Know the Board
2.1 Board overview
The ASL5015EVBMST evaluation board features a ASL5x15SHN IC, a highly integrated and flexible Matrix LED
Controller (MLC). The kit is designed to drive 12 LEDs or segments with up to 1.5 A max. current. In a
default application, a microprocessor unit (MCU) controls the devices through a Controller Area Network
(CAN) interface. The MCU controls the dimming profiles of each individual channel. The ASL5x15SHN also
feature several diagnostic readings to allow a detection of errors in the system. A maximum of 9 follower
boards can hang from a single leader board.
2.2 Boards features
The ASL5015EVBMST board features include:
- Control of one ASL5x15SHN Matrix LED Controller (MLC)
- Option to control any NXP ASL5xxxyHN Matrix LED Controller (HVQFN part numbers). All part numbers
are pin to pin compatible.
- Interface connector to the S32K144EVB-Q100, through CAN protocol communication (only available in
- Power supply connector (+12 V and GND). Combined with the S32K144EVB-Q100 interface (only available
in leader EVB)
- Interface connector to a single or multiple LED boards
- Dip switch to select device address in CAN bus
- Interface connector to hang a Follower board (see boards overview section)
- Interface connector to connect to a leader board or other follower board (only available in follower EVB).

Important components on the ASL5015EVBMST
2.5 ASL5015EVBSLAV Evaluation board
The leader 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 follower boards
hanging from the leader board. A maximum of 9 follower boards can hang from a single leader board.

from a single Leader board.
2.6 S32K144EVBQ100 Evaluation board
The ASL5015EVBMST 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.

2.7 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 guide (NDA required).
