Introduction
1.3 General Description
The SK-91F467-208PFV supports the FUJITSU 32-bit flash microcontroller MB91F467D.
The starter-kit can be used as a stand-alone development platform, or instead of the flash
MCU MB91F467D, with the emulation system MB2198-01 and the adapter board (MB2198-
300) and the 208 pin probe cable board (PB-91467D-208PFV or PB-91467D-LS-208PFV).
This User Guide is describing PCB version V1.1. The PCB version is printed at the TOP side
of the starter-kit close to MB91F467D MCU [U1].
© Fujitsu Microelectronics Europe GmbH - 9 - FMEMCU-UG-910014-13
SK-91F467D-208PFV V1.1
Introduction
1.3.1 On Board Memory
SK-91F467D-208PFV: The starter-kit SK-91F467D-208PFV includes 32 Mbit (4 MByte)
SRAM memory and 128 Mbit (16 MByte) flash memory on board. The flash can be used with
3.3 V external bus supply voltage only (JP21: 2-3).
1.3.2 MCU Clocks
The board is supplied with a 4 MHz crystal as the main oscillation clock for the MCU. Using
the internal PLL of the MCU, internal clock rates up to 96 MHz can be achieved. The MCU
sub clock is connected to a 32.768 kHz crystal.
1.3.3 MCU Operating Mode
The operating mode of the microcontroller can be selected with the DIP-switch S5.
1.3.4 External Bus interface Connectors
Via DIN 41612 VG96ABC and VG48ABC connectors (external bus interface of the MCU), it
is possible to connect other devices e.g. user applications or Fujitsu graphic device sub
boards.
1.3.5 CAN Bus
Three high-speed CAN-transceivers (PCA82C250) are available to connect all available onchip CAN-controllers to 9-pin D-Sub connectors (X9, X10 and X11). The transceivers
provides differential transmit and receive capability between CAN-controller and CAN-bus.
1.3.6 RS-232 and LIN
Three separate RS-232 transceivers and three separate LIN transceivers are available to
connect the on-chip USARTs to the 9-pin D-Sub connectors.
The RS-232 transceivers generate the adequate RS-232 levels for receive (RXD) and
transmit (TXD) lines. The RTS signal can be shortcut to CTS using jumpers (some PC
software needs this connection).
Either the DTR line or the RTS line of X1, X4 or X8 connectors can be selected to generate
a system reset.
The LIN transceivers (TLE6259) generate the adequate levels to drive the bus line in LINsystems for automotive and industrial applications.
1.3.7 MCU Pins
All 208 pins of the microcontroller are connected to the edge connectors J1, J2, J3 and J4
and are directly available to the user.
1.3.8 User Buttons
There are four push buttons on board, which can be connected to input-ports of the
microcontroller. Some ports may support additional functions like external interrupts (INT0,
INT1 and INT2) and trigger for the Reload Timer or for the Input-Capture Unit (TIN0 / ICU0).
One additional button is reserved as system-reset-button to reset the MCU, but it is possible
to disconnect the RST-port with JP54.
It is possible to connect with DIP-switch S3 eight port input switches at S4 to the MCU port
P26. All eight ports can be switched separately to use e.g. only four ports as input.

SK-91F467D-208PFV V1.1
Introduction
1.3.9 User LEDs and Optional LCD
Sixteen user-LEDs are connected via two pull-down resistor networks to port P25 and to port
P16. Parallel to the LEDs on port P25, the connector J6 can be used to connect a standard
alphanumeric display. The resistor networks RN2 and RN3 can be removed to free the ports.
1.3.10 Power Supply
The four on-board step-down switching regulators allow the user to connect an unregulated
DC input voltage between +9 V to +12 V (max. 2000 mA) to the starter-kit. The switching
regulators provide the voltages of 5 V(3 A), 3.3 V(3 A), 2.5 V(1.5 A) and 1.8 V(1.5 A) on the
starter-kit. These voltages give also the possibility to connect an optional graphic-controller
starter-kit to the board. The switching regulators are short circuit protected and provide a
thermal shutdown.

