1. Introduction
78K0/Lx3 - See it! is a demonstration kit for the 78K0 L_Series 8-bit microcontrollers with integrated LCD
controller. It supports On-Board debugging, FLASH programming and real time execution of application
programs based on the 78K0/LF3 microcontroller. The board is prepared to be connected to user
hardware parts such as digital I/O or analogue signals.
1.1 Main features of 78K0/Lx3 - See it!
•Easy to use device demonstration capabilities
78K0/Lx3 - See it! contains elements to easily demonstrate simple I/O-functions, i.e. navigator switch,
224 segment LCD panel, temperature sensor, IR receiver module, I/O lines, UART serial interface
etc.
•TK-78 debugging
The 78K0/Lx3 – See 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.
•OCD debugging
The 78K0/Lx3 – See it! is prepared to be equipped with a 10-pin connector in order to connect the
QB-MINI2 On-Chip debug emulator to use the On-Chip debug function of the 78K0/LF3 device.
Please note, the QB-MINI2 is separate product from NEC and it is not included in this starterkit
package.
•Flexible power supply
The 78K0/Lx3 - See it! supports a flexible configuration of it’s power supply. The board can be
powered by the USB interface, the QB-MINI2 On-Chip debug emulator as well by an external power
supply.
•LCD panel
78K0/Lx3 - See it! provides a 224 segment LCD panel, allowing the implementation of
human / machine interface, comfortable input / output functions, output of measurement values,
output of status information etc.
•WriteEZ3, FLASH programming software
A windows based FLASH programming software allows to select and download application programs
to the 78K0/Lx3 - See it! board for evaluation purposes.
•Various input / output signals available, such as
°I/O ports prepared to be connected to user hardware
°224 segment LCD panel
°Timer input / output signals
°Two or three wire serial I/O
°UART interface, via USB UART chip FT232
°Eight channel 10-bit A/D converter
°Three channel 16-bit ∆∑ A/D converter
°IR receiver module RPM7138
°Temperature sensor S-8120C
°Navigation switch prepared for key interrupt generation
•The IAR Embedded Workbench for 78K and the IAR C-SPY debugger / simulator are included. This
package is restricted in such that maximum program code size is limited to 4 kByte of program code.
•Full documentation is included for the 78K0/LF3 microcontroller, IAR Systems Embedded
Workbench, IAR Systems C-SPY debugger / simulator and the WriteEZ3 FLASH programming
software
