- Environments where static electricity or electrical noise is readily generated.
Such influences can lead to electric shock or product failure.
If liquid enters the board, disconnect the power supply, and consult your dealer or Renesas
Electronics sales representative.
Even if the unit appears to be dry, internal moisture may remain.
Do not directly touch LEDs on this board.
Doing so may cause product failure.
Caution
To prevent static electricity damage, guard against static discharge when touching metal
parts such as the connector.
Static electricity can cause product failure.

RL78/I1A
RENESAS MCU
Chapter 1 Introduction
The RL78/I1A DC/DC LED Control Demonstration Kit comes with the RL78/I1A
DC/DC LED Control Evaluation Board and a DVD containing all the appropriate
software tools and documentation.
The RL78/I1A DC/DC LED Control Evaluation Board is an evaluation board for
the new Renesas RL78/I1A microcontroller. It supports On-Board debugging,
flash programming, and is intended to demonstrate the RL78/I1A MCU’s special
features dedicated to LED lighting system control.
1.1 Main features of RL78/I1A DC/DC LED Control
Evaluation Board
LED lighting system control demonstration capabilities
RL78/I1A DC/DC LED Control Evaluation Board features circuits to perform
constant current control of 3 LED channels (RGB LEDs) in order to
demonstrate the special 16-bit Timers KBn (n = 0, 1, 2).
oBuck topology
o350 mA maximum current per channel
4 types of dimming control interface supported
o3 ch. analog volume control interface (for standalone evaluation)
oDALI protocol communication interface
oDMX512 protocol communication interface
oIR remote control interface
Easy to use device demonstration capabilities
RL78/I1A DC/DC LED Control Evaluation Board contains elements to easily
demonstrate simple I/O-functions (i.e. LED output, I/O lines, UART serial
interface) together with the other key functions such as Real Time Clock (RTC),
ADC and Timers.
Power supply via 5V DC connector
RL78/I1A DC/DC LED Control Evaluation Board is powered via a 5V DC jack
connector. This power supply is used to power the RL78/I1A as well as the LEDs.
When On-Board debug function is used, the USB interface is used to power the
µPD78F7030 78K0 USB microcontroller.
On-Board debug function
RL78/I1A DC/DC LED Control Evaluation Board supports an On-Board debug
function by using the IAR C-SPY debugger, without the need of additional debug
hardware. It allows flash programming and supports standard debug functions
such as code execution, single stepping, software breakpoints, memory
manipulation etc. (The E1 emulator can also be used for on-chip debugging)
WriteEZ5, Flash programming software
Windows based Flash programming software allows the user to select and
download application programs to the RL78/I1A DC/DC LED Control Evaluation
Board for evaluation purposes via USB.
Applilet EZ for HCD Controller, Automated software generation tool
Software tool used to generate full projects for different compilers.
