78K0R – Save It!
3. 78K0R – Save It! system configuration
The 78K0R – Save It! starter kit system configuration is given in the diagram below
Figure 6: 78K0R- Save It! system configuration
3.1 78K0R – Save It!
The 78K0R – Save It! is a demonstration kit for the 78F1009 16-bit low power consumption microcontroller
of the 78K0R family. The demonstration board is connected to the host system via USB interface cable. The
host system may be used for On-Chip debugging by using the IAR C-SPY debugger and to allow execution
of application programs on 78K0R – Save It! starter kit.
78K0R – Save It! runs the microcontroller at 20 MHz operating speed in normal operation mode.
3.2 Host computer
The USB host interface enables communication to the 78K0R – Save It! board. The μPD78F0730 78K0 8-
Bit microcontroller with on-chip USB interface and the NEC virtual UART driver allows application software to
access the µPD78F1009 device in the same way as it would access a standard RS232 interface.
The NEC virtual UART driver appears to the windows system as an extra Com Port, in addition to any
existing hardware Com Ports.
3.3 Power supply via USB interface
The TK-78F0730 board is powered by the USB interface. Optional the power supply can be applied via a
JACK connector which has to be mounted to CN3.
