78K0R/Lx3 – Sense it!
3. 78K0R/Lx3 – Sense It! system configuration
The 78K0R/Lx3 – Sense It! starter kit system configuration is given in the diagram below
Figure 3: 78K0R/Lx3- Sense It! system configuration
3.1 78K0R/Lx3 – Sense it!
The 78K0R/Lx3 – Sense It! is a demonstration kit for the 78F1508 16-bit 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/Lx3 – Sense It! starter kit.
78K0R/Lx3 – Sense 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/Lx3 – Sense 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 µPD78F1508 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-78K0R/LH3+LCD board is powered by the USB interface. Optional the power supply can be applied
via the connectors J2 (VDD) and J3 (GND) or an external battery mounted to J4 on the back side of the
starter kit board.