Installation
2 Installation
Remove the board carefully from the shipping carton.
First check whether there are any damages before power on the starter-kit.
To supply the starter-kit use the delivered plug-in AC-DC Adapter (UPA 2000). Select the AC
plug adapter suitable for your country power sockets
Figure 2-1 AC plug adapter
and insert this adapter in the connection terminal on the AC-DC adapter.
Figure 2-2: AC plug adapter selection
Check the selected output DC voltage of the AC-DC plug-in adapter at the voltage selection
key. It should be 9 V! Change the output voltage only in a powered-down condition!
Figure 2-3: DC voltage selection
Select the low voltage adapter suitable to the power connector X5 at the SK-91F467D208PFV and plug it to the connecting socket in the right orientation (‘+’ connected to shield
and ‘GND’ connected to centre pin).
Figure 2-4: Low voltage adapter selection
Now connect the DC low voltage adapter to the starter-kit and plug in the plug-in power
supply to a power socket. The SK-91F467D-208PFV can be turned on with the on board
power switch S8 (or S9).

SK-91F467D-208PFV V1.1
Installation
For the power supply of the SK-91F467D-208PFV a DC input voltage of 9V – 12V is
recommended. The positive voltage (+) must be connected to the shield, and ground
(GND) must be connected to the centre of the connector X5!
After power-on of the SK-91F467D-208PFV, the four red power-on LEDs D24 (5 V), D30
(3.3 V), D34 (2.5 V) and D40 (1.8 V) should be light. The reset LED D18 should be off.
The starter-kit is delivered with programmed Softune Workbench (SWB) Monitor Debugger
in the external flash. The SWB Monitor Debugger checks also the external SRAM access at
CS1. In case of successful access to external SRAM the LED D1, D4 and D8 are on.
To use the SWB Monitor Debugger, the CPU mode selection must be set to the External
Reset Vector mode by setting DIP switch S5 to (On, Off, Off, Off), which is the delivery state.
To use the MCU with the internal flash, which is normally required for the final application,
the CPU mode selection must be set to the Internal Reset Vector mode by setting DIP switch
S5 to (Off, Off, Off, Off)

Installation
2.3 Software Installation
2.3.1 Installation of Softune Workbench
With the “SK-91F467D-208PFV” Fujitsu supplies a full working development environment
called Softune Workbench V6. The Softune Workbench also supports the SWB Monitor
Debugger which is pre-programmed into the external flash memory of the “SK-91F467D208PFV”. To develop own software and to work with the SWB Monitor Debugger of the “SK91F467D-208PFV” the Softune Workbench development environment must be installed first.
Follow the instructions for successful installation of the Softune Workbench.
1) Before starting the installation setup ensure that you are logged in with administrator
or poweruser permissions, otherwise the Softune Workbench installation will fail! Be
aware that Softune Workbench does not support multi-user support. Therefore
install- and user login must be the same.
2) Browse on the starter-kit CD-ROM into the directory Software\SWB_Install and start
the FRSTA*.exe.
3) Follow the installation instructions.
4) For the default installation path it is recommended to use c:\Softune32.
5) After the installation is finished. The FR Family Softune Workbench can be started
via the Windows “Start” menu.
Figure 2-7: Softune Workbench start menu location
6) When Softune Workbench was started the following window will be shown.

3.2 Power Supply
There are four on-board switching regulators to provide the voltages 5 V, 3.3 V, 2.5 V and
1.8 V on the starter-kit. With the power ON/OFF-switch S8 or S9 (S9 is a soldering option to
use a different switch), the main input voltage from DC-connector X5 will be connected to the
Vin voltage of the board. The Vin voltage supplies the switching regulators.

There is a triple supply monitor on-board, which monitors three of the four DC output
voltages and generates a system reset, in case with wrong levels of the on board voltages.
5 V and 3.3 V are always monitored and the third monitored voltage can be selected with the
solder jumpers JP42 and JP43.
With JP68 it is possible to select the whole board supply voltage Vcc to 5 V or 3.3 V
