MLX81107KLW-CAA-000-TU

Application Specific Microcontrollers Overview

The MLX81107KLW-CAA-000-TU is a Melexis automotive-grade LIN controller IC designed for smart lighting and actuator applications. It integrates a 16-bit RISC microcontroller with 32 kB of flash memory, a physical layer LIN transceiver compliant with LIN 2.0/2.1/2.2 standards, and an on-chip voltage regulator. The device features eight low-voltage I/O pins and four high-voltage (12V DC) I/O pins, enabling direct control of external components. It operates within a junction temperature range of -40°C to 125°C and includes protection mechanisms such as over-temperature shutdown and load dump tolerance up to 40V.

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'TU' against official Melexis documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the component meets AEC-Q100 Grade 1 requirements for your target automotive environment. Cross-reference the full part number with current datasheets to confirm pinout compatibility and firmware availability for the CAA variant.

Application Specific Microcontrollers Selection Notes

Select this IC when a single-chip solution is required to combine LIN communication with direct high-side or low-side switching capabilities. It is suitable for designs aiming to reduce bill-of-materials costs by integrating the MCU, LIN PHY, and power regulation into one package. Consider the 32 kB flash size for application complexity and verify that the integrated IO drivers meet the current requirements of the connected loads without external buffering.

Application Specific Microcontrollers Part Context

The MLX81107 belongs to Melexis' family of cost-optimized LIN controllers, positioned alongside the MLX81109. These devices are engineered to simplify the implementation of complex LIN bus nodes by merging processing, communication, and drive functions. This integration allows for smaller module footprints and reduced design effort compared to discrete MCU and LIN transceiver combinations.

Application Specific Microcontrollers Replacement Considerations

The MLX81109KLW-CAE-100-RE is a related device within the same product family, offering similar LIN and MCU functionalities but potentially differing in package type (QFN-20 vs SOIC-8) or specific IO configurations. Verify electrical pinouts and software compatibility before substituting.
