This board must only be used for test applications
in an evaluation laboratory environment.
1.3
General Description
The MotorKit-91F267-MC supports the 32bit MB91F267(N) Flash microcontroller.
The board is supplied with a socketed 4MHz crystal as the main oscillation clock. Using the
internal PLL of the µC, internal clock rates up to 32MHz can be achieved.
Two separate RS232 transceivers are available to connect two on-chip UARTs to 9-pin DSub connectors (X1, X2). The transceivers generate the adequate RS232 levels for the
receive (RXD) and transmit (TXD) lines. The DTR line can be selected with jumpers (JP17,
JP19) to generate a system reset. The RTS signal can be shortcut to CTS using the jumpers
JP5 and JP26. The signals to and from the UART interfaces can be galvanically isolated by
optocouplers and a separate supply by a DC-DC converter to avoid interference with a host
PC.
In-circuit-programming (asynchronous) can be done via UART0 (X1) using the burn-in
bootloader of the microcontroller.
One CAN transceiver is available to integrate the board in a Controller Area Network. The
CAN interface can be opto-isolated or connected to the MCU directly independently of the
UART interfaces.
All pins of the microcontroller (except oscillator pins X1 and X0) are connected to the pin
headers J1-J4 and are directly available to the user. Furthermore, the most important signals
like voltage and current measurements are available on separate pin headers.
The on-board voltage regulators allow the user to configure the board to fit a variety of
situations. The board includes a 15V-regulator for the gate drivers, as well as a 5V-regulator
for the MCU and logic supply. The 15V regulator can be bypassed (JP20) if the source input
voltage is in the range of 10-20V. The 5V regulator can use a separate 8-15V input or use
the gate drive supply as regulator input. Also, solder jumpers (JP29 and JP63) can be set to
supply the DC bus from the logic power supply input (X6), e.g. when using a small motor
(<3A).
There are seven push button switches on the board, which can be connected to input pins of
the microcontroller. SW1 (NMI) can be connected to the NMI pin. SW2-SW5 can be
connected to various I/O pins of the MCU. Additionally, by setting JP7, all buttons can trigger
the external interrupt 7, which is normally connected only to SW2 ('wired-OR'). This allows
reading all buttons in a single ISR and saves external interrupt pins. SW6 is the system reset
button, and SW7 triggers the fault input pin (DTTI) of the MCU, which can shut down the
PWM output in case of over-current or over-voltage.
Eight user-LEDs are connected via a 1K pull-up resistor network to Port P00-P07. If these
LEDs are not required, the resistor network can be removed to disconnect the LEDs and free
the port.
The operating mode of the microcontroller (Program / Run) is selected by JP18.
The board provides current and voltage measurement circuits for the motor phases and the
DC bus which are connected to the ADC of the microcontroller. The signal conditioning
circuit fits a variety of applications. Some applications might require a faster or slower
filtering e.g. of the voltage measurement; this can be done by changing R/C values or
adding capacitors in the current measurement circuit (e.g. C70, C72, C75, C77).

2 Installation
Carefully remove the board from the shipping carton.
Check if there are any damages before power is applied to the evaluation board.
For the logic power supply a DC input voltage of 9V – 15V is recommended. The
positive voltage (+) must be connected to the shield, and ground (GND) must be
connected to the center of the connector X6!
By default, the DC bus is supplied through the screw terminal J5. Connect to an
adequate power supply for the motor in use (24V max.). Be aware that this input is not
protected against false polarity. Always connect ‘+’ to the terminal close to the upper
board edge, and GND to the one close to X6.
Further, it is strongly recommended to use a laboratory DC power supply with
adjustable current limitation with this board. Otherwise, in case of software or
hardware malfunctions or false configurations, high currents can flow and damage
the power supply and/or the board and lead to overheating by excessive power
dissipation.
After power-on, the green power-on LEDs (LD2 and LD3) should be on, depending on the
configuration of the corresponding jumpers. If the LEDs do not light, switch off the power
supply and check the jumper settings according to the desired configuration.
By default, the evaluation board is equipped with an MB91F267N Microcontroller.
The in-circuit programming allows the user to program an own application into the Flash
memory. Programming of the Flash memory is described in chapter 4.
Depending on the power supply used for the DC bus input, it might be necessary to protect
the power supply against reverse current. This can occur when shutting down the power
supply with the board attached, or when an attached motor is externally accelerated or
quickly decelerated and thereby works as a generator. This protection can be done by a
diode of sufficient current capability. Since many power supplies are vulnerable to this issue,
inserting a shottky diode is recommended.
Depending on the application, the use of an external brake chopper circuit might be
necessary. Typical applications are high-speed or varying load applications, such as
centrifuges or elevators, in which the motor can be also moved by the load. Especially if the
motor can be externally accelerated beyond the nominal speed, high voltages can occur
which may damage the hardware.
The board is shipped with power transistors in a D2PAK package. For additional flexibility,
there are also soldering options for power MOSFETS in TO-220 packages, which can be
mounted on external heat sinks. In this case, probably also the current measurement shunts
should be replaced with a smaller value or bypassed to reduce heat.

