Colour LED Card
Introduction
This document describes the features and hardware details of the Colour LED Card (inLight_RGB_v3) designed
to work with Infineon‟s XMC1200 CPU Card. This board is part of Infineon‟s XMC1000’s LED Lighting
Application Kit.
1
Overview
The Colour LED Card is an application expansion card of XMC1000 LED Lighting Application Kit. This
application card along with a XMC1200 CPU Card demonstrates the LED lighting capabilities of
XMC1200/XMC1300. The main use case for this application card is to demonstrate the smooth colour control of
XMC1200/XMC1300 device including the toolchain. The focus is safe operation under evaluation conditions.
The board is not cost optimized and cannot be seen as reference design.
1.1
Key Features
The Colour LED Card is equipped with the following features
• Connection to XMC1200/XMC1300 CPU Cards via 2x30 pins (0.8mm pitch) SAMTEC HSEC8
connector
• RGB control of three independent LEDs (OSRAM LRTB-G6SF)
• DALI interface with isolation
• DMX512 interface without isolation
• Ambient light sensing
• 433MHz RF receiver
• +5V Power supply via SAMTEC 2x30pins connector
• +12V external connection to supply power to the 3 LEDs

RGB LEDs
The Colour LED Card supports individual control of three OSRAM RGB LEDs (LRTB-G6SF), namely LED1,
LED2, LED3, on board.The forward voltage VF is 2 ~ 3.2 V @ IF=20mA.
The card implements brightness and color control through BCCU module of XMC1200. The BCCU module has
9 channels to drive 9 LED drivers (BCR421) which control the current flow through the Red, Green and Blue
LEDs of the three OSRAM LED module.

Digital Addressable Lighting Interface (DALI)
The Colour LED Card supports DALI interface on board with two optocoupler (SFH6186-2) which provide level
shifting and voltage isolation between the DALI network and the microcontroller’s power supply. The DALI
connector X3 consists of a DATA+ and DATA- signal pair.
Note: Please remove R105 of XMC1200 CPU Card when using DALI for receiving data.

DMX512/ Remote Device Management (RDM)
The Colour LED Card supports DMX512 interface on board with RS-485 transceiver (MAX481CSA). The
DMX512 connector X4 consists of a 120 ohms termination resistor between DATA+ and DATA- and a Ground
pin.
Note: There is NO isolation between external DMX512 signals and the XMC1200’s DMX512 interface signals.

Power
Power input (5V) to the Application card is supported through the SAMTEC 2x30pins connector. VAREF and
VAGND supply power to 433MHz RF Receiver and Light sensing transistor. VDD and GND provide power to
the DALI and DMX512 circuitry.
VIN supply power to the three RGB LEDs and is shorted to VDD via a zero ohm resistor R1. However, user
could also connect VIN to external power supply by removed R1, soldered zero ohm resistor R8 and connected
external power supply to connector X2.
