RL78/I1A Chapter 2 System Configuration
Chapter 2 System Configuration
The RL78/I1A DC/DC LED Control Evaluation Board system configuration is
given in the diagram below:
RL78/I1A DC/DC LED Control Evaluation Board System Configuration
Figure 1:
2.1 RL78/I1A DC/DC LED Control Evaluation Board
RL78/I1A DC/DC LED Control Evaluation Board is a demonstration board for
evaluating the new Renesas RL78/I1A family of devices. The device used is the
RL78/I1A (R5F107DEG). The board can be directly connected to the host system
via a USB port. The host system may be used for On-Board debugging or Flash
programming and to allow execution of the Demonstration program on the
RL78/I1A device.
As default, the RL78/I1A is using the 32 MHz internal high-speed oscillator, but
the RL78/I1A DC/DC LED Control Evaluation Board is provided with a connection
for an external 20 MHz oscillator (not fitted) if the user wishes to use a different
clock frequency than that provided by the internal high speed oscillator. An
external low power 32.768 KHz resonator is provided for the sub-clock.
2.2 Host Computer
The USB host interface enables communication to the RL78/I1A DC/DC LED
Control Evaluation Board. The µPD78F0730 78K0 8-bit microcontroller with on-
chip USB interface and the Renesas Electronics virtual UART driver allows
application software to access the USB device in the same way as it would
access a standard RS232 interface. The Renesas Electronics virtual UART driver
appears to the windows system as an extra Com Port, in addition to any existing
hardware Com Ports.
2.3 Power Supply
RL78/I1A DC/DC LED Control Evaluation Board is powered by a 5V DC power
supply and also by USB interface when the µPD78F0730 78K0 microcontroller is
to be used for On-Board debugging, flash programming or virtual UART
communication purpose.
