Application Kit Information

3.1

Available Boards

The following boards are available:

– Application Kit TC397 V2.0 with VEXT=5V

– Application Kit TC397 V2.0 with VEXT=3,3V

– Application Kit TC387 V2.0 with VEXT=5V

– Application Kit TC387 V2.0 with VEXT=3,3V

If the TLF35584 is stamped with VS1 then the board has VEXT=5V.

If the TLF35584 is stamped with VS2 then the board has VEXT=3,3V.

The used VEXT voltage can also be detected by the supply measurement of the AURIX™ device itself and os

measureable on pin 2 of X102 and X103.

Note:

Only on Application Kit TC397 V2.0 with VEXT=3,3V is the SD card connected to the TC397 via SDMMC

module and P10.2/3 is used for CAN. All other boards are using QSPI for SD card access and P20.7/8 for

CAN.

Power Supply

All needed voltages are generated via Infineon’s Multi Voltage Safety Micro Processor Supply TLF35584QV and via

the microcontroller itself (+1,25V).

The supply device is available as two different devices:

TLF35584QVVS1 -> +5V standby voltage, +5V TriCore supply (V_UC)

TLF35584QVVS2 -> +3,3V standby voltage, +3,3V TriCore supply (V_UC)

Dependent of the assembled device the board works with 5V or 3,3V IO.

The TLF35584QV provide the following voltages:

+3,3V or +5V for standby (connected to VEVRSB)

+3,3V or +5V for TriCore (connected to VEXT)

+5V communcation supply (used by CAN transceiver and acoustic beeper)

+5V voltage reference (connected to VDDM and VAREFx)

+3,3V via LDO directly from pre regulator (connected to VDDP3 and VFLEX and used by Ethernet PHY, display and

SD card)

Applying a stable supply voltage causes the power on reset after a short period. The LED (V_UC) indicate the

status of the cpu voltage.

A manual power on reset is executed by pressing the reset button.

The Board has to be connected to a +3,5V to +40V DC power supply.

The board can be powered directly by USB or by the power connector. In case that the voltage on the power

connector is higher than the 5V from the USB then the board is powered by power connector.

3.2.1

Power via supply connector (X101)

The Board has to be connected to a +5,5V to +40V DC power supply.

A supply with 6V and 800mA is sufficient. The pinout for the supply connector is shown in Figure 6-2. There can be

used any standard power pack with a connector where the positive line is surrounded by the ground line.
