MLX81107KLQ-CAA-000-TU

Application Specific Microcontrollers Overview

The MLX81107KLQ-CAA-000-TU is a LIN slave controller from Melexis, designed for automotive applications. It integrates a 16-bit RISC microcontroller with 24 kB of flash memory and provides 12 I/O pins. The device operates within a supply voltage range of 5.5 V to 18 V and supports temperatures from -40°C to +125°C. Housed in a QFN-20 package, it features an SPI interface for configuration and communication. This component is categorized as NRND (Not Recommended for New Designs), indicating that while functional, it is not the preferred choice for new development projects.

Application Specific Microcontrollers Procurement Notes

This part number is designated as NRND (Not Recommended for New Designs). Engineers should verify if newer alternatives are available for new projects. Existing designs may continue production, but long-term availability is not guaranteed. Verify package type and suffix codes carefully during procurement to ensure compatibility with existing PCB footprints and firmware configurations.

Application Specific Microcontrollers Selection Notes

Select this component only for maintenance or legacy design updates where the MLX81107 family is already established. For new designs, evaluate current Melexis LIN controllers with higher integration or updated feature sets. Ensure the 12 I/O count and 24 kB flash capacity meet specific application requirements before finalizing selection.

Application Specific Microcontrollers Part Context

The MLX81107 series represents Melexis' earlier generation of smart LIN slaves, combining MCU capabilities with direct I/O driving. It serves as a bridge between the LIN network and local actuators or sensors. The KLQ variant specifically denotes the QFN-20 package option, distinguishing it from other pinout or thermal variants within the same product family.

Application Specific Microcontrollers Replacement Considerations

As an NRND part, check for official Melexis replacement recommendations. Potential successors may include updated MLX811xx series devices with increased memory or enhanced diagnostic features. Verify pin-to-pin compatibility if substituting directly into existing hardware layouts.
