NXP Semiconductors ASL5015EVBSLAV

Overview

ASL5015EVBSLAV from NXP Semiconductors is a slave evaluation board for the ASL5x15 Matrix LED Controller (MLC) family, pre-populated with the ASL5015SHN IC. It supports 12-channel LED segment control at up to 1.5 A per channel, communicates via UART (TXD/RXD) with master boards, and enables CAN(FD)-based system-level diagnostics and dimming profile configuration in automotive adaptive lighting applications.

For engineers reviewing the ASL5015EVBSLAV datasheet, ASL5015EVBSLAV pinout, ASL5015EVBSLAV application, or ASL5015EVBSLAV equivalent, this page delivers verified hardware interface details, confirmed slave-board functionality, UART/CAN(FD) integration requirements, and real-world evaluation workflow constraints - all specific to the ASL5015EVBSLAV variant.

Technical Context

The ASL5015EVBSLAV implements a dedicated slave node in a hierarchical MLC architecture, receiving commands and power from a master board (e.g., ASL5015EVBMST) via X1/X3 connectors. It lacks on-board CAN transceiver or SBC, relying entirely on UART-based command forwarding and +12 V supply distribution from the master.

It integrates the ASL5015SHN HVQFN-packaged MLC IC, which provides SMART PWM channel control, integrated diagnostics (open/short detection, thermal monitoring), and Multi-Time Programmable (MTP) memory for configuration persistence - all accessible through host MCU or GUI-driven CAN(FD) messaging routed via the master.

FAQ

What is the primary function of the ASL5015EVBSLAV evaluation board?

The ASL5015EVBSLAV is a slave evaluation board designed to extend the channel count of an ASL5x15-based matrix LED system. It hosts the ASL5015SHN IC and connects to a master board (e.g., ASL5015EVBMST) via UART and +12 V supply, enabling distributed control of up to 12 additional LED segments without adding CAN transceivers or microcontrollers. The ASL5015EVBSLAV itself does not process CAN messages - it relays commands from the master and executes local PWM output control.

Can the ASL5015EVBSLAV operate independently without a master board?

No. The ASL5015EVBSLAV has no onboard CAN transceiver, SBC, or standalone power regulation. It relies entirely on the master board for +12 V supply, CAN(FD) protocol handling (via UJA1163), and command translation into UART instructions for the ASL5015SHN IC. Attempting standalone operation will result in no functional output or communication - the ASL5015EVBSLAV is strictly a dependent slave node.

Which connectors are essential for integrating the ASL5015EVBSLAV into a working system?

Two connectors are mandatory: X1 (for UART communication and +12 V supply from master) and X2 (for connecting customer LED boards to SW0–SW15 outputs). Connector X3 is optional and used only when daisy-chaining additional slave boards downstream. Pin assignments are fixed per UM11224: X1 pins 1–4 = GND/TXD/RXD/VCC; X2 pins 1–16 = SW15 to SW0; NTC and ID pins are reserved for thermal/resistor identification on LED boards.

Does the ASL5015EVBSLAV support CAN FD directly, or only through the master board?

The ASL5015EVBSLAV does not support CAN FD directly. It contains no CAN physical layer circuitry. All CAN FD communication is handled exclusively by the master board's UJA1163 System Basic Chip (SBC). The ASL5015EVBSLAV receives translated UART commands from that master and executes local actions - meaning CAN FD capability is inherited, not native, and depends entirely on correct master-board configuration and firmware.

How is device addressing configured on the ASL5015EVBSLAV?

Device addressing is set using a 5-position DIP switch (S1-1 to S1-5) linked to ASL5015SHN address pins A4–A0. Each switch position corresponds to one bit: ON = logic 0 (grounded), OFF = logic 1 (pulled high). This yields a 5-bit CAN address (0x00–0x1F) used by the master to route commands. Address conflicts must be avoided across all slaves on the same bus - the ASL5015EVBSLAV's address is only relevant during CAN message routing and has no effect on UART-level operation.
