LX Semicon Mass Produces Automotive MCU LX61101 for Hyundai Motor, Kia



- This marks the first achievement of LX Semicon’s new automotive MCU business as it expands into automotive semiconductors.

- It is also the first domestically produced MCU for Hyundai Motor, Kia, based on a domestic mass production system spanning the entire SCM process.

LX Semicon has begun mass production of LX61101, an automotive motor control microcontroller unit (MCU) for Hyundai Motor and Kia.
This marks LX Semicon’s first achievement in automotive MCUs, a new business it has been developing, and the first domestically produced MCU to be used in Hyundai Motor and Kia vehicles.


LX61101 is an MCU optimized for motor control in automotive body electronics. It is a core system semiconductor that enables real-time motor control by monitoring speed, position, rotational direction, and torque,
and is characterized by an ultra-compact design, high performance, and high system efficiency. In particular, LX61101, based on a 40 MHz ARM Cortex-M3 core, enables stable and precise motor control.
The chip is used in automotive window safety systems, which automatically reverse direction and reopen the window when an o-bject is detected during closing, as well as in systems that control automotive aerodynamics.
Beginning with vehicles that Hyundai Motor and Kia plan to produce in the second half of this year, LX61101 will be applied to a broader range of vehicle models.


LX61101 marks LX Semicon’s first achievement in the automotive MCU sector as part of its new business initiative.
The company has expanded its business with a focus on display driver integrated circuits (DDIs). Since 2022,
LX Semicon has nurtured automotive MCUs as one of its future growth pillars, driven by business portfolio expansion, the restructuring of the global automotive supply chain, and the shift toward electrification.
It aims to expand its business areas by leveraging its competitive MCU technology for home appliances.


LX61101 is attracting industry attention as the first domestically produced MCU to be used in Hyundai Motor and Kia vehicles.
LX Semicon was selected as a new business partner for a motor-specialized MCU through Hyundai Motor and Kia’s supplier selection process in March 2023 and received a supplier award in April of the same year.
After three years of development and quality testing, LX Semicon succeeded in mass-producing LX61101. During the development process, LX61101 satisfied AEC-Q100, the automotive semiconductor reliability standard,
and ISO 26262, the functional safety standard.


LX61101 was developed and mass-produced with the support of domestic companies across the full supply chain management (SCM) process, including semiconductor design, foundry manufacturing, and back-end processing.
Industry observers view this as significant because it lays the foundation for domestic automotive MCU production and represents the first case in which Korea's leading fabless semiconductor company, LX Semicon, Hyundai Motor and Kia,
and the domestic system semiconductor manufacturing and back-end processing ecosystem have been integrated into a single domestic supply chain.


As of 2025, the size of the global automotive MCU market was estimated at approximately KRW 15.5 trillion. An LX Semicon official said,
“As part of our long-term strategy to cultivate the automotive MCU sector, we will broaden our product portfolio from control MCUs to communication, drive, sensor, and power MCUs.
LX Semicon will pursue new growth opportunities in automotive semiconductors and strengthen our collaboration with domestic automakers and the semiconductor industry.”
