MLX81113KLW-BBB-000-SP

Application Specific Microcontrollers Overview

The MLX81113KLW-BBB-000-SP 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 LIN transceiver, protocol controller, and current-controlled outputs. The device features a 16-bit pipelined 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 Feature Summary

• Integrated 16-bit RISC MCU with 32 kB Flash, 2 kB RAM, and math co-processor
• Four configurable constant current sources (up to 60 mA) for RGB+W LED control
• LIN 2.x/SAE J2602 compliant transceiver with auto-addressing support
• DFN-WF-10 (3x3 mm) package with exposed pad

Application Specific Microcontrollers Applications

• Automotive interior ambient lighting modules
• Color-changing cabin illumination systems
• Door trim and overhead console lighting

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and packaging type. Ensure that the DFN-WF-10 footprint matches the target PCB design requirements. Confirm export authorization status if applicable, as certain regions may require prior approval for this component.

Application Specific Microcontrollers Selection Notes

Select this component when a compact solution for multi-color ambient lighting is required. The MLX81113KLW variant offers a smaller form factor compared to the SOIC8 version. Ensure the application utilizes the LIN bus architecture and requires independent current control for Red, Green, Blue, and potentially White channels.

Application Specific Microcontrollers Part Context

This part belongs to the Melexis MLX81113 family of single-chip LIN RGB controllers. It serves as a cost-effective alternative to discrete driver solutions by integrating the MCU, LIN interface, and power stages into one package. It is distinct from the MLX81114, which adds memory access protection features.

Application Specific Microcontrollers Replacement Considerations

The MLX81113KDC-BBB-000-SP is a functional equivalent in a different SOIC8EP package. Verify mechanical fit and thermal performance differences between the DFN-WF-10 and SOIC8 packages before substitution.
