2. V850ES/Jx3-H - Plug it! system configuration
The V850ES/Jx3-H - Plug it! system configuration is given in the diagram below:
Figure 1: V850ES/Jx3-H - Plug it! system configuration
2.1 V850ES/Jx3-H - Plug it!
V850ES/Jx3-H - Plug it! is a USB-demonstration kit for the 70F3760 32-bit microcontroller of the V850
family. The demonstration board is connected to the host system via USB interface cable. The host
system may be used for On-Chip debugging by using the IAR C-SPY debugger and to allow execution of
application programs on the V850ES/Jx3-H - Plug it! starterkit.
2.2 Host computer
The USB host interface enables communication to the V850ES/Jx3-H - Plug it! board. The µPD78F0730
78K0 8-Bit microcontroller with on-chip USB interface and the NEC virtual UART driver allows application
software to access the USB device in the same way as it would access a standard RS232 interface.
The NEC virtual UART driver appears to the windows system as an extra Com Port, in addition to any
existing hardware Com Ports.
2.3 Power supply via USB interface
The V850ES/Jx3-H - Plug it! board is powered by the USB interface. Optional the power supply can be
applied via the connectors CN4 or J1.

V850ES/Jx3H – Plug it!
3. V850ES/Jx3-H - Plug it! components
The V850ES/Jx3-H - Plug it! board is equipped with USB-connector and with several connectors in order
to be connected to host computers, FLASH programmer or any external target hardware.
Figure 2: V850ES/Jx3-H - Plug it! Components
Some of the V850ES/Jx3-H - Plug it! components are free for user application hardware and software.
Please read the user’s manual of the 70F3760 device carefully to get information about the electrical
specification of the available I/O ports before you connect any external signals to the
V850ES/Jx3-H - Plug it! board.

V850ES/Jx3H – Plug it!
3.1 SW1, Configuration Switch (DIP-Switch)
The different operation modes of the V850ES/Jx3-H - Plug it! board can be set by switch SW1. The bits
1-4 of DIP switch SW1 are for the mode setting of the board, bits 5-8 are connected to the pins
“P78/ANI8”, “P79/ANI9”, “P710/ANI10” and “P711/ANI11” of the V850 microcontroller and can be used
for user application purpose.
The V850ES/Jx3-H - Plug it! starterkit can be used in the following operation modes:
- On-Board debug mode
oStart a debug session using the On-Board debug interface
- Flash-Programming Mode
oProgram an application to the build-in flash memory of 70F3760 by WriteEZ1-
programmer
- Stand alone mode
oRun a program stored in built-in flash memory of the 70F3760 device
- N-Wire debug mode
oStart a debug session using an N-Wire emulator, e.g. MINICUBE

3.12 USB1, serial interface connector
This interface allows connecting the IAR C-SPY debugger to the V850ES/Jx3-H - Plug it! board in order
to use the On-Board debug function. The interface supports On-board FLASH erasing / programming and
standard debug features like code execution, single stepping, breakpoints, memory manipulation etc.
The power supply of the V850ES/Jx3-H - Plug it! board is also provided by the USB1 connector.

For connection with the host machine, use a USB cable (Mini-B type). For confirmation,
NEC Electronics used only the USB cable delivered with the V850ES/Jx3-H - Plug it! board.
3.13 USB2, universal serial bus connector
The interface allows connecting the built-in USB function controller of the μPD70F3760 with a host
system. It is also possible to provide the power supply of the V850ES/Jx3-H - Plug it! board by the
USB2 connector.
For connection with the host machine, use a USB cable (Mini-B type). For confirmation,
NEC Electronics used only the USB cable delivered with the V850ES/Jx3-H - Plug it! board.

3.14 Layout of solder-short pads
Several pins of the 70F3760 microcontroller are connected to solder short-pads. The pads can be
opened by the user to add user specific functions. The signal connected to each solder-short pad is
printed on the V850ES/Jx3-H - Plug it! board. To open a circuit, cut the narrow part of the pad with a knife.
To short a circuit again, join the separated pad with a soldering iron.

4. On-Chip debugging
The V850ES/Jx3-H - Plug it! board offers two possibilities to use On-Chip debugging (OCD). The TK-
V850 On-Board debug function of V850ES/Jx3-H - Plug it! allows On-Chip debugging without a need of
external debug hardware. Within this mode the default USB connection to the Host computer based on
the virtual UART driver is used as debug interface. All standard debug functions are available in the On-
Board debugging mode like FLASH programming / downloading, code execution, single stepping,
breakpoints, memory manipulation etc.
Additionally V850ES/Jx3-H - Plug it! supports the QB-V850MINI On-Chip debug emulator in order to use
On-Chip debug function of the 70F3760 device. The system configuration for On-Chip debugging is
shown in figure below.
