V850ES/Fx3 – CAN it!
1. Introduction
V850ES/Fx3 – CAN it! is a demonstration kit for the V850ES/Fx3 32-bit RISC microcontroller. It supports
On-Board debugging via the TK-V850 interface (monitor debugging) or via N-Wire. Additional FLASH
programming and real time execution of application programs based on the V850ES/FG3 32-bit RISC
microcontroller is supported by the V850ES/Fx3 – CAN it! demonstration kit. The board is prepared to be
connected to user hardware parts such as digital I/O or analogue signals.
1.1 Main features of V850ES/Fx3 – CAN it!
• Easy to use device demonstration capabilities
V850ES/Fx3 – CAN it! contains elements to easily demonstrate simple I/O-functions, i.e. push
buttons, 12*2 character LC display, LED output, AD reference voltage, I/O lines, UART serial
interface, LIN and CAN serial interfaces.
• TK-V850 debugging
The V850ES/Fx3 – CAN it! supports an On-Board debug function by using the IAR C-SPY debugger
and the UART / USB interface without a need of additional debug hardware. It allows FLASH
programming and supports standard debug functions i.e. code execution, single stepping, software
breakpoints, memory manipulation etc.
• N-Wire debugging
The V850ES/Fx3 – CAN it! is prepared to be equipped with a 20-pin connector in order to connect
the QB-V850MINI-EE On-Chip debug emulator to use On-Chip debug function of the V850ES/FG3
device. Please note, the QB-V850MINI-EE is separate product from NEC and it is not included in this
starterkit package.
• Power supply via USB interface
V850ES/Fx3 – CAN it! is powered via USB interface, no separate power supply is needed.
• Character LCD module
V850ES/Fx3 – CAN it! provides a 12*2 character LC display, allowing the implementation of human /
machine interfaces, comfortable input / output functions, output of measurement values, output of
status information etc.
• FPL, FLASH programming software
A windows based FLASH programming software allows to select and download application programs
to the V850ES/Fx3 – CAN it! board for evaluation purposes.
• Analogue to digital signal conversion is supported
• Various input / output signals available, such as
° I/O ports prepared to be connected to user hardware
° Timer input / output signals
° Two or three wire serial I/O
° UART interface, via USB UART chip FT232
° High Speed CAN bus interfaces with transceiver PCA82C250
LIN bus support, via TJA 1020 transceiver
°
° 16 analogue input lines
° Temperature sensor KTY13-5
° 4 I/O ports connected to LED
° 2 push buttons prepared for external interrupt generation
• The IAR Embedded Workbench for V850 and the IAR C-SPY debugger / simulator are included. This
package is restricted in such that maximum program code size is limited to 16 kByte.
• Full documentation is included for the NEC V850ES/FG3 microcontroller, IAR Systems Embedded
Workbench, IAR Systems C-SPY debugger / simulator and the NEC FPL FLASH programming
software.

V850ES/Fx3 – CAN it! board is connected to the host system via a USB interface cable. The host system
may be used for On-Board debugging of application software by using the IAR C-SPY debugger or the
programming of the V850ES/FG3 internal FLASH memory by using the FPL programming GUI, to allow
execution of application programs on the V850ES/Fx3 – CAN it! starterkit hardware.
The V850ES/Fx3 – CAN it! is equipped within an 4.0000 MHz crystal oscillator. This allows running the
V850ES/FG3 device at a speed of 32 MHz by using the internal PLL of the microcontroller.
2.2 Host computer
The USB host interface enables communication to the V850ES/Fx3 – CAN it! board. The USB UART chip
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 addition to any existing hardware Com Ports.
2.3 Power supply via USB interface
V850ES/Fx3 – CAN it! is powered by USB interface, no separate power supply is needed. The USB
interface provides the V850ES/Fx3 – CAN it! board with 5V supply voltage.
