Nanjing Qinheng Microelectronics Co., Ltd. focuses on connectivity technology and microprocessor kernel research, and is an integrated circuit design enterprise that builds chips based on self-developed professional interface IP and microprocessor kernel IP. The company is committed to providing customers with chips and solutions for the interconnection of everything and the interoperability of up and down, and its main products include USB/Bluetooth/Ethernet interface chips and connected/interconnected/wireless MCUs, which focus on connection, networking and control. The company's chip design focuses on tracing back to the origin, underlying construction and vertical specialisation. We first research key or common IP components such as cores and interfaces, then build finished chips based on each IP component, supplemented by upper layer protocol stack software and computer terminal drivers, and finally form professional products or solutions. Among them, the combination of microprocessor core and USB and other professional interface technology matrix forms a rich product category. The proprietary IP system enhances the flexibility of chip architecture and saves the cost of outsourcing IP components. The company's in-depth research on the underlying IP components and optimisation of the articulation of each component have improved the overall performance of the products, reduced power consumption and enhanced efficiency, forming a long-term marginal cost advantage and sustainable competitiveness from the surface to the inside and from the core to the nucleus.
