LX Semicon has begun supplying its first automotive microcontroller unit (MCU) to Hyundai Motor and Kia, marking the first tangible achievement of its automotive semiconductor business. The company said Monday that it has begun mass production of the LX61101, an MCU optimized for motor control in automotive body electronics. The chips will initially be used in vehicles that Hyundai Motor and Kia begin producing in the second half of this year, with applications set to gradually expand to a wider range of models. Based on a 40-megahertz Arm Cortex-M3 core, the chip enables stable and precise motor control by monitoring speed, position, rotational direction and torque in real time. The chip will be used in vehicle window safety systems, which automatically reverse direction and reopen a window when an object is detected while it is closing, as well as in systems that control vehicle aerodynamics. LX Semicon said the chip marks the company’s first tangible achievement in its automotive MCU business, a new growth area it has been fostering since 2022 to diversify its portfolio beyond displ