Power Supply (JP: 13, 14, 28, 29, 31, 32, 63)
The evaluation board supports a variety of different input voltages. The regulator input for
MCU and logic supply can be provided either by a separate power input (X6), by the gate
driver supply voltage or it can be connected directly to the DC bus. The supply voltage for
the gate drive circuits must be in the range of 10-20V and can be derived either from the DC
bus or X6. A 15V voltage regulator can be inserted in case the used input voltage is higher
than 20V.
The UART and CAN interfaces can be optically isolated. Therefore, a DC-DC converter and
optocouplers are supplied on the board. They are placed in sockets, and can be bypassed
when not present.
JP13 Vcc_COM = VCC5
This jumper connects the transceiver supplies with the MCU supply when no DC-DC
converter is used (no galvanic decoupling)
JP14 GND_COM = GND
This jumper connects the transceiver ground with the MCU ground when no DC-DC
converter is used (no galvanic decoupling)
JP28 VCC15V Source
This jumper selects whether the gate driver supply voltage is fed from the 15V
voltage regulator or directly from the DC bus voltage
JP29 P_connect
This jumper can be used to connect the DC bus and gate driver supply to the supply
input X6. This can be useful when a small motor is used and the entire system is
powered by X6, or when JP63 is open, it is also possible to supply the gate driver
from X6 and only the DC bus by J5 (default).
JP31 Power
This jumper can be used to switch the logic supply on and off.

MotorKit-91F267-MC User Guide
JP32 VCC5V source
This jumper selects the source for the 5V voltage regulator input. This can either be
the gate driver voltage, or X6/JP29.
JP63 Bus power connect
This jumper connects the DC bus voltage input J5 with the logic and gate driver
supply. To vary the DC bus voltage from 0-30V independently of the other supply
voltages, open JP63 and supply 10-15V at X6. JP28 and JP32 should then be in 1-2
position.

WARNING: There is no protection diode between the DC bus input (J5) and the
DC bus. Applying a voltage with reverse polarity can cause damage to the
power stage.
Always connect ‘+’ to the terminal close to the upper board edge, and GND to
the one close to X6.
Always use a laboratory DC power supply with adjustable current limitation
with this board. Otherwise, in case of software or hardware malfunctions or
false configurations, high currents can flow and damage the power supply
and/or the board and lead to overheating by excessive power dissipation.

4 Programming the internal Flash
In order to program the Flash ROM asynchronously via UART0, the tool “Fujitsu Flash MCU
Programmer for FR” can be used. This tool is available free on the Fujitsu Micros CD-ROM
or Web Site (http://mcu.emea.fujitsu.com/mcu_tool/software.htm)
The following procedure must be followed to perform Flash Programming:
1. Install the FJ FR Flash programmer.
2. Connect the Starterkit (UART 0) to the PC using a 1:1 cable.
3. Start the Flash programmer by double-clicking on the icon
4. Select appropriate MCU type, oscillator frequency, COM-Port, and the path to your
HEX-File (.mhx)
5. Power-off the board
6. Set JP18 to 2-3 (PRG) and power up the Board
7. Press the “Full Operation” button to start programming, press the RESET button
(SW6) and click on ‘OK’.
CAUTION: DO NOT INTERRUPT OR CUT OFF POWER DURING ERASE!!!
8. When download and programming was completed successfully, a message appears.
In case of errors, please check COM-Port configuration, cable connection and jumper
settings.
9. After successful programming, Power off the board and set JP18 back to 1-2 (RUN)
10. Power on the board to start the application

5 Connectors
5.1
Power connector (X6)
The following figure shows the power connection jack X612. This connector is used to
connect an external unregulated DC power supply voltage (8-15V DC) to the evaluation
board.
Shield is connected to positive voltage supply
Connector X6:
Center is connected to ground (GND)
It is recommended to use 9-12V input voltage (depending e.g. on gate driver configuration)
to keep the power dissipation to a minimum.
5.2
DC bus power connector (J5)
The DC bus power can be supplied either by X6 (when JP29 and JP63 are set and
the current is not higher than 3A) or by J5. J5 is a screw terminal for currents up to
15A. Be aware that there is no protection diode for this input on the board. The
voltage input range depends on the jumper settings as described in chapter 3.2.
It is recommended to use an external protection diode with sufficient current
capability in case the used power supply is not protected against reverse current
sourced from the load flowing into the power supply.
Always connect ‘+’ to the terminal close to the upper board edge, and GND to the one
close to X6.
Further, it is strongly recommended to use a laboratory DC power supply with
adjustable current limitation with this board. Otherwise, in case of software or
hardware malfunctions or false configurations, high currents can flow and damage
the power supply and/or the board and lead to overheating by excessive power
dissipation.
5.3
Pin headers (J1-J4)
All pins of the microcontroller are directly connected to J1 to J4 as follows:
Connector

The odd pin numbers are located on the one side and the even pin numbers are located on
the other side of the connector. On the PCB, the corresponding pin numbers of the µC are
written next to the connector pins.

The input signals to J7 have to be conditioned externally. Even though the voltage
measurement inputs are protected by diodes against voltage peaks, care should be taken to
avoid spikes. At least, a series resistor (e.g. 1k) should be present in all MCU ADC
connections. The current sense inputs are connected directly to the MCU analog inputs
AN0-AN4 if the corresponding jumpers (JP43, JP46, JP48, JP51) are set. Refer to chapter 3
