Figure 1 illustrates the system configuration.
DemoKit-KA1 is a demonstration kit for NEC Electronics’ low-pin-count 78K0S microcontrollers. The
µPD78F9222 is a typical device from this family and was used to realize the DemoKit-KA1, which
connects to the host system via a USB interface cable. The host may be used for programming the
MCU’s flash memory and for executing application programs on the DemoKit-KA1 platform. The
DemoKit-KA1 operates the µPD78F9222 microcontroller at a speed of 8 MHz.
The USB host interface enables communication with the board. The FT232 USB UART chip allows
application software to access the USB device in the same way it would a standard RS-232 interface. To
the Windows operating system, the FTDI's virtual COM port (VCP) driver appears as an extra
communications port, in addition to any existing hardware communications ports. For detailed
specifications for the host interface, refer to section 10, “Connectors and Cables.”
The USB interface supplies 5V of power to the DemoKit-KA1; no separate power supply is needed.
