2. EB-V850ES/HG2-EE system configuration
The EB-V850ES/HG2-EE system configuration is given in the diagram below:
Figure 1: EB-V850ES/HG2-EE system configuration
2.1 EB-V850ES/HG2-EE
EB-V850ES/HG2-EE is a demonstration kit for the NEC H_Line V850ES family devices. As a typical
microcontroller from H_Line family the V850ES/HG2 device (µPD70F3707) is used. The board is
connected to the host system via a USB interface cable. The host system may be used for On-Boa rd
debugging or FLASH programming and to allow execution of application programs on the V850ES/HG2
device.
The EB-V850ES/HG2-EE board is equipped with an 5.0000 MHz oscillator, allows running the
V850ES/HG2 microcontroller at 20MHz. Sub-clock is provided with 32.768 kHz.
2.2 Host computer
The USB host interface enables communication to the EB-V850ES/HG2-EE board. Th e USB UART chi p
FT232 allows application software to access the USB device in the same way as it would access a
standard RS232 interface. The FTDI's Virtual COM Port (VCP) driver appears to the windows system as
an extra Com Port, in additi on to any existing hardware Com Ports.
2.3 Power supply via USB interface
EB-V850ES/HG2-EE is powered by USB interface, no separate power supply is needed. The USB
interface provides the EB-V850ES/HG 2-EE board with 5V supply voltage.
12
EB-V850ES/HG2-EE
3. EB-V850ES/HG2-EE board components
The EB-V850ES/HG2-EE board is equipped with push buttons, a 7 segment LED and several connectors
in order to be connected to user hardware or host computers.
Figure 2: EB-V850ES/HG2-EE board connectors, switches and LED’s
Some of the EB-V850ES/HG2-EE components are free for user application hardware and software.
Please read the user’s manual of the V850ES/HG2 device carefully to get information about the
electrical specification of the available I/O ports before you connect any external signal to the EB-
V850ES/HG2-EE board.

a 5V AC adapter. Also in this case the soldering bridges DCVDD1 and DCVDD2 must be closed.
Note: When using an external power supply, please open jumper JP1!

3.12 Soldering Bridges
Some terminals of the V850ES/HG2 device can be customized by opening respectively closing the
corresponding soldering bridge. By opening the soldering bridge the connection to the onboard circuit is
cut. Accordingly, the corresponding signals can be used for external user hardware using the connectors
CN1 and CN2. F o r m o r e de t a i ls plea se r efer t o t h e bo ard schemat i c s, pa ge s 80- 8 1 .
