MLX81113KDC-BBB-000-RE

Application Specific Microcontrollers Overview

The MLX81113KDC-BBB-000-RE is a fully integrated low-end LIN slave controller designed for automotive ambient lighting applications. It drives RGB LEDs via the LIN bus, combining a physical layer transceiver, protocol controller, and current-controlled outputs. The device features a 16-bit RISC microcontroller with 32 kByte Flash, 2 kByte RAM, and 576 Byte EEPROM. It includes four high-voltage I/Os capable of sourcing up to 60 mA each, supporting RGB+W configurations. The IC operates within an automotive temperature range of -40 °C to 125 °C and supports LIN 2.x and SAE J2602 standards.

Application Specific Microcontrollers Procurement Notes

Verify package type and reel quantity against official documentation before ordering. The suffix indicates a specific packaging format; confirm compatibility with automated assembly equipment. Ensure compliance with export regulations if applicable. Check for updated datasheets to verify current revision status and any potential design changes.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring a cost-effective LIN-based solution for multi-color LED control. Verify that the 60 mA per channel output current meets the LED requirements. Confirm that the ASIL-A safety classification aligns with the system's functional safety goals. Ensure the SOIC8EP package fits the PCB layout constraints.

Application Specific Microcontrollers Part Context

This part belongs to the MLX81113 family of LIN RGB controllers from Melexis. It serves as a dedicated slave node in LIN networks, simplifying the development of ambient lighting systems by integrating MCU, LIN PHY, and LED drivers into a single chip. It is distinct from higher-channel devices like the MLX81143 which use the MeLiBu protocol.

Application Specific Microcontrollers Replacement Considerations

Direct replacements must match the SOIC8EP package, 4-channel 60mA output capability, and LIN 2.x interface. Verify pinout compatibility and electrical parameters such as supply voltage range (-40°C to 125°C) and standby current consumption.
