In today's rapidly advancing technology, precise positioning and posture perception technology have become an indispensable part of many fields. IMU (Inertial Measurement Unit) products, with their high precision and stability, are not only used in high-tech fields such as aerospace, robotics and motion analysis, autonomous driving and unmanned systems, but also deeply integrated into our daily lives such as smartphones, VR/AR experiences, etc. The high-performance inertial measurement unit LINS620, embedded with the motion control MCU HPM5300 series chip from Shanghai Xianji Semiconductor Technology Co., Ltd. (hereinafter referred to as "Xianji Semiconductor"), launched by Wuxi LINS  Technology Co., Ltd. (hereinafter referred to as "LINS  Technology"), has the characteristics of small size, light weight, strong earthquake resistance and overload resistance. LINS620 is equipped with a three-axis gyroscope and three-axis accelerometer. The gyroscope has a zero bias of 0.8 °/h (Allan) and the accelerometer has a zero bias of 20ug (Allan) during stable operation. It is used for precise navigation, control, and dynamic measurement of the carrier, and adopts high-precision MEMS inertial devices with high reliability and hardness. It can accurately measure the angular velocity and acceleration of the moving carrier even in harsh environments.

As a sensor system integrator that integrates data, software, and services, LINS Technology insists on making the best IMU products in China. Xianji chips provide excellent support for our IMU products with their high performance, low power consumption, rich interfaces, and powerful analog performance, making our IMU products more competitive in the fields of navigation, positioning, and control, and providing customers with a better user experience.

——Founder of LINS Technology, Zhao Wei

Not only does LINS Technology have excellent research and development technology, but it also has the production capacity for large-scale production, which can produce 20000 sets of products per month. With a new factory of 1500 square meters in Wuxi and a newly built production base in Jiujiang, Jiangxi, the annual output can reach 500000 sets. At present, more than ten products have been mass-produced, including the latest LINS620 high-performance inertial measurement unit embedded with HPM5300 chip.

The R&D team of LINS Technology stated that when selecting the HPM5300 series chip from Xianji Semiconductor for this IMU product, the main consideration was that this chip has the following advantages, which can meet the actual needs of IMU products and enhance the overall performance and competitiveness of the product.

HPM5300 has high computing power and stability, which can support the accuracy and reliability of IMU product measurement.

Efficient data processing capabilities and low power consumption to extend the device's usage time.

High integration and smaller packaging are more conducive to integration into IMU devices.

Has good compatibility and scalability to meet the needs of future IMU product upgrades and feature expansion.

Finally, the HPM5300 series has a high cost performance ratio, and advanced enterprises can provide AEC-Q100 certification and other related qualification guarantees to ensure the safety and stability of products and supply chains.

The HPM5300 series is a high-performance motion control MCU released by Xianji Semiconductor in mid-2023. It supports double precision floating-point operations and powerful DSP expansion, with a main frequency of 480MHz, reaching or even surpassing international mainstream high-performance MCU products, meeting the development needs of most application scenarios. The insufficient frequency of the main control chip is no longer a bottleneck that limits the operation and control capabilities. The HPM5300 series can achieve high-speed computing while increasing bandwidth, which brings faster command response time. Combined with HPM5300's unique independent knowledge product "high-precision position sensor system", it supports mainstream multiple types of position sensors, bringing a unique experience to motion control.

With the continuous development of cutting-edge technologies such as artificial intelligence, the Internet of Things, and 5G in recent years, the demand for sensors in the market is gradually increasing. Among inertial sensor products, IMU has the largest market share. According to research by Xinmou, the domestic IMU market is expected to reach 4.31 billion yuan in 2022 and 7.55 billion yuan in 2027, with an average annual compound growth rate of 11.9%. The market is booming and presenting unlimited business opportunities. Xianji Semiconductor will continue to work with LINS Technology to launch more high-performance IMU series, hoping to enable global customers to use MEMS inertial navigation products designed and manufactured in China with embedded Xianji chips.
