1. Get Started
The NXP analog product development boards provide an easy-to-use platform for
evaluating NXP products. The boards support a range of analog, mixed-signal, and power solutions.
They incorporate monolithic integrated circuits and system-in-package devices that use proven
high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced
component counts, lower cost, and improved performance in powering state-of-the-art systems.
This page will guide you through learning about how to set up the ASL5115EVBMST evaluation board
master and slave ASL5115EVBSLAV.

2. Know the Board
2.1 Board overview
ASL5115EVBSLAV features the ASL5115SHN. The ASL5xxxyHz family is a fully featured and flexible Matrix LED
Controller (MLC). It provides a cost-effective design solution, specifically targeting advanced
automotive exterior lighting applications. ASL5115SHN is controlled in direct mode, where the
microcontroller updates the PWM information of each channel in a determined cycle. ASL5115SHN offers a
12-bit resolution in the PWM output, ensuring a smooth dimming performance to avoid glitches in the
2.2 Boards features
The ASL5115EVBSLAV board features include:
- Interface connector to attach the ASL5115EVBMST Matrix LED Controller (MLC)
- ASL5115EVBSLAV can be daisy chained with up to 9 slave boards that hang from a single Master board
- Dip switch to select device addresses
- Populated with ASL5115SHN Matrix LED controller

2.3.1 ASL5115EVBSLAV Evaluation board
Modular Slave EVB for Matrix LED Controller (MLC) ASL5115SHN connects to
2.3.2 ASL5115EVBMST Evaluation board
The master board is populated with one UJA1163 System Basic Chip (SBC) IC, to enable the communication
with the microcontroller or Vector CANoe through CAN (FD) protocol, and to supply the MLC populated in
the same board, together with the MLCs populated in the slave boards hanging from the master board. A
maximum of 9 slave boards can hang from a single master board.
2.3.3 ASL5115EVBSLAV Evaluation board daisy chain
Example of connection between a master board and a slave board. Up to 9 slave boards can hang from a
single Master board. If there is one or several slave EVBs in the system, create a chain with the master
board using connectors X1 and X3. Also attach customer LED boards to the slaveEVBs.
2.4 Accessory boards
2.4.1 S32K144EVBQ100 Evaluation board
The ASL5115EVBMST is compatible with the S32K144EVBQ100. The S32K144EVB-Q100 provides the control signals
(through CAN (FD) communication) for the ASL5x15SHN devices. When used with the GUI, the S32K144EVBQ100
drives the channels in the way as selected on the GUI. The S32K144EVB-Q100 can also be used as a system
processor to create standalone applications or prototype systems.
2.4.2 ASL45XASLX41 - Multichannel LED driver system Evaluation Board
The ASLx500SHN and ASLx41xSHN Evaluation Board (EVB) features the ASL4500SHN, a highly integrated and
flexible four-phase DC-to-DC boost converter IC and two ASL3416SHN, a three-channel buck mode LED driver
IC delivering constant average DC current. The kit is designed to drive six LED strings with 150 mA to
1.6 A and 2 V to 60 V LED string voltage. In a default application a microprocessor unit (MCU) controls
the devices through a serial peripheral interface (SPI).
The ASL5x15EVBMST is only connected to the CAN physical bus of the S32K144EVBQ100 and to the LEDs. The
ASL5x15EVBMST EVB is not directly connected to the ASL45XASLX41. More information on the connection of
the ASL45XASLX41 EVB can be found in the ASL45XASLX41 User
