MLX81114KDC-AAB-000-SP

Application Specific Microcontrollers Overview

The MLX81114KDC-AAB-000-SP is a single-chip LIN RGB controller designed for automotive ambient lighting applications. It integrates a 16-bit RISC microcontroller, LIN transceiver, and four high-voltage current-controlled outputs capable of driving up to 60 mA per channel for RGB+W configurations. Key specifications include 32 kB Flash, 2 kB RAM, and 512 B EEPROM. The device supports LIN 2.x and SAE J2602 standards with baud rates up to 19.2 kBaud. It features memory protection options, diagnostic capabilities for LED faults, and operates within an automotive temperature range of -40°C to 125°C.

Application Specific Microcontrollers Feature Summary

• Integrated 16-bit pipelined RISC MCU with math co-processor for 32-bit MUL/DIV operations
• Four high-voltage I/Os with configurable current sources (up to 60 mA) and 16-bit PWM outputs
• Memory protection option for anti-theft security applications
• LIN transceiver supporting autoaddressing via bus shunt method

Application Specific Microcontrollers Applications

• Automotive interior ambient lighting modules
• RGB+W LED color control systems
• Anti-theft vehicle lighting applications requiring memory protection

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix KDC-AAB-000-SP against official Melexis documentation to confirm package type, tape-and-reel quantity, and regional availability. Ensure compliance with ISO26262 ASIL-A safety requirements if integrating into safety-critical systems. Confirm that the memory protection feature aligns with the intended application security needs.

Application Specific Microcontrollers Selection Notes

Select the MLX81114 over the MLX81113 when memory access protection is required for security purposes. Choose this component for applications needing up to four independently controlled current sources with diagnostic feedback. Consider the SOIC8 or DFN10 package based on thermal management and PCB space constraints.

Application Specific Microcontrollers Part Context

The MLX81114 is part of the MLX811xx family of LIN RGB controllers from Melexis. It extends the functionality of the MLX81113 by adding a memory protection option. This family targets cost-efficient development of ambient light modules connected to LIN bus systems in vehicles.

Application Specific Microcontrollers Replacement Considerations

The MLX81113 is a functional equivalent without the memory protection feature. Verify pin compatibility and software configuration differences before substitution.
