2. INTRODUCTION
The board is divided into three sections:
●IO-Link Section
The IO-Link section contains all necessary circuitry to use one CCE4503 (with an adjustable current limit
and slew rate) for IO-Link communication as well as several connectors.
●Sensor Section
The sensor section contains three different sensors to provide a variety of signals and measurement
capabilities (temperature sensor, color sensor and proximity switch).
●MCU Section
The MCU section contains an LPC1347 32-bit ARM Cortex-M3 microcontroller from NXP to control the
CCE4503 Device IC as well as the provided sensors.
For maximum flexibility, the sections can be used separately and independently from each other. This allows to
evaluate the CCE4503 Device IC with any suitable sensor application and MCU or both.
The CCE4503 Evaluation Board is delivered with a CCE4503 with 3.3 V LDO.

3. SYSTEM REQUIREMENTS
The CCE4503 Evaluation Board is ready to use with a preinstalled IO-Link Device Stack.
To get started, the following tools are required:
●Power Supply 24V (IO-Link Master)
●Debug probe (for programming via SWD)

For microcontroller and IO-Link Device IC
■CCE4503 IO-Link Device IC
■M12 connector + terminal blocks
■Three on-board sensors
□Temperature sensor
□Color Sensor
□Proximity sensor / switch
■Independent use of sections (IO-Link, Sensor,
MCU)
5. GETTING STARTED
Programming via SWD
1. Connect debug probe to SWD connector (X1)
2. Set R8 to the desired value (current limit)
3. Power on the Evaluation Board (IO-Link interface L+ = 24V, L- = GND)
4. Start programming with your preferred SDK (Software Development Kit)
6. POWER SUPPLY
The Evaluation Board is supplied via the L+ voltage of the IO-Link interface which has to be 24 V. The IO-Link
interface comprises L+, L- and CQ, and it can be accessed via an M12 connector or terminal clamps. Three
SMAJ33A TVS diodes are used to provide additional protection against high voltage bursts.
At port VDD, a regulated voltage of 3.3 V is generated by a LDO regulator. This regulator supplies the digital I/O
pads of the CCE4503, the MCU and the sensors. VDD can supply additional external components, but the
overall external load at VDD must not exceed 20 mA. The current consumption of the MCU, the sensors and
external components must be below this limit.

7. SECTIONS OF THE CCE4503 EVALUATION BOARD
All sections can be used separately. The connection between the sections can be disconnected by cutting them
open between the cutting marks (see Figure 2). Make sure not to break the evaluation board. To reestablish the
connection, a pin header with 2.54 mm pitch can be used.
Figure 2: Cutting Marks
IO-Link Section
The IO-Link section contains the reference design for using the CCE4503. The current limit and the slew rate
can be adjusted either by using the potentiometer R8, a fixed resistor R14 (not placed) or by connecting ILIM to
GND or VDD. When using R14, please remove jumper on JP6.
A variety of connectors including an M12 a-coded 4-pin connector are placed on the IO-Link section.
Sensor Section
The sensor section contains three sensors which can be used for demonstration and evaluation of the IO-Link
communication.
Temperature Sensor
Features of the temperature sensor:
■SI7055-A20-IM (Silicon Labs)
■I2C interface
■-40 °C to +125 °C (±0.5 °C)

Color Sensor
Features of the color sensor:
■BH1745NUC-E2 (ROHM)
■I2C interface
■16 bit serial output RGBC
For successful measurements, activate LED3 (white LED) to illuminate the object to be measured. In order to
get a better result, keep the object close to the sensor and reduce incident ambient light.
Proximity Sensor / Inductive Switch
Features of the proximity sensor / inductive switch:
■LDC0851HDSGR (Texas Instruments)
■Simple switching output
For successful measurements, the object held over the printed coils should be about the same size as the
printed coils (for example a coin). The switching distance is about 5 mm. LED1 (red LED) signals a detected
object.
MCU Section
All usable pins of the LPC1347 can be accessed via the connectors JP2 and JP3.
In case the on-board sensors are not used, the connection between the MCU section and the sensor section
can be disconnected and the pins used for the sensor section can be used for any other purpose. Note that the
pull-up resistors of the I2C communication are placed on the sensor section.
Connector X1 (JTAG) is used to program the LPC1347.
LED2 (green LED) is used as status LED and can be used for any purpose.
