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 D-
Sub 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.

3 Jumpers and Switches
This chapter describes the jumpers and potentiometers to configure the various features of
the evaluation board. The default settings are shaded in the following tables.
3.1 Operating Mode
JP18 is used to select between serial Flash programming (UART0) and normal run mode.
Jumper Setting Function
1-2 Run
JP18 2-3 Program
3.2 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
© Fujitsu Microelectronics Europe GmbH - 13 -
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.
Jumper Setting Description
Open DC-DC converter ‘+’ used for transceiver supply
JP13 Closed Same supply as MCU used for transceivers (Vcc5)
Open DC-DC converter ‘-’ used for transceiver supply
JP14 Closed Same GND as MCU used for transceivers (GND)
1 - 2 Bypass 15V regulator (Source voltage 10-20V)
JP28 2 - 3 Insert 15V regulator (Source voltage >18V)
Closed common inputs for 15V and 5V regulator
JP29 Open separate inputs for 15V and 5V regulator
Closed Logic supply input enabled
JP31 Open Logic supply input disabled
1-2 5V regulator input connected to VCC15
JP32 2-3 5V reg. input connected to X6 and/or 15V reg. input
Closed connect DC bus voltage to logic and gate driver
supply
JP63 Open J5 supplies only the DC bus
By default, the board is configured for DC bus voltage 0-24V and separate logic supply input
(X6) 10-20V (12V recomm.)
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.

SW6 serves as manual reset button. It is directly connected to the MCUs reset input pin
(INITX, Pin51).
SW7 is connected to the DTTI input of the MCU. When this function is activated in software,
the DTTI input can shut down the PWM output of the MCU (e.g. fault or over-current
protection). Refer to the MB91F265 Series hardware manual for details of the DTTI function
