Get Started with the ASL5015EVBMST

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 leader EVB)
• 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).

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.

Example of connection between a leader board and a follower board. Up to 9 follower boards can hang 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).

2.8 Additional board support

Board block diagram, board description, test points and additional board descriptions and images are available in the User Guide. Refer to UM11224 - ASL5x15 Evaluation Boards - User Guide [English]

3.1 Hardware configuration

A full system configuration is completed with the ASL5015EVBMST wired with cable harness for power supply and CAN (FD) communication to the S32K144EVBQ100 associated by the connectors on the ASL45XASLX41 Multichannel LED board. Can also be configured with up to 9 ASL5115EVBSLAV follower boards not shown. Customer ca n configure using their own LED board.

3.2 Configuration image

To start working with the ASL5x15EVB, the following connections and setup must be performed:

1. Connect the ASL5015EVBMST to the S32K144EVB. Do not forget to supply S32K144EVB-Q100 with 12 V, to enable the CAN communication through the SBC
2. With power turned off, attach S32K144EVB-Q100 12 V DC power supply to ASL5015EVBMST’s supply terminals
3. Attach an LED board (example shown in image) to the ASL5015EVBMST. Additionally, if there is one or several follower EVB in the system, create a chain with the leader board using connectors X1 and X3
4. (Optional) If using the optional ASL45XASLX41: attach the S32K144EVBQ100 to ASL45XASLX41, and supply the LED boards with any of the available buck outputs
5. Plug the USB cable from the mini connector end into the S32K144EVB-Q100
6. Plug the USB cable standard connector end into the computer
7. Turn on the power supply. The supply indicator LED (Red LED in ASL5x15EVBMST) (Green LED3 and LED4 in ASL45XASLX41) shall light up
8. (Optional) Use GUI to drive all the evaluation boards (S32K144EVB-Q100, ASL45XASLX41 and all MLC's evaluation boards)
9. (Optional) Use Vector CANoe software to drive MLC's evaluation boards
10. (Optional) Use your own software, microcontroller and LED driver module to evaluate the NXP's Matrix LED Controller using its EVB
