3Application Kit Information
3.1Power Supply
The microcontroller needs 3 different supply voltages. This voltages are generated via
Infineon’s Multi Voltage Safety Micro Processor Supply TLF35584QV (+3,3V and +5V
volt for ADC and CAN) and via the microcontroller itself (+1,3V).
Applying a stable supply voltage causes the power on reset after a short period. The
LED' (+3V3) indicate the status of the 3,3V voltage.
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.
A manual power on reset is executed by pressing the reset button.
3.1.1Power via supply connector (X101)
The Board has to be connected to a +5,5V to +40V DC power supply.
A supply with 6V and 500mA is sufficient. The pinout for the supply connector is shown
in Figure 5-2. There can be used any standard power pack with a connector where the
positive line is surrounded by the ground line.
3.1.2Power via Micro USB (BU301)
The Board can also be powered by the Micro USB connector. The power consumption
of the board is approx. 400mA. Use an USB port which can deliver 500mA (USB 2.0) or
900mA (USB 3.0). Most USB hubs are not able to drive more than 100mA and can’t be
used.
Also it is possible to power the board with a cellular battery charger which has 5V output
and use Micro USB for connecting.
The pinout for the USB connector is shown in Figure 5-3.
3.1.3Multi Voltage Safety Micro Processor Supply TLF35584QV
The board has assembled the Safety Micro Processor Supply with the following
Features:
•High efficient multi voltage power supply chip
•Serial step up and step down pre regulator for wide input voltage range from 3.0 to
40 V with full performance and low over all power loss
•Low drop post regulator 5.0V/200mA for communication supply (named LDO_Com)
•Low drop post regulator 3.3 V/600 mA (VS2) for μC supply (named LDO_μC)
•Provides enable, sync out signal and voltage monitoring (inside device to be added
to reset function) for an optional external post regulator for core supply (not used)

•16-bit SPI
•Safe state control with two safe state signals with programmable delay
•Input voltage monitoring (over voltage switch off)
•Green Product (RoHS compliant)
•ISO26262 compliant
•AEC Qualified
The TLF35584 is connected to the CPU via QSPI2 and use QSPI2_SLSO1 (P14.2) as
chip select. Via this spi connection the power supply will be configured (Watchdog,
device states and soon).
For more information see the data sheet of TLF35584. Because the TC234 and TC224
are 3,3V devices we use the 3,3V version of the TLF35584 (VS2).
3.2Real Time Clock
The board is equipped with a RTC MCP79511 from Microchip. The device is powered
from the standby voltage of the TLF35584 and is also powered when the TLF35584 is
switched to standby mode. For backup when the TLF35584 is not powered then there is
a small battery to hold the value inside the RTC. The RTC is connected to the
microcontroller via QSPI3 and can trigger an SCU_REQ8 (P33.7) interrupt (activ high)
with the alarms. Also an alarm from the RTC will wake-up (switch on) the board if the
board is powered and the supply is switched off.
The MCP79511 contains also an unique ID in the format EUI-48. This id can be used as
mac id for ethernet if the assembled CPU support ethernet.
For more information about the RTC please see the datasheet of MCP79511.
3.3XGA Display
The board has an XGA Display with a resolution of 320x240. The display has an ILI9341
display controller. Please see the datasheet of the display controller for the register of
the controller. The display is connected to the the microcontroller via an SPI to Parallel
converter (U201).
The SPI to Parallel converter is based on a statemachine. This state machine is clocked
with the clock of SPI, here SCLK0 (P20.11). Each rising edge of P20.11 will change the
state of statemachine. When SLSO08 (P20.6) is not low then the state machine will go
always in the idle state with a valid clock edge.

3.3.1Write a display register
A single write to any register can be done by a 32 bit transfer of SPI. Make sure that the
SLSO08 is low during this 32 bit. Bit 31 must be transfered first.
Bit 31 must be 0, this will be indicate a write access.
Bit 30 must be 0, this will be indicate a single access.
Bit 29...Bit 22 is the 8 bit register number which will be written
Bit 21...Bit 6 is the 16bit value which will be written
Bit 5...Bit 0 are dummy bits which are used to execute the write.
To speedup the writing (e.g. write to ram of display controller) it is possible to make a
endless transfer. This is done by this:
first 10 bit transfer
Bit 9 must be 0, this will be indicate a write access.
Bit 8 must be 1, this will be indicate an endless transfer.
Bit 7...Bit 0 is the 8 bit register number which will be written
Now you need to transfer only 16bit values for the registers. With the first 16 bit value
there is no action on the display. With the second value transfer is a write to the register
started. This means after the last value you must make a dummy transfer to write the last
value.
The endless mode can only be leave by a rising edge of SCLK0 with SLSO08 set to high.
This can be done by a dummy transfer to any other chip select or by a transfer from the
touch controller.
3.3.2Read a display register
A single read from any register can be done by a 32 bit transfer of SPI. Make sure that
the SLSO08 is low during the complete transfer.
first transfer has 16 bit:
Bit 15 must be 1, this will be indicate a read access.
Bit 14 must be 0, this will be indicate a single access.
Bit 13...Bit 7 is the 8 bit register number which will be read
Bit 5...Bit 0 are dummy bits to setup the register number.
second transfer must have 26 bits:
Bit 25...Bit 16 are dummy bits which are needed to readout the register value
Bit 15...Bit 0 are dummy bits to transfer the readed value.
To speedup the reading (e.g. reading from ram of display controller) it is possible to make
a endless transfer. This is done by this:
first 16 bit transfer:

Bit 5...Bit 0 are dummy bits to setup the register number.
second 10 bit transfer:
Bit 9...Bit 0are dummy bits which are needed to readout the register value
Now you need to transfer only 16bit values for the registers. With the each 16 bit transfer
you get a value. With the last transfer you have dummy read which you don’t get the
result.
The endless mode can only be leave by a rising edge of SCLK0 with SLSO08 set to high.
This can be done by a dummy transfer to any other chip select or by a transfer from the
touch controller.
3.3.3Touch controller
The touch of display is connected to an Touch controller ADS7843. This controller is
connected via the QSPI0 and SLSO9 to the microcontroller. For more information about
the delivered values from the touch controller please see the datasheet of ADS7348.
3.4Micro SD card
The board has a slot to use the board with an micro SD card. The card will be used in
