Warning

Cautions

Do not use or store this board in any of the following locations.

- Environments with excessive water, humidity, steam, dust, fume, etc.

- 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.

Be careful to avoid burns.

Parts of the board, especially the area enclosed by a dotted line, become extremely hot.

Do not look directly at LEDs on this board.

Doing so may weaken eyesight.

Use this board with the LED mounting surface back.

Use a specified AC adapter.

Using an AC adapter other than that specified causes the product to fail, heat up, or catch fire, or

electric shock.

Warning

Do not touch directly LEDs on this board.

Doing so may cause a 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.
