MLX81109KLW-CAE-000-SP

Application Specific Microcontrollers Overview

The MLX81109KLW-CAE-000-SP is a LIN slave controller from Melexis, integrating a 16-bit RISC MCU with 32kB flash, RAM, and EEPROM. It features an integrated LIN transceiver compliant with LIN 2.x and SAE J2602 standards. The device includes four programmable constant current high-voltage I/Os capable of 48mA output, eight low-voltage I/Os, and a 16-bit PWM output. Designed for automotive environments, it operates within a temperature range of -40°C to 125°C and utilizes a QFN-20 (5x5mm) package.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix '000' against the datasheet to confirm exact configuration options, as suffixes often denote variations in packaging or initial programming. Confirm AEC-Q100 qualification status and export compliance requirements prior to ordering. Ensure the QFN-20 thermal pad soldering process aligns with automotive manufacturing standards.

Application Specific Microcontrollers Selection Notes

Select this component when a single-chip solution for LIN communication and LED/IO control is required. Compare pin counts and current capabilities against the MLX81107 if fewer I/Os are sufficient. Consider the MLX81115 if driving six LEDs is necessary instead of four. Verify that the 32kB flash capacity meets application firmware requirements.

Application Specific Microcontrollers Part Context

This part belongs to the MLX81109 family of LIN slave controllers designed for cost-effective automotive networking. It shares core architecture with the MLX81107 but offers enhanced integration in a compact QFN5x5 package. The series targets applications requiring robust LIN communication alongside direct control of external components like LEDs or switches.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the MLX81107 for similar functionality with potentially different I/O configurations. Cross-reference with MLX81115 if higher LED channel count is needed.
