1 Introduction
The AB-050-FX3-U is designed as a simple and easy to use Starter Board to support users with the first steps
when starting with the Fx3-Series family.
The Starter Board is prepared to hold a V850ES/FK3 device (uPD70F3385). As the largest device of the Fx3-
Series the FK3 offers the complete range of all Fx3 peripherals. Therefore software development for all other Fx3-
Series devices is possible as well. Due to the software compatibility between the different family members porting
of SW from FK3 to smaller devices is possible with only minimum efforts.
Mounting other members of the Fx3-Series on the board also is possible, at the cost of manual replacement of
components and rewiring of signals.
With the NWire Debug interface and the Flash Programming interface for the NEC PG-FP4 Flash Programmer the
standard NEC programming interfaces are directly available.
To enable further application development the board features drivers for five high speed CAN interfaces, eight RS-
232 interfaces and eight LIN bus interfaces.
With on-board voltage regulator and reset generator a simple external DC power supply is sufficient to operate the
board.

Figure 2-1 Board overview
Basically the board is divided into two areas, an ‘Electrical Area’ and a ‘Functional Area’.
In Figure 2-1 the Electrical Area is surrounded in by a red line and the Functional Area is surrounded by a blue line.
2.1.1 Electrical Area
In the center of the Electrical Area a 180 pin SMD pad field is located that any of the F-Series devices can be
assembled to.
On each side of the Device Pad Field a Pin Patch Area is located. In this patch area access is given to
- each pin of the device
- VDD
- VSS
Further more SMD and through hole components can directly be soldered onto the Pin Patch Area to allow simple
networks to be easily built up.
The circuitry available at each pin inside the Pin Patch Area is described in the figure below:

Figure 2-2 Pin Patch Area
A component assembled to the SMD1 field will therefore be connected between the device pin and VSS.
A component assembled to the SMD2 field will be connected between the device pin and VCC.
2.1.2 Functional Area
The Functional Area holds the drivers for RS-232, LIN bus and CAN. Additionally other patch areas are available
as well to directly assemble LEDs, PowerDrivers and connectors to the board.
Note:
For detailed information about the operation of the used RS-232, LIN bus and CAN drivers refer to the related
datasheets of those devices.
2.1.3 Connecting both areas
The Electrical and Functional Areas are not connected to one another except by a common VSS plane.
Nevertheless by use of Jumpers a signal connection between the Electrical Area and the Functional Area is
possible.
The following signals are available on the related jumper fields:

2.2 Reset
A simple Reset Generator using analog circuitry is available.
To connect the on-board Reset generator to the FK3 device close CN52 3-4.
If an external Reset signal shall be connected to the board the following setup must be used:
a) Use TP15 to physically connect the external reset signal.
b) Close CN52 1-2 to connect the external reset signal to the FK3 device.
c) Open CN52 3-4 to disconnect the onboard Reset circuitry from the device.
2.3 NWire connection
The NWire debug cable from a NEC Debug Tool (e.g. MiniCube) can be connected to CN2.
Additionally a KEL connector (CN23) is available to connect third party NWire Debug Tools.
The following jumpers on CN48 must be closed in order to physically connect the NWire signals from CN2 to the
corresponding pins of the FK3 device:
Signal CN48 Pin number

Additionally JP2 must be closed.
2.4 PG-FP4 connection
The programming cable of the PG-FP4 Flash programmer can be connected to CN28.
To program the device via the CSI interface the following jumpers must be closed:
Connector Pin number
JP15 2 – 3

For Flash programming using the PG-FP4 device power can either be supplied by the PG-FP4 or by the AB-050-
FX3.
a) For PG-FP4 power supply open JP2.
b) For AB-050-FJ3 power supply close JP2.
If the clock supply for PG-FP4 programming is not on board, close CN48 Pins 25-26 to supply the clock from PG-
FP4.
2.5 RS-232 / LIN
Close CN49 1 – 2 and 3 – 4 to supply power to RS-232 / LIN bus drivers.
For the LIN bus drivers additionally a VBAT voltage must be supplied. This voltage must be in a range of 5V to 12V.
For the exact specification refer to the Datasheet of the LIN Drivers.
To supply VBAT to the board use either of the two connections:
- Use TP1
- Close JP19 and use Cn16

