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.

2. V850ES/Fx3 – CAN it! system configuration

The V850ES/Fx3 – CAN it! system configuration is given in the diagram below:

Figure 1: V850ES/Fx3 – CAN it! system configuration

2.1 V850ES/Fx3 – CAN it!

V850ES/Fx3 – CAN it! is a demonstration kit for the V850ES/FG3 32-Bit RISC microcontroller. The 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.
