MLX81109KLW-CAE-000-RE

Application Specific Microcontrollers Overview

The MLX81109KLW-CAE-000-RE is a LIN slave controller from Melexis, designed for IO expansion and interior lighting applications. It integrates a 16-bit RISC MCU with 32kB flash, RAM, and EEPROM, alongside a LIN transceiver compliant with LIN 2.x and SAE J2602 standards. The device features four programmable constant current/high-voltage I/Os, eight low-voltage I/Os, and a 16-bit PWM output. It operates within an automotive temperature range of -40°C to 125°C and utilizes a QFN-20 (5x5) package.