The RxD pin of the LIN driver (pin #1) is an open drain output. The necessary pull-up resistor in order to interface
to the Fx3 device is not assembled on the board. To enable operation of the RxD signal
- either connect an appropriate pull up resister to the related RxD input pin of the LIN channel, or
- enable the internal Pull-Up resistors available in the Fx3 devices for each LIN input pin.
The corresponding input pin for each RxD pin can be found in Table 6-11.
For additional information on the LIN driver refer to its User’s Manual / Datasheet.
Caution: The RXD reception output pin of the LIN driver (e.g. IC218 pin1) and the RxD reception output pin of
the UART driver (e.g. IC173 pin 12) are physically connected to the same pin on connector CN9 (e.g.
CN9 pin 4).
Therefore
- when using the LIN driver lift the connected UART driver RxD output pin from the PCB.
- when using the UART driver place the connected LIN driver in standby mode or lift the LIN
driver RxD output pin from the board.
2.6 CAN
Close CN49 1 – 2 and 3 – 4 to supply power to the CAN drivers.
Close the following jumpers to physically connect the devices CAN signals to the CAN interface drivers located on
the Functional Area of the board:

3 Mounting the FK3 device on the board
The AB-050-FX3-U boards is shipped with a mounted V850ES/FK3 device.
Nevertheless, if mounting of another V850ES/FK3 device is required at a later time the following guideline is
supplied:
To mount a FK3 device on the AB-050-FX3-U place the package in the top right corner of the SMD area.
As the FK3 with 176 pins is placed on an SMD area with 180 pins 4 pads will not be used. Due to the alignment of
the device in the top right corner two pads in the lowest line and two pads in the left most line remain empty.
Therefore align pin 1 of the device with pin 2 of the SMD pad area.
For details see Figure 3-1 and Figure 3-2.

4 Connecting the Power Supply
Power can be supplied to the board either
a) by directly supplying the device operating voltage, or
b) via the onboard 7805 type voltage regulator.
Direct voltage supply:
A direct supply of the device operating voltage can either be implied by using CN7 to connect VCC (typical +5V for
Fx3 devices) and CN8 to connect VSS (0V), or by using CN1.
As the supplied voltage is directly connected to the device the input voltage must not exceed the specified power
supply voltage range of the assembled device.
Close JP1 1-2 when directly supplying the devices voltage.
Voltage regulator supply:
Use CN1 to supply a stabilized voltage of 6V - 12V to the board. The on board 7805 type regulator will generate the
5V supply of the board.
Close JP1 2-3 when using the on board voltage regulator.
Caution: On CN1 the inner pin connects to VSS and the outer pin connects to VCC.
Applying a voltage to the device outside the specified device operating voltage range may damage
the device!

5 UART / LIN CAN DSUB connectors
To physically connect the Starter Board to other UART / LIN / CAN devices DSUB type connectors are available..
5.1 UART / LIN connectors
To interface the AB-050-FX3-U board to external to UART / LIN devices a 9 pin male D-SUB connector is supplied

6 Mounting other Fx3 devices on the board
Even though the AB-050-FX3-U is prepared for operation of the FK3 device also other devices of the Fx3-Line can
be mounted on the board.
Besides mounting the new device to the board
- the components in the Pin Patch Area must be replaced according to the pin layout of the new device and
- the signals between the device pins and the jumpers connecting the Electrical Area and the Functional
Area must wired manually.
Therefore the following changes must be applied:
6.1 Mounting devices
First the device must be mounted to the PCB. The alignment of the different Fx3-family devices is explained below.
6.1.1 Mounting a FE3 device
To mount a FE3 device on the AB-050-FX3-U place the package in the lower left corner of the SMD area but do
not use the two pins most in the corner. Place pin 1 of the device on pin 2 of the SMD area.
