to 20 kHz
• Measurement of analog voltages up to 20 V
• Read and keep functionality to detect reset of the connected device
• USB HID device, no additional driver installation required
• µIO-Stick can power a target device
• Connected device can also be powered by external power supply for higher current
• 3 on-board status LEDs
• Additional BSL updater GUI for BSL communication with Embedded Power devices
2.3 Block Diagram
The µIO-Stick consists of an XMC4200 micro-controller which provides the necessary hardware interface and
handles the USB and BSL protocols.
LIN and RS232 are implemented as true physical layers (using LIN and MAX transceivers), while the digital lines
(SPI, GPIOs) provide a 5V-TTL level.
In addition, a small switchable charge-pump is implemented to generate a +12 V/200 mA supply for the target
device and the integrated LIN transceiver.

3 Hardware Connection
3.1 Pin Assignment
The µIO provides two interfaces, the USB interface to be plugged into the PC, and a 16-pin header to access the
BSL interface. Figure 3 provides a view into the 16-pin header of the µIO-Stick, including the pin numbering.
Figure 3 µIO-Stick Pin View
Table 2 lists the pin usage of the 16-pin header. The gray shaded pins are not used for BSL functions and
therefore will not be considered further.

Pins 1, 3 - RS232 They are used for UART BSL communication and need to be connected to the corresponding
RS232 inputs of the target board.
Attention: The RS232 pins are no TTL pins but real RS232 levels (MAX232 driven).
Pin 5 - LIN This is the LIN bus connection to the LIN transceiver implemented in the µIO- Stick, it is suited to
drive a corresponding LIN input of the target system.
Pin 7 - Target Reset This pin is intended to drive the reset input of the target device in order to synchronize the
device state with the attempts to establish a BSL connection. The connection of this pin to the reset of the target
device is not necessarily required, as synchronization can also be achieved by:
• power cycling of the target device by Pin 6 (VS)
• keeping the target device in BSL mode by configuring an appropriate NAC value
Pin 2 - GND This is the common ground connection to the target system.
Pin 6 - VS This pin can either be driven from the implemented charge-pump of the µIO-Stick (+12 V/200 mA) or
can be overridden by an external supply, i.e. the supply of the target device. This pin is also being used to
internally drive the LIN transceiver available on the µIO-Stick. If BSL communication over the LIN interface is
intended, then the supply of Pin 6 is mandatory.

3.2 Examples
Figure 4 shows the minimum required connection from the µIO-Stick to the target device in order to establish a
BSL communication over the LIN interface. This applies to both Normal-LIN and FastLIN protocols. To be able to
establish a BSL connection, the target device either has to stay in BSL mode upon power up (fresh device), or a
power cycling (VS - Pin 6) done by the µIO-Stick would be required.
Figure 4 Normal LIN and FastLIN connection, without reset, target supplied by µIO
Figure 5 shows a connection scenario with reset. The µIO-Stick actively resets the target device in order to start
BSL communication. In this case a power cycling of the VS (Pin 6) by the µIO-Stick would not be required.
