2. 78K0/Lx3 - See it! system configuration
The
78K0/Lx3 - See it! system configuration is given in the diagram below:
Figure 1: 78K0/Lx3 - See it! system configuration
2.1 78K0/Lx3 - See it!
78K0/Lx3 - See it! is a demonstration kit for the 78K0/LF3 8-Bit microcontroller with integrated LCD
controller. The 78K0/Lx3 - See it! board is connected to the host system via USB interface cable. The
host system may be used for onboard FLASH programming of the 78K0/LF3 internal FLASH memory
and to allow execution of application programs on
78K0/Lx3 - See it! starterkit. Additionally it supports
On-Chip debug functionality by using the IAR C-SPY debugger.
78K0/Lx3 - See it! runs the microcontroller at 8.0000 MHz operating speed. Per default the internal high-
speed oscillator of the 78K0/LF3 device is used. The Sub-clock is provided with 32.768 kHz.
2.2 Host computer
The USB host interface enables communication to the 78K0/Lx3 - See 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
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.
