Arm Technology Empowers Efficient Chip Creation
Seizing Opportunities in the Smart Automotive Market
In the era of smart electric vehicles, automotive MCUs are undergoing a transformation of “quantity and quality improvement”: on one hand, MCU applications are expanding to all scenarios of body, power, chassis, intelligent cockpit, and intelligent driving, significantly increasing demand; on the other hand, the upgrade of automotive electronic and electrical architecture and the penetration of AI technology are driving automotive MCUs from “function realization” to “intelligent collaboration,” which makes the market’s requirements for automotive MCUs in terms of high performance, high real-time capability, and high security increasingly stringent. These performance indicators have also become key standards for measuring the core competitiveness of automotive MCUs.
This trend brings market opportunities for chip companies while also presenting challenges in technology, development, business, and cost. As the most widely used computing platform globally, Arm technology, with its high energy efficiency, mature ecosystem, and flexible scalability, has empowered over 31 billion chips worldwide, making it the mainstream choice for automotive MCUs. Especially for mature companies like Lanshan Electronics with clear R&D and business planning, the Arm Total Access solution can fully meet the innovative needs of enterprises to rapidly develop market-leading products based on Arm’s cutting-edge and diverse technologies.
Leveraging the Mainstream Arm Technology Ecosystem
Building a Full-Scenario Automotive MCU Product Matrix
Lanshan Electronics is an automotive semiconductor company focused on automotive MCUs and supporting power chips and “end-to-end” solutions. The company has built a full-scenario automotive-grade chip matrix through forward R&D, covering ARM cores from M0, M4, M7, R52 series to self-developed RISC-V architecture, with power management chips achieving full-link layout from BMS to domain controller power supply.
By leveraging Arm’s globally leading technology ecosystem, Lanshan Electronics has built a fully self-developed automotive-grade MCU product portfolio and supporting power chips within three years, covering high, mid, and low-end application scenarios, aligning with different automotive electronic and electrical architectures, and fully meeting the full-scenario needs of smart vehicles.
High-end flagship LS-N636 product: equipped with a triple-core Arm Cortex®-R52, using advanced automotive-grade eFlash technology, meeting the highest safety level of ASIL-D, applied in core areas such as power domain control and intelligent chassis, representing the leading level of domestic domain control MCUs.
Performance pioneer LS-E3X series: using Cortex-M7 core, covering single-core to quad-core, with multiple IO ports and packaging forms, applicable to various body control applications.
Mid-range mainstay LS-E14X series: based on Cortex-M4F core, equipped with high-performance independent HSM module, supporting hardware asymmetric encryption to meet stringent information security regulations.
Economical choice LS-E10X series: relying on Cortex-M0+ core, flexibly innovating in functional safety, communication modules, etc., adaptable to various body electronic scenarios.
Currently, Lanshan Electronics’ series products are progressing smoothly. The LS-E14X series has been mass-produced and installed in multiple leading customers, while the LS-N636, LS-E3X, and LS-E10X are about to enter mass production. In the future, Lanshan Electronics will continue to develop multiple series of automotive MCUs based on Arm Cortex-R52 and Cortex-M cores, focusing on high-end product development to meet the new demands of domain control in the next 5-10 years.
