1. Evaluation Board Overview
There are 4 banana sockets, 5 LEDs, three buttons, one connector for the uIO and a set of headers for
jumper configuration in the evaluation board. The functionalites will be explained in the next chapters. The
distribution of these elements in the board can be observed in the following figure:
2. Banana Sockets
The SBC is usually supplied through the VSUP input and GND banana sockets.
The VCC1 output (5 V or 3.3 V, depending on the SBC’s version) and VCC2 (5 V) banana sockets provide
the regulated voltages from the SBC. The voltages VCC1 and VCC2 are used to supply the VCC1 and VCC2
supply indication LEDs which can be disconnected via the jumpers directly next to the banana outputs of
VCC1 and VCC2.

3. Buttons
In the upper right corner there are three buttons.
Test Button for enabling test mode (press during SBC Init-Mode when sending arbitrary SPI command)
Reset Force this button is connected in parallel to RO output of SBC and will connect RO line to GND
when pressing to force a low signal on RO
Wake this buttons will do a voltage transition on the wake input of SBC to trigger an external wake
4. LEDs
In the upper left corner are 3 LEDs to indicate the state of the Fail-Outputs. The LEDs can be disconnected
via the jumper directly under the LEDs. There are also two indication LEDs for the status of VCC1 and VCC2
(see behind the banana sockets for VCC1 and VCC2) which can be also disconnected via the jumpers directly
next to the banana connectors of VCC1 and VCC2
5. Connectors
5.1. uIO Connector
The uIO Connector is used for connecting to the uIO stick, but can be also used to access the uC
interfacing pins. The pin distribution of the connector is shown in the following figure:

5.2. Digital IO Connectors
This connector can be used to access the RXD and TXD pins of the appropriate CAN and LIN transceivers
5.3. Transceiver Connectors
Those connectors can be used to connect to the transceiver outputs LIN1-LIN4 and to CAN.

6. Jumper Configurations
6.1. FO connect / disconnect jumpers
The approbriate FOx LEDs can be connected / disconnected from / to the FOx pins to indicate its status. Also
the jumpers can be used to connect an external fail circuitry.

6.2. VCC2 / VLIN jumpers
Those jumpers are located directly next to the jumpers of the fail outputs LEDs (see overview picture).
Depending on the configuration you can select the input supply of VCC2 regulator and the VLIN supply to
either VSUP (which is directly the banana socket input) or to VS (which is the ouput of boost-converter).

6.3. VCAN jumper
This jumper can be used to select the supply of the VCAN input. It can be connected either to VCC1 or
VCC2. VCAN must be supplied with 5V. Therefore – in case of DCDC SBC V33 type, this jumper must be
connected to VCC2.

7 Usage of ConfigWizard
Please connect your uIO stick to the uIO interface header and supply the evaluation board with e.g. 12V.
After this, please open “Config Wizard for SBC” inside Infineon Toolbox and select “TLE9273”. In case it has
problems to connect please refer to the uIO stick user manual which can be also downloaded under
http://www.infineon.com/SBC

After this, when the user interface is opening, then the SBC should be in SBC normal mode and SPI should be
accessable. This is indicated by green status flags.
All functionalities of the SBC are live controllable then by just clicking or selecting the appropriate functions.
