NXP Semiconductors ASL5115EVBMST

Overview

ASL5115EVBMST from NXP Semiconductors is a master evaluation board for the ASL5115SHN Matrix LED Controller (MLC), designed to drive up to 12 LED segments at ≤1.5 A per channel via CAN(FD) interface and support daisy-chained slave boards (up to 9). It integrates the UJA1163 System Basic Chip (SBC) for CAN communication and local power supply, and features dip-switch address configuration for multi-node CAN bus operation.

For engineers reviewing the ASL5115EVBMST datasheet, ASL5115EVBMST pinout, ASL5115EVBMST application, or ASL5115EVBMST equivalent, this board enables rapid validation of automotive matrix LED lighting architectures - including SMART PWM and Direct PWM control modes, Limp-Home Mode (LHM) diagnostics, and MTP register programming - using S32K144EVB-Q100 host control and GUI SW491501.

Technical Context

The ASL5115EVBMST implements a master node in a distributed matrix LED control system, hosting one ASL5115SHN IC and UJA1163 SBC. It provides CAN(FD)-based command routing, 12 V input regulation, and configurable device addressing via 5-bit dip switch (A0–A4) tied directly to the MLC's address pins.

It supports both SMART PWM (ASL50xx) and Direct PWM (ASL51xx) variants through software-selectable GUI pages, with hardware-level compatibility across the ASL5x15SHN/FHN family. The board routes all 16 switch outputs (SW0–SW15), NTC, and ID signals to connector X2 for direct connection to LED load boards.

FAQ

What is the primary function of the ASL5115EVBMST?

The ASL5115EVBMST is a master evaluation board for the ASL5115SHN Matrix LED Controller, enabling engineers to prototype and validate automotive adaptive lighting systems. It hosts the ASL5115SHN IC and UJA1163 SBC, provides CAN(FD) communication, powers up to nine slave boards, and supports full GUI-driven configuration of PWM channels, diagnostics, and MTP registers - all as part of the ASL5x15 evaluation ecosystem.

Which microcontroller is required to operate the ASL5115EVBMST?

The ASL5115EVBMST is designed to interface with the S32K144EVB-Q100 evaluation board via CAN(FD), which acts as the host controller. The S32K144EVB-Q100 runs firmware that bridges PC-based GUI commands (SW491501) to the ASL5115EVBMST, enabling real-time channel control, diagnostics, and Limp-Home Mode testing - no additional MCU is needed beyond this validated combination.

Does the ASL5115EVBMST support both SMART PWM and Direct PWM modes?

Yes, the ASL5115EVBMST supports both modes via software selection in the NXP GUI (SW491501): "SMART MLC" page for ASL50xx-compatible configurations and "Direct PWM Matrix LED Controller – ASL51xx" page for ASL51xx-specific register mapping and timing control - reflecting the dual-mode capability of the underlying ASL5115SHN IC.

How many slave boards can be connected to the ASL5115EVBMST?

The ASL5115EVBMST supports up to nine ASL5x15EVBSLAV slave boards in a daisy-chain topology via connectors X1 (master output) and X3 (slave input). Each slave board connects to the master's CAN(FD) bus and receives regulated VCC, allowing synchronized control of up to 108 LED channels (12 × 10 nodes) in a single network.

What software tools are required to configure the ASL5115EVBMST?

Configuration requires the NXP GUI (SW491501), downloadable from NXP DocStore, and the S32K144EVB-Q100 firmware flashed with the appropriate SREC image. Optional tools include Vector CANoe for advanced CAN simulation and the Excel Emulator Tool for offline MTP register generation - all referenced in UM11224 Rev. 1 (28 May 2019).
