Nanjing Qinheng Microelectronics Co., Ltd. focuses on the research of connection technology and microprocessor cores. It is an integrated circuit design company that builds chips based on self-developed professional interface IP and microprocessor core IP. The company is committed to providing customers with chips and solutions that connect everything and communicate with each other. Its main products include USB/Bluetooth/Ethernet interface chips and connection/interconnection/wireless MCUs. The products focus on connection, networking and control. The company's chip design focuses on tracing the origin, bottom-level construction and vertical specialization. First, key or common IP components such as cores and interfaces are studied, and then finished chips are built based on each IP component, supplemented by upper-layer protocol stack software and computer-side drivers, and finally professional products or solutions are formed. Among them, the combination of microprocessor cores and professional interface technology matrices such as USB has formed a rich product category. The independent IP system enhances the flexibility of the chip architecture and saves the cost of purchasing IP components. The company conducts in-depth research on underlying IP components and optimizes the connection between components, which improves the overall performance of the product, reduces power consumption, and improves efficiency, forming a long-term marginal cost advantage and sustainable competitiveness from the outside to the inside and from the core to the core. Main product brand: WCH, full name WinChipHead Product positioning: professional, easy to use Application areas: computer and mobile phone peripherals, industrial control, Internet of Things, etc.
