Overview
The MLX81120KLW-AAD-100-SP is a fully integrated LIN RGB controller and LIN-to-LIN gateway designed for automotive ambient lighting. It features a 16-bit MULAN MCU with 32 kB Flash, 16 kB ROM, 2 kB RAM, and 512 B NVRAM. The device includes two LIN transceivers compliant with LIN 2.x and SAE J2602 standards, supporting baud rates up to 19.2 kBaud. It provides four high-voltage I/Os with configurable current sources up to 48 mA and four 16-bit PWM outputs for RGB+W LED control. Operating conditions range from 5.5 V to 18 V supply voltage and -40°C to +125°C temperature.
Feature Summary
- Dual LIN Transceivers: Supports LIN-to-LIN gateway functionality and autoconfig via bus shunt method.
- Integrated MCU: 16-bit MULAN core with 32 kB Flash, 16 kB ROM, 2 kB RAM, and math co-processor.
- LED Drivers: Four high-voltage I/Os with programmable current sources (up to 48 mA) and 16-bit PWM outputs.
- Diagnostic & ADC: Includes 10-bit ADC with DMA, LED diagnostic capabilities, and battery/temperature monitoring.
Applications
- Automotive ambient lighting modules
- LIN RGB slave controllers
- LIN-to-LIN gateway extensions
Procurement Notes
Verify the specific ordering suffix 'KLW-AAD-100-SP' against the manufacturer's latest documentation to confirm package type, tape/reel specifications, and regional export restrictions. Ensure compliance with automotive qualification standards required for the target application environment.
Selection Notes
Select this component when a dual-LIN interface is required for network expansion alongside RGB LED driving. The DFN12 4x4 package suits space-constrained designs. Verify that the 48 mA output current per channel meets the LED load requirements and that the 32 kB Flash capacity is sufficient for custom application firmware.
Part Context
This part belongs to the MLX81120 family of LIN RGB controllers. It serves as a low-end LIN slave node capable of acting as a master for sub-networks. The device integrates physical layer transceivers, protocol controllers, and current-controlled outputs to simplify ambient light module development.
Replacement Considerations
Consult Melexis documentation for pin-compatible or functionally equivalent alternatives within the MLX811xx series. Verify memory sizes, package dimensions, and electrical characteristics before substitution.
