About SiMicro

Since its establishment, Guangdong Saiwei Microelectronics Co., Ltd. (stock code: 688325) has been committed to the research and development and sales of analog chips. It has advanced analog and mixed-analog integrated circuit design, development, manufacturing and testing experience and technology. The company's products revolve around battery management chips and extend to the field of power management chips. It insists on forward design and takes independent research and development and technological innovation as the foundation of the company. At present, the company's products include battery safety chips, battery metering chips, charging management and other chips. The products are widely used in terminal products of well-known brands in the industry such as laptops and tablets, smart wearable devices, power tools, charging products, light electric vehicles, smart home appliances, smart phones, drones, etc. In 2016, through the wholly-owned acquisition of Ruitong Xinyuan, it acquired the controlling stake of Silex, a Swedish company leading the world's leading MEMS pure foundry. Saiwei's main business today is the MEMS business. In the first half of 2023, Saiwei's MEMS wafer manufacturing business revenue was 232 million yuan, accounting for 58% of total revenue; MEMS process development revenue was 129 million yuan, accounting for 33% of total revenue. Saiwei's business is very simple, mainly two parts, MEMS business and GaN material business. Saiwei's MEMS products are closely linked to the largest MEMS market segments (RF filters, pressure sensors, combined inertial sensors, silicon microphones), and have a high ceiling for future growth. In addition, Saiwei's subsidiary, Sweden's Silex, has the most complete MEMS product line in the industry, and Saiwei has also put a high-tech hard-core product, MEMS-IMU, into mass production.
