MLX81114KDC-AAB-000-RE

Application Specific Microcontrollers Overview

The MLX81114KDC-AAB-000-RE is a single-chip LIN RGB controller designed for automotive ambient lighting applications. It integrates a 16-bit pipelined RISC microcontroller with 32 kB Flash, 2 kB RAM, and 512 B EEPROM, alongside a math co-processor for 32-bit MUL/DIV operations. The device features four high-voltage I/Os providing configurable current sources up to 60 mA for RGB+W LED configurations. It includes a LIN transceiver compliant with LIN 2.x and SAE J2602 standards, supporting baud rates up to 19.2 kBaud. Key electrical parameters include a sleep mode standby current of typ. 25 µA (max 50 µA), an internal RC oscillator operating up to 32 MHz, and operation within the automotive temperature range of -40 °C to 125 °C.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix KDC-AAB-000-RE against the manufacturer's official documentation to confirm package type, tape-and-reel quantity, and regional compliance certifications. Ensure the selected variant matches the required PCB footprint and mass production packaging specifications before finalizing procurement orders.

Application Specific Microcontrollers Selection Notes

Select the MLX81114 over the MLX81113 when memory access protection is required for security-sensitive automotive applications. Confirm that the 60 mA per channel current capability meets the LED load requirements. Verify compatibility with the vehicle's LIN bus topology, specifically regarding auto-addressing support and baud rate settings up to 19.2 kBaud.

Application Specific Microcontrollers Part Context

The MLX81114 is part of Melexis' LIN RGB controller family, serving as the secure variant of the MLX81113. It shares the same core architecture but adds hardware-level memory protection features. This component is positioned for cost-efficient, high-performance ambient lighting solutions in modern vehicles, integrating physical layer communication, protocol handling, and LED driving on a single chip.

Application Specific Microcontrollers Replacement Considerations

The MLX81113 is the pin-compatible base model without memory protection. For higher channel counts, consider the MLX81115 (dual-channel) or MLX81123 (fourth-generation). Verify functional equivalence and safety integrity levels (ASIL-A for MLX81114 vs ASIL-B for newer models) during substitution planning.
