Introduction
This document describes the features and hardware details of the White LED Card (inLight_WhiteLED_v4)
designed to work with Infineon‟s XMC1200 CPU Card. This board is part of Infineon’s XMC1000 LED Lighting
Application Kit.
1
Overview
The White LED Card is an application expansion card of XMC1000 LED Lighting Application Kit. The White LED
Card along with a XMC1200 CPU Card demonstrates the LED lighting capabilities of XMC1200. The main use
case for this application card is mainly to demonstrate the smooth brightness control of XMC1200 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 White LED Card is equipped with the following features
• Connection to XMC1200 CPU Card via 2x30 pins (0.8mm pitch) SAMTEC HSEC8 connector
• Brightness control of four LED strings
• DALI interface with isolation
• Temperature sensing
• Ambient light sensing
• 433MHz RF receiver
• +5V Power supply via SAMTEC 2x30pins connector
• +24V external connection to supply power to the four LED drivers (BCR450)

Hardware Description
The following sections give a detailed description of the hardware and how it can be used.

2.1
White LED Card
White LEDs
The White LED Card supports brightness control of four LED strings, each string consists of five White LEDs
(LUW_E6SG) on board.The forward voltage VF is 3.3 V @ IF=30mA.
The card implements brightness control through BCCU module of XMC1200. The BCCU module used four
channels to drive four LED drivers (BCR450) which control the current flow through the White LED string. The
+24V power supply to the LED drivers is provided from an external connector J1.

Digital Addressable Lighting Interface (DALI)
The White 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 on XMC1200 CPU Card to receive DALI data.
